cause actual results to differ materially from those contained in any forward-looking statement. We do not

(1) As holders of Class A and Class B ordinary shares have the same dividend right and the same participation right
in our undistributed earnings, the basic and diluted net income per share of Class A and Class B ordinary shares
are the same for all the periods presented during which there were two classes of ordinary shares. Prior to the
creation of the two classes of ordinary shares in May 2005, we only had one class of ordinary shares. For the
periods during which there were two classes of ordinary shares, the weighted average number of ordinary shares
represents the sum of the weighted average number of Class A and Class B ordinary shares. Please see
“Earnings per Share” under Note 2 to our audited consolidated financial statements included in this annual
report for additional information regarding the computation of the per share amount and the weighted average
numbers of Class A and Class B ordinary shares.

(2) As holders of Class A and Class B ordinary shares have the same dividend right and the same participation right
in our undistributed earnings, the basic and diluted pro forma earnings per share of Class A and Class B ordinary
shares are the same for all the periods presented.

Exchange Rate Information

Our business is primarily conducted in China and substantially all of our revenues are denominated in RMB.
However, periodic reports made to shareholders will include current period amounts translated into U.S. dollars
using the then current exchange rates, for the convenience of the readers. The conversion of RMB into U.S. dollars
in this annual report is based on the noon buying rate in The City of New York for cable transfers of RMB as certified
for customs purposes by the Federal Reserve Bank of New York. Unless otherwise noted, all translations from RMB
to U.S. dollars and from U.S. dollars to RMB in this annual report were made at a rate of RMB6.8225 to US$1.00,
the noon buying rate in effect as of December 31, 2008. We make no representation that any RMB or U.S. dollar
amounts could have been, or could be, converted into U.S. dollars or RMB, as the case may be, at any particular rate,
or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of
the conversion of RMB into foreign exchange and through restrictions on foreign trade. On April 3, 2009, the noon
buying rate was RMB6.8343 to US$1.00.

The following table sets forth information concerning exchange rates between the RMB and the U.S. dollar for

the periods indicated.

Risks Related to Our Business

If online marketing is not more widely adopted in China, our ability to increase revenue and profitability
could be materially and adversely affected.

The use of the Internet as a marketing channel is at an early stage in China. Internet and broadband penetration
rates in China are both relatively low as compared to those in most developed countries. Many of our current and
potential customers have limited experience with the Internet as a marketing channel, and historically have not
devoted a significant portion of their marketing budgets to online marketing and promotion. As a result, they may
not consider the Internet an effective channel to promote their products and services as compared to traditional print
and broadcast media. Our ability to increase revenue and profitability may be negatively impacted by a number of
factors, many of which are beyond our control, including:

(cid:129) difficulties associated with developing a larger user base with demographic characteristics attractive to

customers;

(cid:129) increased competition and potential downward pressure on online marketing prices;

(cid:129) higher customer acquisition costs due in part to the limited experience of small to medium-sized enterprises,

or SMEs, with the Internet as a marketing channel;

(cid:129) failure to develop an independent and reliable means of verifying online traffic;

(cid:129) ineffectiveness of our online marketing delivery, tracking and reporting systems; and

(cid:129) lack of increase in Internet usage in China.

Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our
business and operating results may be harmed.

We believe that our brand “Baidu” has contributed significantly to the success of our business. We also believe
that maintaining and enhancing the “Baidu” brand is critical to increasing the numbers of our users, customers and
Baidu Union members. As our market becomes increasingly competitive, maintaining and enhancing our brand will
depend largely on our ability to remain as an Internet search leader in China, which may be increasingly difficult
and expensive.

Historically, we developed our user base primarily by word-of-mouth and incurred limited brand promotion
expenses. Our initial public offering in 2005 has significantly enhanced our brand recognition. We have also
conducted marketing and brand promotion activities in recent years, but we cannot assure you that these activities
will achieve the brand promotion effect expected by us. If we fail to maintain and further promote the “Baidu”
brand, or if we incur excessive expenses in this effort, our business and results of operations may be materially and
adversely affected. In addition, any negative publicity about our products and services, regardless of its veracity,
could harm our brand image and in turn adversely affect our business and operating results.

We face significant competition and may suffer from a loss of users and customers as a result.

We face significant competition in almost every aspect of our business, particularly from other companies that
seek to provide Internet search services to users and provide online marketing services to customers. In the Chinese
Internet search market, our main competitors include U.S.-based Internet search providers providing Chinese
language Internet search services such as Google and Yahoo! and Chinese Internet companies. These Chinese
competitors include Netease, Sina, Sohu, Tencent and Alibaba. We compete with these entities for both users and
customers on the basis of user traffic, quality (relevance) and quantity (index size) of the search results, availability
and ease of use of products and services, the number of customers, distribution channels and the number of

8

BOM  H03242  009.00.00.00  11

associated third-party websites. In addition, we may face greater competition from our U.S.-based competitors as a
result of, among other things, a relaxation on the foreign ownership restrictions of PRC Internet content and
advertising companies, improvements in online payment systems and Internet infrastructure in China and our
U.S.-based competitors’ increased business activities in China.

Many of our competitors have significantly greater financial resources than we do. They also have longer
operating histories and more experience in attracting and retaining users and managing customers than we do. They
may use their experience and resources to compete with us in a variety of ways, including by competing more
heavily for users, customers, distributors, strategic partners and networks of third-party websites, investing more
heavily in research and development and making acquisitions. If any of our competitors provides comparable or
better Chinese language search experience, our user traffic could decline significantly. Any such decline in traffic
could weaken our brand, result in loss of customers and users and have a material adverse effect on our results of
operations.

We also face competition from other types of advertising media, such as newspapers, magazines, yellow pages,
billboards and other forms of outdoor media, television and radio. Most large companies in China allocate, and will
likely continue to allocate, most of their marketing budgets to traditional advertising media and only a small portion
of their budgets to online marketing and other forms of advertising media. If these companies do not devote a larger
portion of their marketing budgets to online marketing services provided by us, or if our existing customers reduce
the amount they spend on online marketing, our results of operations and future growth prospects could be adversely
affected.

We launched trial (or beta) versions of Baidu Youa, our consumer-to-consumer, or C2C, service and Baidu Hi,
our instant messaging, or IM, service in 2008. We face competition from C2C platforms such as Taobao, Paipai and
Eachnet, and from IM service providers such as QQ and MSN Messenger. If we continue to invest in C2C, IM and
other new services, but cannot compete effectively against the existing leading providers in those areas, we may not
be able to develop a sufficiently large customer and user base for our new services and eventually achieve
profitability from those services, and as a result, our future results of operations and growth prospect could be
materially and adversely affected. Additionally, our Japanese search service faces substantial competition. See
“— Risks Related to Our Business — Our recent expansion into the Japanese market may not be successful.”

If we fail to continue to innovate and provide products and services to attract and retain users, we may
not be able to generate sufficient user traffic levels to remain competitive.

Our success depends on providing products and services that enable users to have a high-quality Internet
experience. We must continue to invest significant resources in research and development to enhance our Internet
search technology and our existing products and services and introduce additional high-quality products and
services to attract and retain users and compete against our competitors. If we are unable to anticipate user
preferences or industry changes, or if we are unable to modify our products and services on a timely basis, we may
lose users and customers. Our operating results may also suffer if our innovations do not respond to the needs of our
users and customers, are not appropriately timed with market opportunities or are not effectively brought to market.
As search technology continues to develop, our competitors may be able to offer search results that are, or that are
perceived to be, substantially similar to or better than those generated by our search services. This may force us to
expend significant resources in order to remain competitive.

If we fail to retain existing customers or attract new customers for our online marketing services, our
business and growth prospects could be seriously harmed.

In 2007 and 2008, we generated approximately 99.8% and 99.9% of our total revenues from online marketing
services, respectively, a substantial majority of which was generated from our P4P services. Our online marketing
customers will not continue to do business with us if their investment does not generate sales leads and ultimately
consumers, or if we do not deliver their web pages in an appropriate and effective manner. Our P4P customers may
discontinue their business with us at any time and for any reason as they are not subject to fixed-term contracts. In
addition, we have in the past removed, and may in the future again remove, questionable paid search listings of some
customers to safeguard the quality of our search results. Such removal, whether temporary or permanent, may cause

the affected customers to discontinue their business with us. Failure to retain our existing customers or attract new
customers for our online marketing services could seriously harm our business and growth prospects. In addition,
third parties may develop and use certain technologies to block the display of our customers’ advertisements and
other marketing products on our baidu.com website, which may in turn cause us to lost our customers and adversely
affect our operating results.

We may not be able to manage our expanding operations effectively.

We commenced operations in 2000 and have significantly expanded our operations since then. We expect this
expansion trend to continue as we grow our user and customer base and explore new market opportunities. To
manage the expansion of our business and potential growth of our operations and personnel, we will be required to
improve operational and financial systems, procedures and controls, and expand, train and manage our growing
employee base. In addition, our management will be required to maintain and expand our relationships with other
websites, Internet companies and other third parties. We cannot assure you that our current and planned personnel,
systems, procedures and controls will be adequate to support our expanding operations.

In addition to expanding our core Chinese language search and online marketing operations, we launched the
trial (or beta) versions of Baidu Youa, our C2C service, and Baidu Hi, our IM service, in 2008 and intend to continue
to develop and provide new products and services to our users and customers in the future. Expansion into new
businesses may present operating and marketing challenges that are different from those that we currently
encounter. If we cannot successfully address these new challenges, we may not be able to recover costs we have
incurred or will incur from developing and marketing new products and services, and our results of operations and
growth prospect may be materially and adversely affected.

We may face intellectual property infringement claims and other related claims that could be time-consuming
and costly to defend and may result in our inability to continue providing certain of our existing services.

Internet, technology and media companies are frequently involved in litigation based on allegations of
infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violations
of other parties’ rights. The validity, enforceability and scope of protection of intellectual property in Internet-
related industries, particularly in China, are uncertain and still evolving. As we face increasing competition and as
litigation becomes more common in China in resolving commercial disputes, we face a higher risk of being the
subject of intellectual property infringement claims.

Our products and services link to materials in which third parties may claim ownership of trademarks,
copyrights or other rights. From time to time, we may be subject to trademark or copyright infringement or related
claims, in China and internationally. For example, we provide search engine facilities capable of finding and
accessing links to downloadable audio, videos, images and other multimedia files and other items hosted on third-
party websites, including search facilities enabling our users to search for files in various ways such as by artist, title,
or via lists of most-searched-for titles and artists. Some of these contents found using our search engine facilities
may be protected by copyright.

In China, uncertainties still exist with respect to the legal standards as well as the judicial interpretation of such
standards for determining liabilities of Internet search providers for providing links to content on third-party
websites that infringe upon others’ copyrights. In December 2007, the People’s High Court of Beijing upheld a
lower court’s ruling in our favor in a case originally filed against us by seven music record companies in 2005
alleging that our MP3 search services had infringed upon their copyrights. The court ruled that our service, which
only provides links to online music hosted on third parties’ websites, does not constitute infringement. In the same
month, however, the People’s High Court of Beijing upheld the decision by another lower court in favor of the
record companies in a suit originally filed by 11 record companies against Yahoo! China, one of our competitors, in
July 2006. In the Yahoo! China case, the court held that Yahoo! China was negligent in failing to remove all links to
the infringing content after receiving notice from copyright holders, including those links that it “should have
known” to have infringing content. In December 2008, the People’s High Court of Beijing, as the trial court,
reiterated in another case filed against us that our MP3 search services do not constitute infringement. The plaintiff
has filed an appeal, which remains pending, with the People’s Supreme Court of China.

Although prior court rulings in China have only limited precedential value, the ruling of the People’s High
Court of Beijing in the Yahoo! China case seems to suggest that the courts in future cases may place the burden on
Internet search providers to remove not only links that have been specifically mentioned in notices of infringement
from right holders, but also links they “should have known” to contain infringing content. Such an interpretation of
the applicable law could subject Internet search providers like us to significant administrative burdens and litigation
risks.

In the United States, the legal standards for determining indirect liability for copyright infringement have been
strengthened by the United States Supreme Court in the decision Metro-Goldwyn-Mayer Studios Inc. v. Grokster,
Ltd., et al., 125 S. Ct. 2764 (2005), or Grokster. The implications of the Grokster decision for search engine services,
such as our MP3 search service, are uncertain and may increase the risk of legal liability. Although we conduct our
business operations outside the United States, we may be subject to U.S. copyright laws, including the legal
standards established by Grokster, by virtue of our listing on the Nasdaq, the ownership of our ADSs or ordinary
shares by U.S. investors, the extraterritorial application of U.S. law by U.S. courts or otherwise. Moreover, we
cannot assure you that Grokster will not influence the legal standards for determining indirect copyright
infringement in other jurisdictions, including China.

In light of the above cases and the associated publicity, copyright owners may monitor their copyrighted
materials more closely worldwide and in China and may seek to enforce their rights under theories of indirect
liability, constructive knowledge of infringing content or otherwise. As a result, we may face increased risks of
being subject to copyright infringement claims relating to our MP3 search service. Furthermore, this same
consideration may also lead to decreased availability of third-party MP3 websites. A portion of our traffic is
generated by users of our MP3 search service. According to Alexa.com, approximately 3.3% of our traffic went to
mp3.baidu.com, our MP3 search platform, as of March 31, 2009. Should we face (as a result of the foregoing
considerations or otherwise) a need or decision to substantially modify, limit, or terminate our MP3 search service,
the user experience could be materially affected, and this in turn may have material adverse impact on our business.

Like many other Internet websites, we provide links to and host certain song lyrics on our websites which may
be protected by copyright. As a result, we may be subject to copyright infringement claims. Moreover, we may be
subject to administrative actions brought by the PRC State Copyright Bureau for alleged copyright infringement,
and as a result may be subject to fines and other penalties and be required to discontinue infringing activities. In
addition, we provide links to images of celebrities and other persons, and may face claims for misappropriation of
publicity rights. To address these and other risks relating to intellectual property infringement, we may be required
to change our business model and service offerings to minimize this risk, which could adversely affect our business
prospects.

Intellectual property litigation is expensive and time-consuming and could divert resources and management
attention from the operations of our business. We are currently named as a defendant in a number of copyright
infringement suits in China in connection with our MP3 and other search services, including a suit filed by three
record companies and a suit filed by the Music Copyright Society of China. See “Item 8A. Financial Information —
Consolidated Statements and Other Financial Information — Legal Proceedings.” If there is a successful claim of
infringement, we may be required to pay substantial fines and damages or enter into royalty or license agreements
that may not be available on commercially acceptable terms, if at all. Our failure to obtain a license of the rights on a
timely basis could harm our business. Any intellectual property litigation and/or any negative publicity by third
parties alleging our intellectual property infringement could have a material adverse effect on our business,
reputation, financial condition or results of operations.

We have been and may continue to be subject to claims based on the content found on our websites or
the results in our paid search listings.

In addition to the content developed by ourselves and posted on our websites, our users are free to post
information on Baidu Post Bar, Baidu Knows, Baidu Encyclopedia and other sections of our websites, and our P4P
customers may create text-based descriptions and other phrases to be used as text or keywords in our search listings.
We have been and may continue to be subject to claims for defamation, negligence or other legal theories based on
the content found on our websites. Claims for defamation, negligence or other legal theories based on the content

found on our websites, with or without merit, may result in diversion of the attention of our management personnel
and our financial resources and negative publicity on our brand and reputation. Furthermore, if the content posted on
our websites contains information that government authorities find objectionable, our websites may be shut down
and we may be subject to other penalties. See “— Risks Related to Doing Business in China — Regulation and
censorship of information disseminated over the Internet in China may adversely affect our business and subject us
to liability for information linked to our websites.”

PRC advertising laws and regulations require advertisers, advertising operators and advertising distributors,
including online advertising publishers such as us, to ensure that the content of the advertisements they prepare or
distribute are fair and accurate and are in full compliance with applicable law. Violation of these laws or regulations
may result in penalties, including fines, confiscation of advertising fees, orders to cease dissemination of the
advertisements and orders to publish an advertisement correcting the misleading information. In circumstances
involving serious violations, the PRC government may force the violator to terminate its advertising operation or
even revoke its business license. Furthermore, advertisers, advertising operators or advertising distributors may be
subject to civil liability if they infringe on the legal rights and interests of third parties.

Under PRC advertising laws and regulations, we are obligated to monitor the advertising content posted on our
websites. In addition, where a special government review is required for specific categories of advertisements
before posting, we are obligated to confirm that such review has been performed and approval has been obtained.
Our reputation could be hurt and our results of operations could be adversely affected if advertisements shown on
our websites are provided to us by our advertising clients in violation of relevant PRC advertising laws and
regulations, or if the supporting documentation and government approvals provided to us by our advertising clients
in connection with such advertising content are not complete.

Our P4P services are not subject to PRC advertising laws and regulations because PRC laws and regulations
currently do not classify P4P services as a form of online advertising. However, we cannot assure you that the PRC
government will not classify P4P as a form of online advertising in the future. If P4P services are classified as a form
of online advertising, we would have to examine the content of our P4P customers’ listings on our websites, as
required by PRC advertising laws, and such examinations could be very burdensome. Moreover, we have been and
in the future may again be subject to claims or negative publicity based on the results in our paid search listings. In
November 2008, China Central Television, or CCTV, the largest state-owned television network in China, reported
that we had been including websites of medical companies that do not hold proper licenses in our paid search
listings for some popular medical terms. Shortly after the report, we removed paid search listings of certain
customers, particularly medical and pharmaceutical customers without documentations on file with us, and later
allowed a large portion of those customers to resume access to our P4P platform after their relevant documentations
were provided to and reviewed by us. The removal of these questionable paid search listings adversely affected our
revenues for the fourth quarter of 2008. Claims and negative publicity based on the results in our paid search
listings, regardless of their merit, may divert management attention, severely disrupt our operations, adversely
affect our results of operations and harm our reputation.

We may be subject to patent infringement claims with respect to our P4P platform.

Our technologies and business methods, including those relating to our pay-for-performance, or P4P, platform,
may be subject to third-party claims or rights that limit or prevent their use. In June 2005, we applied for a patent in
China for our P4P platform, but our application was rejected on the ground that it is not patentable. Overture
Services Inc., or Overture, a subsidiary of Yahoo!, had applied for a patent in China relating to a P4P platform prior
to our patent application in China covering a P4P platform. Based on a search conducted by an intellectual property
agency in China, as of March 23, 2009, no patent covering a P4P platform had been issued in China. The application
and interpretation of China’s patent laws and the procedures and standards for granting patents in China are still
evolving and involve a certain degree of uncertainty. We cannot assure you that Overture or another party will not
obtain a patent in China relevant to P4P platforms that may result in potential infringement by our P4P platform.
Moreover, certain U.S.-based companies, including Overture, have been granted patents in the United States
relating to P4P platforms and similar business methods and related technologies. Based on publicly available
information, we are aware that Overture has brought patent infringement claims in the United States against third
parties, and while we believe that we are not subject to U.S. patent laws since we conduct our business operations

outside of the United States, we cannot assure you that U.S. patent laws would not be applicable to our business
operations, or that holders of patents relating to a P4P platform would not seek to enforce such patents against us in
the United States or China.

In addition, many parties are actively developing and seeking protection for Internet-related technologies,
including seeking patent protection. There may be patents issued or pending that are held by others that relate to
certain aspects of our technologies, products, business methods or services. Any patent infringement claims,
regardless of their merits, could be time-consuming and costly to us. If we were sued for patent infringement claims
and were found to infringe such patents and were not able to adopt non-infringing technologies, we may be severely
limited in our ability to operate our P4P platform, which would have a material adverse effect on our results of
operations and business prospects.

If we fail to keep up with rapid technological changes, our future success may be adversely affected.

The online marketing industry is subject to rapid technological changes. Our future success will depend on our
ability to respond to rapidly changing technologies, adapt our services to evolving industry standards and improve
the performance and reliability of our services. Our failure to adapt to such changes could harm our business. New
marketing media could also adversely affect us. For example, the number of people accessing the Internet through
devices other than personal computers, including mobile telephones and hand-held devices, has increased in recent
years. If we are slow to develop products and technologies that are more compatible with non-PC communications
devices, or if the products and services we develop for people accessing the Internet through non-PC commu-
nications devices do not meet their needs, we may not be able to capture a significant share of this increasingly
important market for media and other services. In addition, the widespread adoption of new Internet, networking or
telecommunications technologies or other technological changes could require substantial expenditures to modify
or adapt our products, services or infrastructure. If we fail to keep up with rapid technological changes to remain
competitive in our rapidly evolving industry, our future success may be adversely affected.

Our business may be adversely affected by third-party software applications or practices that interfere
with our receipt of information from, or provision of information to, our users, which may impair our
users’ experience.

Our business may be adversely affected by third-party malicious or unintentional software applications that
make changes to our users’ computers and interfere with our products and services. These software applications
may change our users’ Internet experience by hijacking queries to our websites, altering or replacing our search
results, or otherwise interfering with our ability to connect with our users. The interference often occurs without
disclosure to or consent from users, resulting in a negative experience that users may associate with Baidu.com.
These software applications may be difficult or impossible to remove or disable, may reinstall themselves and may
circumvent other applications’ efforts to block or remove them. In addition, our business may be adversely affected
by the practices of third-party website owners which interfere with our ability to crawl and index their web pages.
The ability to provide a superior user experience is critical to our success. If we are unable to successfully combat
third-party software applications that interfere with our products and services, our reputation may be harmed. If a
significant number of website owners prevent us from indexing and including their web pages in our search results,
the quality of our search results may be impaired.

We are subject to risks and uncertainties faced by companies with limited operating history in a rapidly
evolving industry.

We commenced operations in 2000 and first achieved profitability in the quarter ended March 31, 2004.
Accordingly, you should consider our future prospects in light of the risks and uncertainties experienced by
companies with limited operating history in evolving industries such as the Internet industry in China. Some of
these risks and uncertainties relate to our ability to:

(cid:129) maintain our leading position in the Chinese language Internet search market;

(cid:129) offer new and innovative products to attract and retain a larger user base;

(cid:129) upgrade our technology to support increased traffic and expanded services.

If we are unsuccessful in addressing any of these risks and uncertainties, our business may be materially and

adversely affected.

Our historical growth rate may not be indicative of our future growth rate.

We have experienced substantial growth in recent years. Our total revenues and net income grew at a
compound annual growth rate, or CAGR, of 128.4% and 205.7%, respectively, from 2004 to 2008. Our growth was
driven in part by the growth in China’s Internet and online marketing industries, which may not be indicative of
future growth or be sustainable. We cannot assure you that our past growth rate is indicative of our future growth
rate.

Our operating results may fluctuate, which makes our results difficult to predict and could cause our
results to fall short of expectations.

Our operating results may fluctuate as a result of a number of factors, many of which are outside of our control.
For these reasons, comparing our operating results on a period-to-period basis may not be meaningful, and you
should not rely on our past results as an indication of our future performance. Our quarterly and annual revenues and
costs and expenses as a percentage of our revenues may be significantly different from our historical or projected
rates. Our operating results in future quarters may fall below expectations. Any of these events could cause the price
of our ADSs to fall. Any of the risk factors listed in this “Risk Factors” section and, in particular, the following risk
factors, could cause our operating results to fluctuate from quarter to quarter:

(cid:129) general economic conditions in China and economic conditions specific to the Internet, Internet search and

online marketing;

(cid:129) our ability to continue to attract users to our website;

(cid:129) our ability to attract additional customers and increase spending per customer;

(cid:129) the announcement or introduction of new or enhanced products and services by us or our competitors;

(cid:129) the amount and timing of operating costs and capital expenditures related to the maintenance and expansion

of our businesses, operations and infrastructure;

(cid:129) the results of our acquisitions of, or investments in, other businesses or assets;

(cid:129) PRC regulations or actions pertaining to activities on the Internet, including MP3 music, news, gambling,

online games and other forms of entertainment;

(cid:129) unforeseen events, such as negative publicity arising from reports by influential media outlets and other

sources; and

(cid:129) geopolitical events, natural disasters or epidemics such as war, threat of war, avian influenza, Severe Acute

Respiratory Syndrome, or SARS, or other public health epidemics.

Because of our limited operating history and our rapidly growing business, our historical operating results may
not be useful to you in predicting our future operating results. Our user traffic tends to be seasonal. For example, we
generally experience less user traffic during public holidays and other special event periods in China. In addition,
advertising and other marketing spending in China has historically been cyclical, reflecting overall economic
conditions as well as budgeting and buying patterns. Our rapid growth has lessened the impact of the cyclicality and
seasonality of our business. As we continue to grow, we expect that the cyclicality and seasonality in our business
may cause our operating results to fluctuate.

The global financial and economic crisis, particularly the slowdown in the Chinese economy, may
adversely affect our business, results of operations and financial condition.

The global financial markets have experienced significant disruptions recently, and most of the world’s major
economies have entered into recession. The Chinese economy has also slowed down significantly since the second
half of 2008 and this trend may continue for the rest of 2009 and beyond. Since we derive most of our revenues from
online marketing customers in China, any prolonged slowdown in the Chinese economy may have negative impact
on our business, operating results and financial condition in a number of ways. For example, our customers may
decrease or delay spending with us, while we may have difficulty expanding our customer base fast enough, or at all,
to offset the impact of decreased spending by our existing customers. In addition, to the extent we offer credit to any
customer and such customer experiences financial difficulties due to the economic slowdown, we could have
difficulty collecting payment from such customer.

We may not be able to prevent others from unauthorized use of our intellectual property, which could
harm our business and competitive position.

We rely on a combination of copyright, trademark and trade secret laws, as well as nondisclosure agreements
and other methods to protect our intellectual property rights. The protection of intellectual property rights in China
may not be as effective as those in the United States or other countries. The steps we have taken may be inadequate
to prevent the misappropriation of our technology. Reverse engineering, unauthorized copying or other misap-
propriation of our technologies could enable third parties to benefit from our technologies without paying us.
Moreover, unauthorized use of our technology could enable our competitors to offer products and services that are
comparable to or better than ours, which could harm our business and competitive position. From time to time, we
may have to enforce our intellectual property rights through litigation. Such litigation may result in substantial costs
and diversion of resources and management attention.

Because we rely to a large extent on distributors in providing our P4P services, our failure to retain key
distributors or attract additional distributors could materially and adversely affect our business. Moreover,
there is no assurance that our direct sales model in some key geographic markets will continue to be
successful.

Online marketing is at an early stage of development in China and is not as widely accepted by or available to
businesses in China as in the United States. As a result, we rely to a large extent on a nationwide distribution
network of third-party distributors for our sales to, and collection of payment from, our P4P customers. If our
distributors do not provide quality services to our P4P customers or otherwise breach their contracts with our P4P
customers, we may lose customers and our results of operations may be materially and adversely affected. We do
not have long-term agreements with any of our distributors, including our key distributors, and cannot assure you
that we will continue to maintain favorable relationships with them. If we fail to retain our key distributors or attract
additional distributors on terms that are commercially reasonable, our business and results of operations could be
materially and adversely affected.

We have transitioned to using our direct sales force to serve our P4P customers in some key geographic
markets, including Shanghai, Beijing and selected cities in Guangdong Province, including Guangzhou, Shenzhen
and Dongguan. There is no assurance that our direct sales model in those markets will continue to be successful. If

we fail to maintain an adequate direct sales force, retain existing customers and continue to attract new customers in
those markets, our business, results of operations and prospects could be materially and adversely affected.

We rely on our Baidu Union members for a significant portion of our revenues. If we fail to retain
existing Baidu Union members or attract additional members, our revenue growth and profitability may
be adversely affected.

We pay our Baidu Union members a portion of our revenues generated from click-throughs by users of our
Baidu Union members’ property. We consider our Baidu Union critical to the future growth of our revenues. Some
of our Baidu Union members, however, may compete with us in one or more areas of our business. Therefore, they
may decide in the future to terminate their relationships with us. If our Baidu Union members decide to use a
competitor’s or their own Internet search services, our user traffic may decline, which may adversely affect our
revenues. If we fail to attract additional Baidu Union members, our revenue growth may be adversely affected. In
addition, if we have to share a larger portion of our revenues to retain existing Baidu Union members or attract
additional members, our profitability may be adversely affected.

Our strategy of acquiring complementary businesses, assets and technologies may fail.

As part of our business strategy, we have pursued, and intend to continue to pursue, selective strategic
acquisitions of businesses, assets and technologies that complement our existing business. For example, we
acquired certain online application platform businesses and customer lists from distributors in 2006 and 2007. We
may make other acquisitions in the future if suitable opportunities arise. Acquisitions involve uncertainties and
risks, including:

(cid:129) potential ongoing financial obligations and unforeseen or hidden liabilities;

(cid:129) failure to achieve the intended objectives, benefits or revenue-enhancing opportunities;

(cid:129) costs and difficulties of integrating acquired businesses and managing a larger business; and

(cid:129) diversion of resources and management attention.

Our failure to address these risks successfully may have a material adverse effect on our financial condition
and results of operations. Any such acquisition may require a significant amount of capital investment, which would
decrease the amount of cash available for working capital or capital expenditures. In addition, if we use our equity
securities to pay for acquisitions, we may dilute the value of our ADSs and the underlying ordinary shares. If we
borrow funds to finance acquisitions, such debt instruments may contain restrictive covenants that could, among
other things, restrict us from distributing dividends. Such acquisitions may also generate significant amortization
expenses related to intangible assets.

Our recent expansion into the Japanese market may not be successful.

We formally launched our Japanese search service in January 2008, after completing a 10-month Beta test for
the service. Therefore, we only have limited experience operating in the Japanese market. Moreover, our Japan
operation has incurred operating losses since its inception in December 2006, and there is no assurance when it will
become profitable, if at all. Additional future losses in our Japan operation could have a material adverse effect on
our overall results of operations.

The Japanese search market is highly competitive and currently is dominated by two companies, Yahoo! and
Google. These companies have significantly greater financial resources, longer operating history and more
experience in the Japanese search market than we do. Moreover, other local providers of competing search
services may also have a substantial advantage over us in attracting users due to more established branding in Japan,
greater knowledge with respect to the tastes and preferences of Japanese users and their focus on the Japanese
market. If we cannot compete successfully with these competitors in the Japanese language search market, our
business in Japan could be adversely affected.

In addition to uncertainty about our ability to compete successfully in Japan, there are certain risks inherent in

doing business internationally, including:

(cid:129) trade barriers and changes in trade regulations;

(cid:129) difficulties in developing, staffing and simultaneously managing a foreign operation as a result of distance,

language and cultural differences;

(cid:129) stringent local labor laws and regulations;

(cid:129) longer customer payment cycles;

(cid:129) currency exchange rate fluctuations;

(cid:129) political or social unrest or economic instability;

(cid:129) seasonal volatility in business activity;

(cid:129) risks related to government regulations or required compliance with local laws and changes in such laws and

regulations; and

(cid:129) potentially adverse tax consequences.

One or more of these factors could harm our Japanese operations and consequently, could harm our overall

operating results.

Our success depends on the continuing and collaborative efforts of our senior management team and
other key personnel, and our business may be harmed if we lose their services.

Our future success depends heavily upon the continuing services of the members of our senior management
team, in particular our chairman and chief executive officer, Robin Yanhong Li. If one or more of our senior
executives or other key personnel are unable or unwilling to continue in their present positions, we may not be able
to replace them easily or at all, and our business may be disrupted and our financial condition and results of
operations may be materially and adversely affected. Competition for senior management and key personnel is
intense, the pool of qualified candidates is very limited, and we may not be able to retain the services of our senior
executives or key personnel, or attract and retain high-quality senior executives or key personnel in the future. In
addition, most of our current senior executives joined us in 2008 and have worked together only for a relatively short
period of time. As a result, it may be difficult for you to evaluate how well our senior executives will work together
as a team.

If any member of our senior management team or any of our other key personnel joins a competitor or forms a
competing company, we may lose customers, distributors, know-how and key professionals and staff members.
Each of our executive officers and key employees has entered into an employment agreement with us, containing
confidentiality and non-competition provisions. If any disputes arise between any of our senior executives or key
personnel and us, we cannot assure you the extent to which any of these agreements may be enforced.

We rely on highly skilled personnel and, if we are unable to retain or motivate them or hire qualified
personnel, we may not be able to grow effectively.

Our performance and future success depends on the talents and efforts of highly skilled individuals. We will
need to continue to identify, hire, develop, motivate and retain highly skilled personnel for all areas of our
organization. Competition in our industry for qualified employees is intense. Our continued ability to compete
effectively depends on our ability to attract new employees and to retain and motivate our existing employees.

As competition in our industry intensifies, it may be more difficult for us to hire, motivate and retain highly
skilled personnel. If we do not succeed in attracting additional highly skilled personnel or retaining or motivating
our existing personnel, we may be unable to grow effectively.

If we are unable to adapt or expand our existing technology infrastructure to accommodate greater traffic
or additional customer requirements, our business may be harmed.

Our Baidu.com website regularly serves a large number of users and customers and delivers a large number of
daily page views. Our technology infrastructure is highly complex and may not provide satisfactory service in the
future, especially as the number of customers using our P4P services increases. We may be required to upgrade our
technology infrastructure to keep up with the increasing traffic on our websites, such as increasing the capacity of
our hardware servers and the sophistication of our software. If we fail to adapt our technology infrastructure to
accommodate greater traffic or customer requirements, our users and customers may become dissatisfied with our
services and switch to our competitors’ websites, which could harm our business.

If we fail to detect fraudulent click-through, we could lose the confidence of our customers and our
revenues could decline.

We are exposed to the risk of click-through fraud on our paid search results. Click-through fraud occurs when a
person clicks paid search results for a reason other than to view the underlying content of search results. If we find
evidence of past fraudulent clicks, we may have to issue refunds to our customers. If we fail to detect fraudulent
clicks or otherwise are unable to prevent this fraudulent activity, the affected customers may experience a reduced
return on their investment in our online marketing services and lose confidence in the integrity of our systems. If this
happens, we may be unable to retain existing customers and attract new customers for our online marketing services
and our online marketing revenues could decline. In addition, affected customers may also file legal actions against
us claiming that we have over-charged or failed to refund them. Any such claims or similar claims, regardless of
their merits, could be time-consuming and costly to us and could also adversely affect our brand image and our
customers’ confidence in the integrity of our systems.

The successful operation of our business depends upon the performance and reliability of the Internet
infrastructure and fixed telecommunications networks in China.

Our business depends on the performance and reliability of the Internet infrastructure in China. Almost all
access to the Internet is maintained through state-owned telecommunication operators under the administrative
control and regulatory supervision of the Ministry of Industry and Information Technology, or the MIIT. In addition,
the national networks in China are connected to the Internet through international gateways controlled by the PRC
government. These international gateways are the only channels through which a domestic user can connect to the
Internet. We cannot assure you that a more sophisticated Internet infrastructure will be developed in China. We may
not have access to alternative networks in the event of disruptions, failures or other problems with China’s Internet
infrastructure. In addition, the Internet infrastructure in China may not support the demands associated with
continued growth in Internet usage.

We also rely on China Telecommunications Corporation, or China Telecom, China United Network Com-
munications Group Company Limited, or China Unicom, and China Mobile Communications Corporation, or
China Mobile, to provide us with data communications capacity primarily through local telecommunications lines
and Internet data centers to host our servers. We do not have access to alternative services in the event of disruptions,
failures or other problems with the fixed telecommunications networks of China Telecom, China Unicom and China
Mobile, or if these companies otherwise fail to provide such services. In July 2008, due to power failures at a China
Telecom Internet data center that hosted our servers, we were unable to provide service for approximately five
hours. Any unscheduled service interruption could damage our reputation and result in a decrease in our revenues.
Furthermore, we have no control over the costs of the services provided by China Telecom, China Unicom and
China Mobile. If the prices that we pay for telecommunications and Internet services rise significantly, our gross
margins could be adversely affected. In addition, if Internet access fees or other charges to Internet users increase,
our user traffic may decrease, which in turn may harm our revenues.

Interruption or failure of our information technology and communications systems could impair our
ability to effectively provide our products and services, which could damage our reputation and harm our
operating results.

Our ability to provide our products and services depends on the continuing operation of our information
technology and communications systems. Any damage to or failure of our systems could interrupt our service.
Service interruptions could reduce our revenues and profits, and damage our brand if our system is perceived to be
unreliable. Our systems are vulnerable to damage or interruption as a result of terrorist attacks, war, earthquakes,
floods, fires, power loss, telecommunications failures, computer viruses, interruptions in access to our websites
through the use of “denial of service” or similar attacks, hacking or other attempts to harm our systems, and similar
events. Our servers, which are hosted at third-party Internet data centers, are also vulnerable to break-ins, sabotage
and vandalism. Some of our systems are not fully redundant, and our disaster recovery planning does not account for
all possible scenarios. The occurrence of a natural disaster or a closure of an Internet data center by a third-party
provider without adequate notice could result in lengthy service interruptions.

In September 2006, our Internet search services were disrupted for approximately half an hour as a result of
attacks to our Baidu.com website from unknown hackers. If we experience frequent or persistent system failures on
our websites, our reputation and brand could be permanently harmed. The steps we plan to take to increase the
reliability and redundancy of our systems are expensive, reduce our operating margin and may not be successful in
reducing the frequency or duration of service interruptions.

Our business could be adversely affected if our software contains bugs.

Our online systems, including our websites, could contain undetected errors or “bugs” that could adversely
affect their performance. We regularly update and enhance our website and our other online systems. The
occurrence of errors in any of these may cause us to lose market share, damage our reputation and brand name,
and materially and adversely affect our business.

Concerns about the security of electronic commerce transactions and confidentiality of information on
the Internet may reduce use of our network and impede our growth.

A significant barrier to electronic commerce and communications over the Internet in general has been a public
concern over security and privacy, including the transmission of confidential information. If these concerns are not
adequately addressed, they may inhibit the growth of the Internet and other online services generally, especially as a
means of conducting commercial transactions. If a well-publicized Internet breach of security were to occur,
general Internet usage could decline, which could reduce traffic to our destination websites and impede our growth.

If we fail to maintain an effective system of internal control over financial reporting, we may lose investor
confidence in the reliability of our financial statements.

We are subject to reporting obligations under the U.S. securities laws. The SEC, as required by Section 404 of
the Sarbanes-Oxley Act of 2002, adopted rules requiring every public company to include a management report on
such company’s internal control over financial reporting in its annual report, which contains management’s
assessment of the effectiveness of the company’s internal control over financial reporting. In addition, an
independent registered public accounting firm must attest to and report on the effectiveness of the company’s
internal control over financial reporting. We have been subject to these requirements since the fiscal year ended
December 31, 2006.

Our management has concluded that our internal control over financial reporting is effective as of Decem-
ber 31, 2008. See “Item 15. Control and Procedures.” Our independent registered public accounting firm has issued
an attestation report, which has concluded that our internal control over financial reporting is effective in all
material aspects. However, if we fail to maintain effective internal control over financial reporting in the future, our
management and our independent registered public accounting firm may not be able to conclude that we have
effective internal control over financial reporting at a reasonable assurance level. This could in turn result in the loss
of investor confidence in the reliability of our financial statements and negatively impact the trading price of our

ADSs. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs, management
time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We have limited business insurance coverage.

The insurance industry in China is still at an early stage of development. Insurance companies in China offer
limited business insurance products. We do not have any business liability or disruption insurance coverage for our
operations in China. Any business disruption may result in our incurring substantial costs and the diversion of our
resources.

Risks Related to Our Corporate Structure

PRC laws and regulations governing our businesses and the validity of certain of our contractual
arrangements are uncertain. If we are found to be in violation, we could be subject to sanctions. In
addition, changes in such PRC laws and regulations or changes in interpretations thereof may materially
and adversely affect our business.

There are substantial uncertainties regarding the interpretation and application of PRC laws and regulations,
including, but not limited to, the laws and regulations governing our business, or the enforcement and performance
of our contractual arrangements with our affiliated Chinese entities, Baidu Netcom Science Technology Co., Ltd.,
or Baidu Netcom, Beijing Perusal Technology Co., Ltd., or Beijing Perusal, and Beijing BaiduPay Science and
Technology Co., Ltd., or BaiduPay, and their shareholders. We and our PRC subsidiaries, Baidu Online Network
Technology (Beijing) Co., Ltd., or Baidu Online, Baidu (China) Co., Ltd., or Baidu China and Baidu.com Times
Technology (Beijing) Co. Ltd., or Baidu Times, are considered foreign persons or foreign-invested enterprises
under PRC law. As a result, we and our PRC subsidiaries are subject to PRC legal restrictions on foreign ownership
of Internet and online advertising companies. These laws and regulations are relatively new and may be subject to
change, and their official interpretation and enforcement may involve substantial uncertainty. New laws and
regulations that affect existing and proposed future businesses may also be applied retroactively.

The PRC government has broad discretion in dealing with violations of laws and regulations, including levying
fines, revoking business and other licenses and requiring actions necessary for compliance. We cannot predict the
effect of the interpretation of existing or new PRC laws or regulations on our businesses. We cannot assure you that
our current ownership and operating structure would not be found in violation of any current or future PRC laws or
regulations. As a result, we may be subject to sanctions, including fines, and could be required to restructure our
operations or cease to provide certain services. Any of these or similar actions could significantly disrupt our
business operations or restrict us from conducting a substantial portion of our business operations, which could
materially and adversely affect our business, financial condition and results of operations.

If the PRC government were to classify P4P services as a form of online advertising or as part of Internet
content provider services, we may have to conduct our P4P business through Baidu Netcom, which would
increase our effective tax rate, and we might be subject to sanctions and required to pay delinquent taxes.

PRC laws and regulations do not currently classify P4P as a form of online advertising or as part of ICP
services requiring an ICP license. We conduct our P4P business through our subsidiaries in the PRC, none of which
has the qualification to operate online advertising business or holds an ICP license. However, we cannot assure you
that the PRC government will not classify P4P as a form of online advertising or as part of ICP services in the future.
If new regulations characterize P4P as a form of online advertising or as part of ICP services, we may have to
conduct our P4P business through Baidu Netcom, which is qualified to operate online advertising business and
holds an ICP license. This would increase our consolidated effective tax rate for two reasons. First, advertising
revenues generated by Baidu Netcom are subject to a 3% construction fee for culture undertakings in addition to the
5% business tax. Second, Baidu Netcom is currently subject to a 25% enterprise income tax rate, as compared to the
lower preferential enterprise income tax rates that our PRC subsidiaries are subject to as of the date of this annual
report. See “Item 5A. Operating and Financial Review and Prospects — Operating Results — Taxation” for more
information on PRC business and enterprise income tax as applicable to our subsidiaries and affiliated entities in the
PRC. Moreover, if the change in classification of P4P were to be retroactively applied, we might be subject to

NEXT PCN: 022.00.00.00 -- Page is valid, no graphics

BOM  H03242  021.00.00.00  8

sanctions, including payment of delinquent taxes and fines. In addition, the classification of P4P as a form of online
advertising could subject us to an obligation to monitor the content of listings of our P4P customers on our websites
and the associated risks. See “— Risks Related to Our Businesses — We may be subject to claims based on the
content found on our websites or the results in our paid search listings.” Any change in the classification of P4P by
the PRC government may significantly disrupt our operations and materially and adversely affect our business,
results of operations and financial conditions.

We may be adversely affected by complexity, uncertainties and changes in PRC regulation of Internet
business and companies, including limitations on our ability to own key assets such as our websites.

The PRC government extensively regulates the Internet industry, including foreign ownership of, and the
licensing and permit requirements pertaining to, companies in the Internet industry. These Internet-related laws and
regulations are relatively new and evolving, and their interpretation and enforcement involve significant uncer-
tainty. As a result, in certain circumstances it may be difficult to determine what actions or omissions may be
deemed to be violations of applicable laws and regulations. Issues, risks and uncertainties relating to PRC
government regulation of the Internet industry include, but are not limited to, the following:

(cid:129) We only have contractual control over our websites. We do not own the websites due to the restriction of
foreign investment in businesses providing value-added telecommunication services in China, including
online information services.

(cid:129) There are uncertainties relating to the regulation of the Internet business in China, including evolving
licensing practices. This means that permits, licenses or operations at some of our companies may be subject
to challenge, or we may not be able to obtain or renew certain permits or licenses, including without
limitation an Internet news license issued by the State Council News Office, an Internet culture business
permit issued by the Ministry of Culture and an audio/video program transmission license issued by the State
Administration of Radio, Film and Television. This may significantly disrupt our business, or subject us to
sanctions, requirements to increase capital or other conditions or enforcement, or compromise enforceability
of related contractual arrangements, or have other harmful effects on us.

(cid:129) Certain PRC government authorities have stated publicly that they are in the process of promulgating new
laws and regulations that will regulate Internet activities, including online advertising and online payment.
Other aspects of our online operations may be regulated in the future. If these new laws and regulations are
promulgated, additional licenses may be required for our online operations. If our operations do not comply
with these new regulations at the time they become effective, or if we fail to obtain any licenses required
under these new laws and regulations, we could be subject to penalties.

In July 2006, the MIIT (then known as the Ministry of Information Industry) issued the Notice of the Ministry
of Information Industry on Intensifying the Administration of Foreign Investment in Value-added Telecommu-
nications Services, or the July 2006 Notice. The July 2006 Notice prohibits domestic telecommunication services
providers from leasing, transferring or selling telecommunications business operating licenses to any foreign
investor in any form, or providing any resources, sites or facilities to any foreign investor for their illegal operation
of a telecommunications business in China. According to the July 2006 Notice, either the holder of a value-added
telecommunication business operating license or its shareholders must directly own the domain names and
trademarks used by such license holders in their provision of value-added telecommunication services. The July
2006 Notice also requires each license holder to have the necessary facilities, including servers, for its approved
business operations and to maintain such facilities in the regions covered by its license.

Baidu Netcom, our PRC affiliated entity that holds the ICP license necessary to conduct our business in China,
received a letter from the MIIT requiring self-assessment and responded timely. In order to comply with the July
2006 Notice, we have transferred certain domain names primarily used in our business to Baidu Netcom and Beijing
Perusal, respectively. In addition, we are in the process of transferring certain trademarks, including pending
trademark applications made by Baidu Online, to Baidu Netcom, Beijing Perusal and BaiduPay, respectively.

As we enter into new businesses, we may encounter additional regulatory uncertainties. For example, it
remains unclear whether the provision of online payment services by BaiduPay will require BaiduPay to apply for a

21

ACEBOWNE OF MONTREAL, INC

value-added telecommunications business operating license for “online data processing and transaction processing
businesses” as provided in the Catalog of Telecommunications Businesses promulgated by the MIIT.

In addition, there are currently no regulations requiring a non-financial institution that provides third-party
online payment services, such as BaiduPay, to apply for licensing from the People’s Bank of China, or the PBOC.
However, in 2005, the PBOC published Draft Measures Concerning the Administration of Payment and Settlement
Organizations, or the Draft Measures, for public comment. According to the Draft Measures, non-financial
institutions engaging in activities related to payment and settlement services, including services such as providing
electronic instructions and calculations to financial institutions, individuals and other entities, shall be required to
obtain a license from the PBOC or its relevant branches in order to provide payment and settlement services. The
Draft Measures have not yet taken effect. If the Draft Measures are officially adopted by the PBOC and become
applicable to BaiduPay, it may be necessary for us to obtain approvals or licenses to engage in our online payment
business. We cannot assure you that we will be able to obtain these approvals or licenses.

Furthermore, in December 2007, the Standing Committee of Beijing Municipal People’s Congress adopted
Beijing Municipal Regulations on Promotion of Informatization, which provide that any individual or enterprise
that conducts business operations through the Internet shall obtain a business license and/or other necessary licenses
prior to operation. The operator of an online marketplace shall be responsible for checking such individual or
enterprise’s licenses. In July 2008, the Beijing Administration for Industry and Commerce, or Beijing AIC,
promulgated certain rules for implementing the above mentioned regulations. According to these rules, any
individual or enterprise failing to obtain a business license may be prohibited from doing business on an
e-commerce marketplace operating in Beijing, such as Baidu Youa, and violation of these rules may lead to
penalties on either the individual/enterprise or the operator of the e-commerce marketplace. Substantial uncer-
tainties exist in terms of the implementation of these rules, and there are very few public reports regarding actions
taken by the Beijing AIC against any violators in this regard. We cannot predict to what extent these rules will affect
our business operations or future strategy.

The interpretation and application of existing PRC laws, regulations and policies and possible new laws,
regulations or policies relating to the Internet industry have created substantial uncertainties regarding the legality
of existing and future foreign investments in, and the businesses and activities of, Internet businesses in China,
including our business.

In order to comply with PRC laws and regulations limiting foreign ownership of Internet and online
advertising businesses, we conduct our ICP and online advertising businesses through our consolidated
affiliated entities in China by means of contractual arrangements. If the PRC government determines that
these contractual arrangements do not comply with applicable regulations, our business could be
adversely affected.

The PRC government restricts foreign investment in Internet and online advertising businesses. Accordingly, we
operate our websites and our online advertising business in China through Baidu Netcom, a company wholly-owned
by our chairman, chief executive officer and co-founder Robin Yanhong Li and our co-founder Eric Yong Xu, Beijing
Perusal, a company wholly-owned by two individuals designated by our company, and BaiduPay, a company
wholly-owned by Baidu Netcom and an individual designated by our company. All of the individual shareholders of
Baidu Netcom, Beijing Perusal and BaiduPay are PRC citizens. Baidu Netcom and Beijing Perusal hold the licenses
and approvals necessary to operate our websites and our online advertising business in China. We have contractual
arrangements with Baidu Netcom, Beijing Perusal, BaiduPay and their individual shareholders that allow us to
substantially control Baidu Netcom, Beijing Perusal and BaiduPay. We cannot assure you, however, that we will be
able to enforce these contracts.

Although we believe we comply with current PRC regulations, we cannot assure you that the PRC government
would agree that these operating arrangements comply with PRC licensing, registration or other regulatory
requirements, with existing policies or with requirements or policies that may be adopted in the future. If the PRC
government determines that we do not comply with applicable law, it could revoke our business and operating
licenses, require us to discontinue or restrict our operations, restrict our right to collect revenues, block our websites,
require us to restructure our operations, impose additional conditions or requirements with which we may not be

able to comply, impose restrictions on our business operations or on our customers, or take other regulatory or
enforcement actions against us that could be harmful to our business.

Our contractual arrangements with our consolidated affiliated entities in China and their individual
shareholders may not be as effective in providing control over these entities as direct ownership.

Since PRC law restricts foreign equity ownership in Internet and online advertising companies in China, we
operate our ICP and online advertising businesses through our consolidated affiliated entities in China,
Baidu Netcom, Beijing Perusal and BaiduPay. We have no equity ownership interest in any of these entities
and must rely on contractual arrangements to control and operate such businesses. These contractual arrangements
may not be as effective in providing control over these entities as direct ownership. For example, Baidu Netcom,
Beijing Perusal or BaiduPay could fail to take actions required for our business or fail to maintain our websites
despite its contractual obligation to do so. If they fail to perform under their respective agreements with us, we may
have to rely on legal remedies under PRC law, which may not be effective. In addition, we cannot assure you that
any of their respective individual shareholders would always act in our best interests.

The new PRC Property Rights Law may affect the perfection of the pledge in our equity pledge
agreements with our consolidated affiliated entities and their individual shareholders.

Under the equity pledge agreements among Baidu Online and our consolidated affiliated entities,
Baidu Netcom, Beijing Perusal and BaiduPay, and their respective individual shareholders, the individual share-
holders of Baidu Netcom, Beijing Perusal and BaiduPay have pledged all of their equity interests therein to Baidu
Online by recording the pledge on the shareholder registers of the respective entities. However, according to the
PRC Property Rights Law, which became effective as of October 1, 2007, a pledge is not effective without being
registered with the relevant local administration for industry and commerce. The State Administration for Industry
and Commerce, or SAIC, and the Beijing AIC have adopted registration procedures with respect to the registration
of equity interest pledge according to the Property Rights Law. However, it remains unclear under the PRC Property
Rights Law whether Baidu Netcom and Beijing Perusal are required to register their pledges, which were created
before October 1, 2007. Baidu Netcom, Beijing Perusal and BaiduPay are in the process of registering the equity
pledge with the Beijing AIC. We cannot assure you that they will be able to register the pledge. If they are unable to
do so, the pledges may be deemed ineffective under the PRC Property Rights Law. If any individual shareholder of
Baidu Netcom, Beijing Perusal or BaiduPay breaches his or her obligations under the agreement with Baidu Online,
there is a risk that Baidu Online may not be able to successfully enforce the pledge and would need to resort to legal
proceedings to enforce its contractual rights.

Our contractual arrangements with our consolidated affiliated entities in China may result in adverse tax
consequences to us.

As a result of our corporate structure and the contractual arrangements between Baidu Online and each of our
consolidated affiliated entities in China, we are effectively subject to the 5% PRC business tax on both revenues
generated by Baidu Netcom’s, Beijing Perusal’s and BaiduPay’s operations in China and revenues derived from
Baidu Online’s contractual arrangements with these entities. Moreover, we would be subject to adverse tax
consequences if the PRC tax authorities were to determine that the contracts between Baidu Online and these
entities were not on an arm’s length basis and therefore constitute a favorable transfer pricing. As a result, the PRC
tax authorities could request that Baidu Netcom, Beijing Perusal and BaiduPay adjust their taxable income upward
for PRC tax purposes. Such a pricing adjustment could adversely affect us by increasing Baidu Netcom’s, Beijing
Perusal’s and BaiduPay’s tax expenses without reducing Baidu Online’s tax expenses, which could subject Baidu
Netcom, Beijing Perusal and BaiduPay to interest due on late payments and other penalties for under-payment of
taxes.

The new PRC Enterprise Income Tax Law became effective on January 1, 2008. This new tax law specifies
special adjustments to taxation. In particular, an enterprise must submit its annual tax return together with
information on related party transactions to the tax authorities. The tax authorities may impose reasonable
adjustments on taxation if they have identified any related party transactions that are inconsistent with arm’s-
length principles.

We may have exposure to greater than anticipated tax liabilities.

We are subject to income tax, business tax and other taxes in many provinces and cities in China and our tax
structure is subject to review by various local tax authorities. The determination of our provision for income tax and
other tax liabilities requires significant judgment and in the ordinary course of our business, there are many
transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates
are reasonable, the ultimate decisions by the relevant tax authorities may differ from the amounts recorded in our
financial statements and may materially affect our financial results in the period or periods for which such
determination is made.

The principal shareholder of Baidu Netcom has potential conflicts of interest with us, which may
adversely affect our business.

Robin Yanhong Li, our chairman and chief executive officer, is also the principal shareholder of Baidu Netcom.
Conflicts of interests between his duties to our company and Baidu Netcom may arise. As Mr. Li is a director and
executive officer of our company, he has a duty of loyalty and care to us under Cayman Islands law when there are
any potential conflicts of interests between our company and Baidu Netcom. Additionally, Mr. Li has executed an
irrevocable power of attorney to appoint the individual designated by us to be his attorney-in-fact to vote on his
behalf on all Baidu Netcom matters requiring shareholder approval. We cannot assure you, however, that when
conflicts of interest arise, Mr. Li will act completely in our interests or that conflicts of interests will be resolved in
our favor. In addition, Mr. Li could violate his employment agreement with us or his legal duties by diverting
business opportunities from us to others. If we cannot resolve any conflicts of interest between us and Mr. Li, we
would have to rely on legal proceedings, which could be expensive, time-consuming and result in the disruption of
our business.

Our corporate actions are substantially controlled by our principal shareholders and affiliated entities.

Our principal shareholders and their affiliated entities own more than a majority of our voting power due to our
dual-class ordinary share structure. These shareholders, acting individually or as a group, could exert substantial
influence over matters such as electing directors and approving mergers or other business combination transactions.
This concentration of voting power may also discourage, delay or prevent a change in control of our company,
which could deprive our shareholders of an opportunity to receive a premium for their shares as part of a sale of our
company and might reduce the price of our ADSs.

We may be unable to collect long-term loans to the shareholders of our consolidated affiliated entities in
China.

As of December 31, 2008, we had made long-term loans in an aggregate principal amount of
RMB100.0 million (US$14.7 million), RMB1.0 million (US$0.1 million) and RMB9.0 million (US$1.3 million)
to the individual shareholders of Baidu Netcom, Beijing Perusal and BaiduPay, respectively. We extended these
loans to enable the shareholders to fund the initial capitalization of Baidu Netcom, Beijing Perusal and BaiduPay,
respectively, and in the case of Baidu Netcom, subsequent increases in its registered capital. As of the date of this
annual report, all of the registered capital of our consolidated affiliated entities in China has been fully funded. We
may in the future provide additional loans to the individual shareholders of our consolidated affiliated entities in
China in connection with any increase in their capitalization to the extent necessary and permissible under
applicable law. Our ability to ultimately collect these loans will depend on the profitability of these consolidated
affiliated entities and their operational needs, which are uncertain.

Risks Related to Doing Business in China

Adverse changes in economic and political policies of the PRC government could have a material adverse
effect on the overall economic growth of China, which could adversely affect our business.

Most of our business operations are conducted in China. Accordingly, our results of operations, financial
condition and prospects are subject to a significant degree to economic, political and legal developments in China.
China’s economy differs from the economies of most developed countries in many respects, including with respect

24

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:15 NO MARKS 

NEXT PCN: 026.00.00.00 -- Page is valid, no graphics

BOM  H03242  025.00.00.00  8

to the amount of government involvement, level of development, growth rate, control of foreign exchange and
allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has
been uneven across different regions and among various economic sectors of China. The PRC government has
implemented various measures to encourage economic development and guide the allocation of resources. Some of
these measures benefit the overall PRC economy, but may also have a negative effect on us. For example, our
financial condition and results of operations may be adversely affected by government control over capital
investments or changes in tax regulations that are applicable to us. In addition, future measures to control the pace of
economic growth may cause a decrease in the level of economic activity in China, which in turn could adversely
affect our results of operations and financial condition.

Regulation and censorship of information disseminated over the Internet in China may adversely affect
our business and subject us to liability for information displayed on or linked to our websites.

The PRC government has adopted regulations governing Internet access and the distribution of news and other
information over the Internet. Under these regulations, Internet content providers and Internet publishers are
prohibited from posting or displaying over the Internet content that, among other things, violates PRC laws and
regulations, impairs the national dignity of China, or is reactionary, obscene, superstitious, fraudulent or defa-
matory. Failure to comply with these requirements may result in the revocation of licenses to provide Internet
content and other licenses and the closure of the concerned websites. In the past, failure to comply with such
requirements has resulted in the closure of certain websites. The website operator may also be held liable for such
censored information displayed on or linked to the website.

In addition, the MIIT has published regulations that subject website operators to potential liability for content
displayed on their websites and the actions of users and others using their systems, including liability for violations
of PRC laws and regulations prohibiting the dissemination of content deemed to be socially destabilizing. The
Ministry of Public Security has the authority to order any local Internet service provider to block any Internet
website at its sole discretion. From time to time, the Ministry of Public Security has stopped the dissemination over
the Internet of information which it believes to be socially destabilizing. The State Secrecy Bureau is also
authorized to block any website it deems to be leaking State secrets or failing to meet the relevant regulations
relating to the protection of State secrets in the dissemination of online information. Furthermore, we are required to
report any suspicious content to relevant governmental authorities, and to undergo computer security inspections. If
we fail to implement the relevant safeguards against security breaches, our websites may be shut down and our
business and ICP licenses may be revoked. In addition, Internet companies which provide bulletin board systems,
chat rooms or similar services must apply for specific approval from relevant authorities.

Although we attempt to monitor the content in our search results and on our online communities such as Baidu
Post Bar, we are not able to control or restrict the content of other Internet content providers linked to or accessible
through our websites, or content generated or placed on our Baidu Post Bar message boards or our other online
communities by our users. To the extent that PRC regulatory authorities find any content displayed on our websites
objectionable, they may require us to limit or eliminate the dissemination of such information on our websites. If
third-party websites linked to or accessible through our websites operate unlawful activities such as online
gambling on their websites, PRC regulatory authorities may require us to report such unlawful activities to relevant
authorities and to remove the links to such websites, or they may suspend or shut down the operation of such
websites. PRC regulatory authorities may also temporarily block access to certain websites for a period of time for
reasons beyond our control. Any of these actions may reduce our user traffic and adversely affect our business. In
addition, we may be subject to penalties for violations of those regulations arising from information displayed on or
linked to our websites, including a suspension or shutdown of our online operations.

Intensified government regulation of Internet cafes could restrict our ability to maintain or increase user
traffic to our website.

In April 2001, the PRC government began tightening its regulation of Internet cafes. In particular, a large
number of unlicensed Internet cafes have been closed. In addition, the PRC government has imposed higher capital
and facility requirements for the establishment of Internet cafes. Furthermore, the PRC government’s policy, which
encourages the development of a limited number of national and regional Internet cafe chains and discourages the

25

establishment of independent Internet cafes, may slow down the growth of Internet cafes. In June 2002, the Ministry
of Culture, together with other government authorities, issued a joint notice, and in February 2004, the SAIC issued
another notice, suspending the issuance of new Internet cafe licenses. In May 2007, the SAIC reiterated its position
not to register any new Internet cafes in 2007. So long as Internet cafes are one of the primary venues for our users to
access our websites, any reduction in the number, or any slowdown in the growth, of Internet cafes in China could
limit our ability to maintain or increase user traffic to our websites.

If our PRC subsidiaries Baidu Online and Baidu Times fail to maintain qualification as “high and new
technology enterprise” under the PRC Enterprise Income Tax Law, or if our PRC subsidiary Baidu China
fails to retain its 50% reduced rate tax holiday, or if our PRC subsidiaries declare and distribute
dividends to their respective offshore parent companies, we will be required to pay more taxes, which
could have a material adverse effect on our result of operations.

According to the PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1,
2008, as further clarified by subsequent tax regulations implementing the EIT Law, foreign-invested enterprises and
domestic enterprises are subject to EIT at a uniform rate of 25%. The EIT rate of enterprises established before
March 16, 2007 that were eligible for preferential tax rates according to then effective tax laws and regulations will
gradually transition to the uniform 25% EIT rate by January 1, 2013. In addition, certain enterprises may still benefit
from a preferential tax rate of 15% under the EIT Law if they qualify as “high and new technology enterprises
strongly supported by the State,” subject to certain general factors described in the EIT Law and the related
regulations.

In December 2008, our PRC subsidiaries Baidu Online and Baidu Times were designated by the Beijing
Municipal Science and Technology Commission as “high and new technology enterprise” under the EIT Law. In
February 2009, Baidu Online and Baidu Times received the high and new technology enterprise certificates jointly
issued by the Beijing Municipal Science and Technology Commission, Beijing Finance Bureau, and Beijing State
and Local Tax Bureaus. Therefore, Baidu Online and Baidu Times are entitled to enjoy a preferential tax rate of 15%
as long as they maintain their qualification as “high and new technology enterprise”. If either or both of them fail to
maintain the “high and new technology enterprise” qualification, their applicable EIT rate may increase to up to
25%, which could have a material adverse effect on our results of operations. We cannot assure you that we will be
able to maintain our current effective tax rate in the future.

In 2006, our PRC subsidiary Baidu China was designated as a “software enterprise” by the Shanghai Municipal
Information Commission and was entitled to a full exemption from the EIT from 2006 to 2007 and a 50% reduced
rate from 2008 to 2010 based on then-effective tax laws and regulations. With the promulgation of the EIT Law, all
preferential EIT treatments granted prior to January 1, 2008, other than those treatments specified under the EIT
Law and related regulations, were repealed. Accordingly, the preferential tax treatment granted to Baidu China as a
“software enterprise” was no longer effective as of January 1, 2008. However, we have been informed by the
Shanghai Pudong State Tax Bureau that Baidu China may continue to enjoy a 50% reduced EIT rate, or a rate of
12.5%, from 2008 to 2010 as a “software enterprise.” If such preferential tax treatment granted by local tax
authorities is repealed by higher state authorities, Baidu China’s effective EIT rate for 2008 to 2010 may be
increased, which could adversely affect our results of operations.

In addition, under the EIT Law and related regulations, dividends, interests, rent or royalties payable by a
foreign-invested enterprise, such as our PRC subsidiaries, to any of its foreign non-resident enterprise investors, and
proceeds from the disposition of assets (after deducting the net value of such assets) by such foreign enterprise
investor, shall be subject to a 10% withholding tax unless such foreign enterprise investor’s jurisdiction of
incorporation has a tax treaty with China that provides for a reduced rate of withholding tax. Undistributed profits
earned by foreign-invested enterprises prior to January 1, 2008 are exempted from any withholding tax. The British
Virgin Islands, where the direct parent company of our PRC subsidiary Baidu Online is incorporated, does not have
such a tax treaty with China. Baidu (Hong Kong) Limited, or Baidu Hong Kong, which directly owns our PRC
subsidiaries Baidu China and Baidu Times, was incorporated in Hong Kong. Hong Kong has a tax treaty with China
that provides for a 5% withholding tax.

Our PRC subsidiaries historically have not paid dividends to us. If they declare and distribute dividends in the
future, such dividend payments will be subject to withholding tax, which will increase our tax liability and reduce
the amount of cash available to our company.

We may be deemed a PRC resident enterprise under the EIT Law, which could subject us to PRC
taxation on our global income, and which may have a material adverse effect on our results of
operations.

Under the EIT Law and related regulations, an enterprise established outside of the PRC with “de facto
management bodies” within the PRC is considered a PRC resident enterprise and is subject to the EIT at the rate of
25% on its worldwide income. The related regulations define the term “de facto management bodies” as
“establishments that carry out substantial and overall management and control over the manufacturing and
business operations, personnel, accounting, properties, etc. of an enterprise.” If we are deemed a PRC resident
enterprise, we may be subject to the EIT at 25% on our global income, except that the dividends we receive from our
PRC subsidiaries may be exempt from the EIT to the extent such dividends are deemed as “dividends among
qualified PRC resident enterprises.” If we are considered a resident enterprise and earn income other than dividends
from our PRC subsidiaries, a 25% EIT on our global income could significantly increase our tax burden and
materially and adversely affect our cash flow and profitability.

Under the EIT Law, dividends payable by us and gains on the disposition of our shares or ADSs may be
subject to PRC taxation.

If we were considered a PRC resident enterprise under the EIT Law, our shareholders and ADS holders who are
deemed non-resident enterprises may be subject to the EIT at the rate of 10% upon the dividends payable by us or
upon any gains realized from the transfer of our shares or ADSs, if such income is deemed derived from China,
provided that (i) such foreign enterprise investor has no establishment or premises in China, or (ii) it has
establishment or premises in China but its income derived from China has no real connection with such
establishment or premises. If we were required under the EIT Law to withhold PRC income tax on our dividends
payable to our non-PRC enterprise shareholders and ADS holders, or if any gains realized from the transfer of our
shares or ADSs by our non-PRC enterprise shareholders and ADS holders were subject to the EIT, your investment
in our shares or ADSs would be materially and adversely affected.

Our subsidiaries and affiliated entities in China are subject to restrictions on paying dividends and
making other payments to us.

We are a holding company incorporated in the Cayman Islands and do not have any assets or conduct any
business operations other than our investments in our subsidiaries and affiliated entities. As a result of our holding
company structure, we currently rely entirely on dividend payments from our subsidiaries in China. However, PRC
regulations currently permit payment of dividends only out of accumulated profits, as determined in accordance
with PRC accounting standards and regulations. Our subsidiaries and consolidated affiliated entities in China are
also required to set aside a portion of their after-tax profits according to PRC accounting standards and regulations
to fund certain reserve funds. The PRC government also imposes controls on the conversion of RMB into foreign
currencies and the remittance of currencies out of China. We may experience difficulties in completing the
administrative procedures necessary to obtain and remit foreign currency. See “— Government control of currency
conversion may affect the value of your investment.” Furthermore, if our subsidiaries or consolidated affiliated
entities in China incur debt on their own in the future, the instruments governing the debt may restrict their ability to
pay dividends or make other payments. If we or any of our subsidiaries in China are unable to receive all of the
revenues from our operations through these contractual or dividend arrangements, we may be unable to pay
dividends on our ordinary shares and ADSs.

Uncertainties with respect to the PRC legal system could adversely affect us.

We conduct our business primarily through our subsidiaries and affiliated entities in China. Our operations in
China are governed by PRC laws and regulations. Our subsidiaries are generally subject to laws and regulations
applicable to foreign investments in China and, in particular, laws applicable to wholly foreign owned enterprises.

The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited
precedential value.

PRC legislation and regulations have significantly enhanced the protections afforded to various forms of
foreign investments in China for the past three decades. However, China has not developed a fully integrated legal
system and recently-enacted laws and regulations may not sufficiently cover all aspects of economic activities in
China. In particular, because these laws and regulations are relatively new, and because of the limited volume of
published decisions and their nonbinding nature, the interpretation and enforcement of these laws and regulations
involve uncertainties. Furthermore, the PRC legal system is based in part on government policies and internal rules
(some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may
not be aware of our violation of these policies and rules until some time after the violation. In addition, any litigation
in China may be protracted and result in substantial costs and diversion of resources and management attention.

Governmental control of currency conversion may affect the value of your investment.

The PRC government imposes controls on the convertibility of RMB into foreign currencies and, in certain
cases, the remittance of currency out of China. We receive substantially all of our revenues in RMB. Under our
current structure, our income is primarily derived from dividend payments from our PRC subsidiaries. Shortages in
the availability of foreign currency may restrict the ability of our PRC subsidiaries and affiliated entities to remit
sufficient foreign currency to pay dividends or other payments to us, or otherwise satisfy their foreign currency
denominated obligations. Under existing PRC foreign exchange regulations, payments of current account items,
including profit distributions, interest payments and expenditures from trade-related transactions, can be made in
foreign currencies without prior approval from the PRC State Administration of Foreign Exchange, or SAFE, by
complying with certain procedural requirements. However, approval from appropriate government authorities is
required where RMB is to be converted into foreign currency and remitted out of China to pay capital expenses such
as the repayment of bank loans denominated in foreign currencies. The PRC government may also at its discretion
restrict access in the future to foreign currencies for current account transactions. If the foreign exchange control
system prevents us from obtaining sufficient foreign currency to satisfy our currency demands, we may not be able
to pay dividends in foreign currencies to our shareholders, including holders of our ADSs.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents
and registration requirements for employee stock ownership plans or share option plans may subject our
PRC resident beneficial owners or the plan participants to personal liability, limit our ability to inject
capital into our PRC subsidiaries, limit our subsidiaries’ ability to increase their registered capital or
distribute profits to us, or may otherwise adversely affect us.

SAFE has promulgated several regulations, including SAFE Circular No. 75, effective from November 2005,
and its implementation rule issued in May 2007, that require PRC residents and PRC corporate entities to register
with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special
purpose vehicles, or SPV, for the purposes of overseas equity financing activities. These regulations apply to our
shareholders who are PRC residents and may apply to any offshore acquisitions that we make in the future.

Under these SAFE regulations, PRC residents who make, or have previously made, direct or indirect
investments in an SPV are required to register those investments. In addition, any PRC resident who is a direct
or indirect shareholder of an SPV is required to update the previously filed registration with the local branch of
SAFE, with respect to that SPV, to reflect any material change involving its round-trip investment, capital variation,
such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt
investment or creation of any security interest. Moreover, the PRC subsidiaries of that SPV are required to urge the
PRC resident shareholders to update their SAFE registration with the local branch of SAFE when such updates are
required under applicable SAFE regulations. If any PRC shareholder fails to make the required SAFE registration or
file or update the registration, the PRC subsidiaries of that SPV may be prohibited from distributing their profits and
the proceeds from any reduction in capital, share transfer or liquidation, to their SPV, and the SPV may also be
prohibited from injecting additional capital into their PRC subsidiaries. Moreover, failure to comply with the
various SAFE registration requirements described above could result in liability under PRC laws for evasion of
applicable foreign exchange restrictions.

We have notified holders of ordinary shares of our company whom we know are PRC residents to register with
the local SAFE branch and update their registrations as required under the SAFE regulations described above. We
are aware that our major shareholders who are PRC residents have registered with the relevant local SAFE branch.
We, however, cannot provide any assurances that all of our shareholders who are PRC residents will make or obtain
any applicable registrations or approvals required by these SAFE regulations. The failure or inability of our PRC
resident shareholders to comply with the registration procedures set forth therein may subject such PRC resident
shareholders to fines and legal sanctions, restrict our cross-border investment activities, or limit our PRC
subsidiaries’ ability to distribute dividends or obtain foreign exchange-dominated loans to our company.

As it is uncertain how the SAFE regulations described above will be interpreted or implemented, we cannot
predict how these regulations will affect our business operations or future strategy. For example, we may be subject
to more stringent review and approval process with respect to our foreign exchange activities, such as remittance of
dividends and foreign currency-denominated borrowings, which may adversely affect our results of operations and
financial condition. In addition, if we decide to acquire a PRC domestic company, we cannot assure you that we or
the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the
necessary filings and registrations required by the SAFE regulations. This may restrict our ability to implement our
acquisition strategy and could adversely affect our business and prospects.

In December 2006, the People’s Bank of China promulgated the Administrative Measures of Foreign
Exchange Matters for Individuals, setting forth the respective requirements for foreign exchange transactions
by PRC individuals under either the current account or the capital account. In January 2007, SAFE issued
implementing rules for the Administrative Measures of Foreign Exchange Matters for Individuals, which, among
other things, specified approval requirements for certain capital account transactions such as a PRC citizen’s
participation in the employee stock ownership plans or stock option plans of an overseas publicly listed company.
On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for
Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed
Company, or the Stock Option Rule. Under the Stock Option Rule, PRC citizens who are granted stock options by
an overseas publicly listed company are required, through a PRC agent or PRC subsidiary of such overseas publicly-
listed company, to register with SAFE and complete certain other procedures. We and our PRC employees who have
been granted stock options are subject to these regulations. We have designated our PRC subsidiary Baidu Online to
handle the registration and other procedures required by the Stock Option Rule. If we or our PRC optionees fail to
comply with these regulations in the future, we or our PRC optionees and their local employers may be subject to
fines and legal sanctions.

A regulation adopted in August 2006 establishes more complex procedures for acquisitions conducted by
foreign investors, which could make it more difficult for us to pursue growth through acquisitions.

On August 8, 2006, six PRC regulatory agencies, namely, the PRC Ministry of Commerce, or the MOC, the
State Assets Supervision and Administration Commission, the State Administration for Taxation, the SAIC, the
China Securities Regulatory Commission and SAFE, jointly adopted the Regulations on Mergers and Acquisitions
of Domestic Enterprises by Foreign Investors, which became effective on September 8, 2006. Among other things,
the new regulations established additional procedures and requirements that could make merger and acquisition
activities by foreign investors more time-consuming and complex, including requirements in some instances that
the MOC be notified in advance of any change-of-control transaction in which a foreign investor takes control of a
PRC domestic enterprise. We may grow our business in part by directly acquiring complementary businesses in
China. Complying with the requirements of the new regulations to complete such transactions could be time-
consuming, and any required approval processes, including obtaining approval from the MOC, may delay or inhibit
our ability to complete such transactions, which could affect our ability to expand our business or maintain our
market share.

Fluctuation in the value of the RMB may have a material adverse effect on your investment.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among
other things, changes in political and economic conditions. On July 21, 2005, the PRC government changed its
decade-old policy of pegging the value of the RMB to the U.S. dollar. Under the current policy, the RMB is

29

BOM  H03242  030.00.00.00  8

permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change
in policy has resulted in an approximately 17.4% appreciation of the RMB against the U.S. dollar between July 21,
2005 and April 3, 2009. On May 19, 2007, the People’s Bank of China announced a policy to expand the maximum
daily floating range of the RMB trading prices against the U.S. dollar in the inter-bank spot foreign exchange market
from 0.3% to 0.5%. With this increased floating range, the RMB’s value may appreciate or depreciate significantly
against the U.S. dollar in the long term. However, under the current global financial and economic conditions, we
are not able to predict with any certainty how the RMB will move vis-à-vis the U.S. dollar in the future.

Our revenues and costs are mostly denominated in RMB, while a significant portion of our financial assets are
denominated in U.S. dollars. We currently rely entirely on dividends and other fees paid to us by our subsidiaries
and consolidated affiliated entities in China. Any significant revaluation of RMB may materially and adversely
affect our cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, our
ADSs in U.S. dollars. For example, an appreciation of RMB against the U.S. dollar would make any new RMB
denominated investments or expenditures more costly to us, to the extent that we need to convert U.S. dollars into
RMB for such purposes. An appreciation of RMB against the U.S. dollar would also result in foreign currency
translation losses for financial reporting purposes when we translate our U.S. dollar denominated financial assets
into RMB, as RMB is our reporting currency. Conversely, a significant depreciation of the RMB against the
U.S. dollar may significantly reduce the U.S. dollar equivalent of our earnings, which in turn could adversely affect
the price of our ADSs.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of avian influenza, SARS or another epidemic or
outbreak. In recent years, there have been reports on the occurrences of avian influenza in various parts of China,
including a few confirmed human cases. Any prolonged recurrence of avian influenza, SARS or other adverse
public health developments in China may have a material adverse effect on our business operations. For instance,
health or other government regulations adopted in response to an epidemic or outbreak may require temporary
closure of Internet cafes, which is where many users access our websites, or of our offices. Such closures would
severely disrupt our business operations and adversely affect our results of operations. We have not adopted any
written preventive measures or contingency plans to combat any future outbreak of avian influenza, SARS or any
other epidemic.

We may incur substantial administrative and staffing cost due to the promulgation of the new labor
contract law.

On June 29, 2007, the Standing Committee of the National People’s Congress of China enacted the Labor
Contract Law, which became effective on January 1, 2008. The Labor Contract Law contains substantial provisions
with a view to improve job security and to protect the rights and interests of employees. In order to fully comply
with the legal requirements under the Labor Contract Law, we may incur substantial administrative and staffing
cost.

Risks Related to Our ADSs

The trading price of our ADSs has been volatile and may continue to be volatile regardless of our
operating performance.

The trading price of our ADSs has been and may continue to be subject to wide fluctuations. During the period
from August 5, 2005, the first day on which our ADSs were listed on the Nasdaq, until April 8, 2009, the trading
prices of our ADSs ranged from $44.44 to $429.19 per ADS and the closing sale price on April 8, 2009 was $182.59
per ADS. The market price for our ADSs may continue to be volatile and subject to wide fluctuations in response to
factors including the following:

(cid:129) actual or anticipated fluctuations in our quarterly operating results;

(cid:129) changes in financial estimates by securities research analysts;

(cid:129) conditions in Internet search and online marketing markets;

30

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:15 NO MARKS 

NEXT PCN: 032.00.00.00 -- Page is valid, no graphics

BOM  H03242  031.00.00.00  8

(cid:129) changes in the economic performance or market valuations of other Internet search or Internet companies

that are perceived to be comparable to us;

(cid:129) announcements by us or our competitors of new products, acquisitions, strategic partnerships, joint ventures

or capital commitments;

(cid:129) addition or departure of key personnel;

(cid:129) fluctuations of exchange rates between RMB and the U.S. dollar;

(cid:129) intellectual property litigation; and

(cid:129) general economic or political conditions in China or elsewhere in the world.

In addition, the stock market in general, and the market prices for Internet-related companies and companies
with operation in China in particular, have experienced volatility that often has been unrelated to the operating
performance of such companies. In particular, the global financial crisis and the ensuing deteriorating global
economic conditions have contributed and may continue to contribute to extreme volatility in the global stock
markets. These broad market and industry fluctuations may adversely affect the price of our ADSs, regardless of our
operating performance. Volatility or a lack of positive performance in our stock price may also adversely affect our
ability to retain key employees, most of whom have been granted options or other equity incentives.

Substantial future sales or the perception of sales of our ADSs in the public market could cause the price
of our ADSs to decline.

Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market
price of our ADSs to decline. Such sales also might make it more difficult for us to sell equity or equity-related
securities in the future at a time and price that we deem appropriate. If any existing shareholder or shareholders sell a
substantial amount of ADSs, the prevailing market price for our ADSs could be adversely affected.

In addition, we may issue additional ordinary shares for future acquisitions. If we pay for our future
acquisitions in whole or in part with additionally issued ordinary shares, your ownership interests in our company
would be diluted and this, in turn, could have a material adverse effect on the price of our ADSs.

You may not have the same voting rights as the holders of our ordinary shares and may not receive voting
materials in time to be able to exercise your right to vote.

Except as described in this annual report and in the deposit agreement, holders of our ADSs will not be able to
exercise voting rights attaching to the shares evidenced by our ADSs on an individual basis. Holders of our ADSs
will appoint the depositary or its nominee as their representative to exercise the voting rights attaching to the shares
represented by the ADSs. You may not receive voting materials in time to instruct the depositary to vote, and it is
possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the
opportunity to exercise a right to vote. Upon our written request, the depositary will mail to you a shareholder
meeting notice which contains, among other things, a statement as to the manner in which your voting instructions
may be given, including an express indication that such instructions may be given or deemed given to the depositary
to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from you
on or before the response date established by the depositary. However, no voting instruction shall be deemed given
and no such discretionary proxy shall be given with respect to any matter as to which we inform the depositary that
(i) we do not wish such proxy given, (ii) substantial opposition exists, or (iii) such matter materially and adversely
affects the rights of shareholders.

You may not be able to participate in rights offerings and may experience dilution of your holdings as a
result.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities.
Under the deposit agreement for the ADSs, the depositary will not offer those rights to ADS holders unless both the
rights and the underlying securities to be distributed to ADS holders are either registered under the Securities Act, or
exempt from registration under the Securities Act with respect to all holders of ADSs. We are under no obligation to

31

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:15 NO MARKS 

NEXT PCN: 033.00.00.00 -- Page is valid, no graphics

BOM  H03242  032.00.00.00  8

file a registration statement with respect to any such rights or underlying securities or to endeavor to cause such a
registration statement to be declared effective. In addition, we may not be able to take advantage of any exemptions
from registration under the Securities Act. Accordingly, holders of our ADSs may be unable to participate in our
rights offerings and may experience dilution in their holdings as a result.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer
books at any time or from time to time when it deems expedient in connection with the performance of its duties. In
addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the
books of the depositary are closed, or at any time if we or the depositary deems it advisable to do so because of any
requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or
for any other reason.

You may face difficulties in protecting your interests, and your ability to protect your rights through the
U.S. federal courts may be limited, because we are incorporated under Cayman Islands law, conduct most
of our operations in China and all of our officers reside outside the United States.

We are incorporated in the Cayman Islands, and conduct most of our operations in China through our wholly-
owned subsidiaries in China. All of our officers reside outside the United States and some or all of the assets of those
persons are located outside of the United States. As a result, it may not be possible to effect service of process within
the United States or elsewhere outside China upon our senior executive officers, including with respect to matters
arising under U.S. federal securities laws or applicable state securities laws.

It may also be difficult or impossible for you to bring an action against us or against these individuals in the
Cayman Islands or in China in the event that you believe that your rights have been infringed under the securities
laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and
of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.
There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the
courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of
competent jurisdiction without retrial on the merits. Moreover, our PRC counsel has advised us that the PRC does
not have treaties with the United States or many other countries providing for the reciprocal recognition and
enforcement of judgment of courts.

Our corporate affairs are governed by our memorandum and articles of association and by the Companies Law
(2007 Revision) and common law of the Cayman Islands. The rights of shareholders to take legal action against our
directors and us, actions by minority shareholders and the fiduciary responsibilities of our directors to us under
Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of
the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well
as from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands.
The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as
clearly established as they would be under statutes or judicial precedents in the United States. In particular, the
Cayman Islands has a less developed body of securities laws as compared to the United States, and provides
significantly less protection to investors. In addition, Cayman Islands companies may not have standing to initiate a
shareholder derivative action before the federal courts of the United States.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests
through actions against our management, directors or major shareholders than would shareholders of a corporation
incorporated in a jurisdiction in the United States.

Our dual-class ordinary share structure with different voting rights could discourage others from
pursuing any change of control transactions that holders of our Class A ordinary shares and ADSs may
view as beneficial.

Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A
ordinary shares are entitled to one vote per share, while holders of Class B ordinary shares are entitled to 10 votes

32

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:15 NO MARKS 

NEXT PCN: 034.00.00.00 -- Page is valid, no graphics

BOM  H03242  033.00.00.00  8

per share. We issued Class A ordinary shares represented by our ADSs in our initial public offering. Certain of our
major shareholders, including our co-founder, chairman and chief executive officer, Robin Yanhong Li, who
acquired our shares prior to our initial public offering, hold our Class B ordinary shares. Each Class B ordinary share
is convertible into one Class A ordinary share at any time by the holder thereof. Class A ordinary shares are not
convertible into Class B ordinary shares under any circumstances. Upon any transfer of Class B ordinary shares by a
holder thereof to any person or entity which is not an affiliate of such holder, such Class B ordinary shares shall be
automatically and immediately converted into the equal number of Class A ordinary shares. In addition, if at any
time Robin Yanhong Li and his affiliates collectively own less than 5% of the total number of the issued and
outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share shall be automatically and
immediately converted into one share of Class A ordinary share, and we shall not issue any Class B ordinary shares
thereafter.

Due to the disparate voting powers attached to these two classes, certain shareholders have significant voting
power over matters requiring shareholder approval, including election of directors and significant corporate
transactions, such as a merger or sale of our company or our assets. This concentrated control could discourage
others from pursuing any potential merger, takeover or other change of control transactions that holders of Class A
ordinary shares and ADSs may view as beneficial.

Our articles of association contain anti-takeover provisions that could adversely affect the rights of
holders of our ordinary shares and ADSs.

Our articles of association include certain provisions that could limit the ability of others to acquire control of
our company, and deprive our shareholders of the opportunity to sell their shares at a premium over the prevailing
market price by discouraging third parties from seeking to obtain control of our company in a tender offer or similar
transactions, including the following provisions:

(cid:129) A dual-class ordinary share structure.

(cid:129) Our board of directors has the authority, without approval by the shareholders, to issue up to a total of
10,000,000 preferred shares in one or more series. Our board of directors may establish the number of shares
to be included in each such series and may fix the designations, preferences, powers and other rights of the
shares of a series of preferred shares.

(cid:129) Our board of directors has the right to elect directors to fill a vacancy created by the increase of the board of
directors or the resignation, death or removal of a director, which prevents shareholders from having the sole
right to fill vacancies on our board of directors.

We may be classified as a passive foreign investment company, which could result in adverse U.S. federal
income tax consequence to U.S. Holders.

Based on the price of the ADSs and our ordinary shares, the composition of our income and assets and our
operations, we believe that we were not a “passive foreign investment company,” or PFIC, for United States federal
income tax purposes for our taxable year ended December 31, 2008. However, we must make a separate
determination each year as to whether we are a PFIC (after the close of each taxable year) and we cannot assure
you that we will not be a PFIC for our current taxable year ending December 31, 2009 or any taxable year. A
non-U.S. corporation will be considered a PFIC for any taxable year if either (1) at least 75% of its gross income is
passive income or (2) at least 50% of the value of its assets (based on an average of the quarterly values of the assets
during a taxable year) is attributable to assets that produce or are held for the production of passive income. The
future value of our assets is generally determined by reference to the market price of our ADSs and ordinary shares,
which may fluctuate considerably. If we were treated as a PFIC for any taxable year during which a U.S. Holder held
an ADS or an ordinary share, certain adverse U.S. federal income tax consequences could apply to the U.S. Holder.

Investment Company.”

INFORMATION ON THE COMPANY

A. History and Development of the Company

We were incorporated in the Cayman Islands in January 2000. Since our inception, we have conducted our
operations in China principally through Baidu Online, our wholly-owned subsidiary in Beijing, China. We also have
conducted part of our operations in China through Baidu Netcom, a consolidated affiliated entity in Beijing, China,
which holds the licenses and approvals necessary to operate our websites and provide online advertising services. In
addition, we have established three PRC subsidiaries and assisted in establishing two PRC consolidated affiliated
entities in recent years. We formally launched a Japanese search service in January 2008 and now have three
subsidiaries in Japan.

On August 5, 2005, we listed our ADSs on The Nasdaq National Market (later renamed The Nasdaq Global
Market) under the symbol “BIDU.” We and certain selling shareholders of our company completed the initial public
offering of 4,604,224 ADSs, each representing one Class A ordinary share, on August 10, 2005. Our ADSs currently
trade on The Nasdaq Global Select Market, a segment of The Nasdaq Global Market.

In December 2008, our shareholders approved our name change from Baidu.com, Inc. to Baidu, Inc.

Our principal executive offices are located at 12/F, Ideal International Plaza, No. 58 West-North 4th Ring,

Beijing 100080, People’s Republic of China. Our telephone number at this address is +86 (10) 8262-1188.

B. Business Overview

We are the leading Chinese language Internet search provider. As a technology-based media company, we aim
to provide the best way for people to find information. In addition to serving Internet search users, we provide an
effective platform for businesses to reach potential customers. According to a market survey announced by
iResearch Consulting Group, a third-party market research firm, our search engine Baidu.com processed approx-
imately 1.1 trillion Chinese language web search requests in 2008, accounting for 73.2% of the total Chinese
language web search market in China. According to Alexa.com, our Baidu.com website was the largest website in
China, as measured by user traffic during the three-month period ended December 31, 2008.

We serve three types of online participants:

Users. We primarily offer a Chinese language search platform on our website www.baidu.com. We provide
Chinese language Internet search services to enable users to find relevant information online, including web pages,
news, images and multimedia files, through links provided on our websites. We also offer online community-based
products and entertainment platforms such as Baidu Post Bar, Baidu Knows and Baidu Space. In addition, we
currently offer beta versions of Baidu Hi, our IM service and Baidu Youa, our C2C service.

Customers. We design and deliver our online marketing services on our website www.baidu.com to our P4P
customers and other customers who require our tailored online marketing solutions. Our auction-based P4P services
enable our customers to bid for priority placement of their links in keyword search results. We believe we were the
first auction-based P4P service provider in China. Our online advertising services allow customers to use both query
sensitive and non-query sensitive advertising services, including text links, graphical advertisements and other
forms of online advertising. Our P4P customers are those who primarily use our auction-based P4P services, and our
tailored solutions customers are those to whom we provide marketing solutions, which may consist of one or more
forms of our online advertising services as well as P4P services. In the fourth quarter of 2008, we had over 197,000
active online marketing customers.

Baidu Union Members. Baidu Union includes a large number of third-party web content and software
providers. Baidu Union members typically incorporate a Baidu search box into their websites. We provide high-
quality and relevant search to their users, and in return gain the benefit of increased traffic. We have also launched
programs through which we display online advertisements of our customers on Baidu Union members’ websites
and share the fees generated by these advertisements with the owners of these Baidu Union websites.

We established our Japanese subsidiary Baidu Japan in December 2006 and offered a trial version of our
Japanese search services beginning in March 2007. In January 2008, we formally launched our Japanese search

Online Marketing Services

P4P. Our P4P platform enables our customers to reach users who search for information related to their
products or services. Customers may use our automated online tools to create text-based descriptions of their web
pages and bid on keywords that trigger the display of their web page information and link. Our P4P platform
features an automated online sign-up process that allows customers to activate their accounts at any time.

Our P4P platform is an online marketplace that introduces Internet search users to customers who bid for
priority placement in the search results. We engage third-party distributors to sell some of our online marketing
services to end customers and offer discounts to distributors as consideration for their services. Prior to September
2006, links to customers’ websites were listed in descending order of customers’ bids, with the highest bidder
appearing as the first search result. In September 2006, we implemented an intelligent ranking system, which takes
into consideration the “quality factor” of a keyword in addition to the price bid on the keyword. The quality factor of
a keyword is determined based on the relevance of a keyword and certain other factors. The relevance of a keyword
is determined based on our analysis of past search and click-through results. Links to customers’ websites now are
ranked according to a comprehensive ranking index, calculated based on both the quality factor of a keyword and
the price bid on that keyword.

Our P4P online marketing customers may choose to set a daily limit on the amount spent and may also choose
to target only users accessing our website from specified regions in China. In addition, they can see the competing
bids on the same keywords. This transparent bidding process creates competition among customers.

We offer certain customers value-added consultative services that help to maximize their return on investment,

or ROIs, including:

(cid:129) Keyword Suggestions — We suggest synonyms and associated phrases to use as keywords or text in search
listings. These suggestions can improve click-through rates of the customer’s listing and increase the
likelihood that a user will enter into a transaction with the customer;

(cid:129) Account Management — We help manage customers’ P4P accounts by, among other things, adjusting
keywords from time to time at their request to help increase the click-through rate for their listings; and

(cid:129) Performance Reporting — We provide our customers online daily reports of the number of click-throughs,
clicked keywords and the total costs incurred, as well as statistical reports organized by geographic region.

In November 2008, we announced Phoenix Nest, a new online marketing system currently in beta testing
phase. Phoenix Nest is designed to improve relevance in paid search and increase value for customers, thus driving
monetization efficiency. Phoenix Nest will achieve these objectives through an enhanced algorithm that generates
more relevant advertisements and provides customers with additional tools and information that can help them
better manage their spending to achieve higher ROI.

ProTheme. We offer ProTheme services to some of our Baidu Union members. Our services enable these
Baidu Union members to display on their properties our customers’ promotional links that are relevant to the subject
and content of such members’ properties. We generate revenues from our ProTheme services based on the number
of clicks on our customers’ links and share the revenues with our Baidu Union members in accordance with pre-
agreed terms.

Fixed Ranking. Our fixed ranking services allow our customers to display query sensitive text links at a
designated location on our search results pages. Our customers pay us an amount based primarily on the location of
their text links on our web pages.

Targetizement. Our Targetizement services enable our customers to reach their targeted Internet users by
displaying their advertisements only when their targeted Internet users browse Baidu’s certain web pages. The
customers pay us a fee based on the number of clicks on their advertisements.

Baidu TV. We operate our advertising service, Baidu TV, in partnership with Ads it! Media Corporation, an
online advertising agency and technology company. Baidu TV provides advertisers access to the websites of our
Baidu Union members, allowing advertisers to choose websites on which they post their video advertisements with
the aid of our advertisement targeting and matching system. The customers pay us a fee based on the number of

effective views on their advertisements. An effective view is counted when a video advertisement runs at least five
seconds before a viewer closes it.

Brand-Link. We offer a brand advertising service, Brand-Link. When Internet users conduct a key word
search using brand names of our customers who subscribe to our Brand-Link services, the search will generate a
wide range of brand-specific content, including news reports, promotional announcements, product information
and marketing campaigns. The customers pay us a fee based on the duration of the placement of the brand-specific
content.

My Marketing Center.

In June 2008, we launched “My Marketing Center”, a customized platform integrating
industry information, market trends and business and industry news and reports to assist existing customers in their
sales and marketing efforts. The platform combines our vast resources in online information search and aggregation
to help customers make better use of search marketing tools to improve customer targeting, increase sales and
enhance brand impact.

Other Forms of Online Advertising. Other forms of our online advertising services allow customers to
display query sensitive and non-query sensitive advertisements on our websites, including graphical advertise-
ments. Our advertising contracts are generally short-term. Standard rates for online advertisements vary depending
on several factors, including the term of the contract, channel and traffic reach and the size and position of the
advertisement on our web pages.

Other Services

Prior to July 2006, our other services primarily included enterprise search software and related services to
companies and government agencies in China. We developed, marketed and sold software that employed our search
technology to search and manage information on our customers’ intranet and on the Internet. In July 2006, we
decided to phase out the enterprise search software business as part of a strategic shift to focus on our core online
marketing services. This phase-out was completed in March 2008.

We provided our search engine to selected Chinese Internet portals that offered search results to their own users
without displaying our brand during the early stage of our development. We discontinued our portal search services
in 2006.

Baidu Union

Our Baidu Union consists of a large number of third-party websites and software applications. Our Baidu
Union members typically incorporate a Baidu search box or toolbar and match our sponsored links with the content
on their properties. Their users can conduct search via the Baidu search box or toolbar and can click the sponsored
links located on their properties. Our relationships with Baidu Union members allow them to provide high-quality
and relevant search results to their users without the costs associated with building and maintaining advanced search
capabilities in-house. Moreover, our Baidu Union members can monetize their traffic and content through revenue
sharing arrangement with us, which is based on the number of click-throughs from their users. We have also
launched programs through which we display the online advertising of our customers on Baidu Union websites and
share the fees generated by these advertisements with the owners of these Baidu Union websites. We intend to
recruit additional Baidu Union members to further increase traffic to our Baidu.com website.

Our Customers

Online Marketing. We serve a broad range of online marketing customers consisting of SMEs throughout
China, large domestic corporations and Chinese divisions or subsidiaries of large, multinational corporations. We
have a diverse customer base in terms of industries and geographical locations. The industries in which our
customers operate include e-commerce, information technology services, consumer products, electronic products,
machinery, manufacturing, medical, entertainment, education, franchising, financial services, real estate, ticketing,
tourism and other industries. Although we have customers located throughout China, we have a more active and
larger customer base in coastal regions, reflecting the current general economic demographics in China.

Our online marketing customers are increasingly seeking marketing solutions with measurable results in order
to maximize their ROI. In response to this trend, we manage our sales activities for our online marketing services
around two key customer categories: P4P customers and tailored solutions customers.

(cid:129) P4P Customers — Our P4P customers are those who primarily use our auction-based P4P services. They are
generally SMEs with modest marketing budgets and, as a result, require cost-effective online marketing
solutions to reach their potential customers. Our P4P platform allows them, directly or through our
distributors, to easily manage their online marketing spending on a prepaid basis.

(cid:129) Tailored Solutions Customers — Our tailored solutions customers generally seek solutions to meet certain
pre-determined performance metrics, such as number of click-throughs, duration of placement, number of
converted users and number of telephone calls. They are generally medium and large enterprises with
dedicated online marketing budgets. Depending on their objectives and desired end results, we design
customized performance-based solutions comprising of P4P, fixed ranking and other query and non-query
sensitive marketing services.

Sales and Distribution

We sell our online marketing services directly and through our distribution network. We have historically
acquired our P4P customers primarily through our nationwide network of distributors and, to a lesser extent,
through our direct sales force. In early 2005, we started to establish direct sales offices in a number of major cities in
China. Currently we have direct sales presence in Shanghai, Beijing and major cities in Guangdong Province,
including Shenzhen, Guangzhou, and Dongguan.

Our distributors provide numerous services, including identifying customers, collecting payments, assisting
customers in setting up accounts with us, suggesting keywords to maximize ROI and engaging in other marketing
and educational services aimed at acquiring customers. We have relied on distributors for several reasons. Our P4P
customer base in China is geographically diverse and fragmented as most of our P4P customers are SMEs located in
different regions in China. Moreover, SMEs are generally less experienced with online marketing as compared to
large companies and therefore benefit from the extensive services provided by distributors. Finally, secure online
payment and credit card systems are at early stages of development in China. Distributors serve as an efficient and
effective channel to reach SME customers throughout China and collect payments from them.

We offer our tailored marketing solutions to medium and large corporate customers primarily through our
direct sales force. We have local sales staff in Beijing, Shanghai and major cities in Guangdong Province, including
Shenzhen, Guangzhou, and Dongguan, covering the largest regional markets for our online advertising services.

Marketing

Historically, our user base grew primarily through word-of-mouth. We focus on continuously improving the
quality of our products and services as we believe satisfied users and customers are more likely to recommend our
products and services to others. Through these efforts and the increased use of the Internet in China, we have built
our brand with modest marketing expenditures.

Our initial public offering in 2005 has significantly enhanced our brand recognition. In addition, we have
implemented a number of marketing initiatives designed to promote our brand awareness among potential users and
customers. For example, we purchased advertisements shown during CCTV’s 2009 Spring Festival Gala, the most
watched show on China’s largest nationwide television network. We have also conducted cross-marketing activities
with a number of leading consumer brands.

In addition, with the assistance from our distributors, we conduct localized marketing activities tailored to
potential customers in various regions. We also organize and sponsor seminars and discussion forums targeted at
existing and potential customers.

Strategic Relationships

In 2008, we entered into several strategic relationships to further expand our user base and cooperate with more

leading global companies.

In February 2008, we entered into a cooperation agreement with China Netcom (Group) Company Limited.
Pursuant to this agreement, users of China Netcom’s Internet connection services will be directed to a search page
featuring a Baidu search box after they input an incorrect or nonexistent Internet address. We also entered into a
cooperation agreement with Omniture Inc., a leading provider of online business optimization software. Under this
agreement, we will integrate our technology with Omniture to allow Omniture’s clients direct access to the Chinese
online market.

In March 2008, we entered into a cooperation agreement with Qingdao Haier to jointly promote online media
television services. Under this agreement, we will provide Internet services and technology support to Haier’s
online television scheme, which enables Chinese television users to access Baidu’s services with a remote control.

In April 2008, we entered into a cooperation agreement with Nokia to strengthen our existing collaboration
with Nokia. Under this agreement, users of certain Nokia mobile phone models will be able to access Baidu search
services via Widsets, Nokia’s wireless Internet platform.

In July 2008, we entered into a cooperation agreement with Waseda University, a Japanese university
specializing in science and technology. Under this agreement, Baidu and Waseda jointly established a research and
development program to explore and develop Japanese language search technology.

In November 2008, we entered into a cooperation agreement with Willcom Inc., a leading Japanese mobile
phone provider and operator. Under this agreement, travelers in Japan will be able to access Chinese-language voice
search services through Willcom’s personal handy-phone system.

Competition

The Internet search industry in China is rapidly evolving and highly competitive. Our primary competitors
include U.S.-based Internet search providers providing Chinese language Internet search services and Chinese
Internet companies. We compete with these entities for both users and customers on the basis of user traffic, quality
(relevance) and quantity (index size) of search results, availability and ease of use of our products and services, the
number of customers, distribution channels and the number of associated third-party websites. We also face
competition from traditional advertising media. Furthermore, our new IM and C2C services face competition from
leading providers of these services in China.

U.S.-based Internet Search Providers. U.S.-based Internet search providers such as Google and Yahoo! have
a strong global presence, well-established brand names, more users and customers and significantly greater
financial resources than we do. Google’s Chinese website google.cn is our major competitor in Chinese language
search. We may face more intense competition from our U.S.-based competitors as the regulatory environment in
China evolves, online payment systems and Internet infrastructure in China mature, and our U.S.-based competitors
increase their business activities in China.

Chinese Internet Companies. Chinese Internet portals such as Sina, Sohu, Netease and Tencent offer a broad
range of online services, including news, wireless value-added services, email, online shopping, blogs, chat rooms
and community networks. Sina has its own search engine, “iAsk,” and Sohu also has its own search engine, Sogou.
Each of our Chinese Internet portal competitors has generated significant traffic, a loyal user base and a large and
broad customer base. These portals have widely recognized brand names in China and some have greater financial
resources than we do. We compete with these portals primarily for user traffic and online advertising. In addition,
we compete with B2B service providers such as Alibaba.

Other Advertising Media. Other advertising media, such as newspapers, yellow pages, magazines, billboards
and other forms of outdoor media, television and radio, compete for a share of our customers’ marketing budgets.
Large enterprises currently spend a relatively small percentage of their marketing budgets on online marketing as
compared to the percentage they spend on other advertising media.

IM and C2C Service Providers. Baidu Hi, our new IM service, competes primarily with Tencent’s QQ and
MSN Messenger. Baidu Youa, our new C2C platform, faces competition primarily from C2C service providers such
as Alibaba’s Taobao, Tencent’s Paipai and EachNet, a joint venture of eBay and Tom Online.

Technology

We provide our web search and P4P technology using our network of computers running customized software

developed in-house. Our key technologies include:

Web Search Technology

Our web search technology applies a combination of techniques to determine the importance of a web page

independent of a particular search query and the relevance of that page to a particular search query.

Link Analysis Techniques. Link analysis is a technique that determines the relevance between a user query
and a web page by evaluating the combination of the anchor texts and the number of web pages linked to that web
page. We treat a link from web page A to web page B as a “vote” by page A in favor of page B. The subject of the
“vote” is described in the anchor texts of that link. The more “votes” a web page gets, the higher the relevance. We
compare search queries with the content of web pages to help determine relevance. Our text-based scoring
techniques do more than count the number of times a search term appears on a web page. For example, our
technology determines the proximity of individual search terms to each other on a given web page, and prioritizes
results that have the search terms near each other. Other aspects of a page’s content are also considered. By
combining link analysis with our information extraction techniques, we are able to deliver relevant search results.

Information Extraction Techniques. We extract information from a web page using high performance
algorithms and information extraction techniques. Our techniques enable us to understand web page content, delete
extraneous data, build link structures, identify duplicate and junk pages and decide whether to include or exclude a
web page based on its quality. Our techniques can process millions of web pages quickly. In addition, our anti-
spamming algorithms and tools can identify and respond to spamming web pages quickly and effectively.

Web Crawling Techniques. Our powerful computer clusters and intelligent scheduling algorithms allow us to
crawl Chinese web pages efficiently. We can easily scale up our system to collect billions of Chinese web pages. Our
spider technology enables us to refresh web indices at intervals ranging from every few minutes to every few weeks.
We set the index refresh frequency rate based on our knowledge of Internet search users’ needs and the nature of the
information. For example, our news index is typically updated every three to six minutes throughout the day given
the importance of timely information for news. We also mine multimedia and other forms of files from web page
repositories.

In December 2008, we announced Project Aladdin, an ongoing research and development effort aimed at
uncovering useful parts of the “Hidden Web,” the part of the Internet that existing search engine technology may not
be able to index, in order to enrich search results for our users.

Chinese Language Processing Techniques. We analyze and understand Chinese web pages by processing
word-segmentation and utilizing an encoding method based on Chinese language characteristics. For example, we
can identify Chinese names on a web page. When a user searches for a person based on the person’s Chinese name,
we can display the web pages that are specifically related to that person. We also mine user behavior and search
interests from our large search query logs. We provide additional web search features such as advanced search, spell
check and search by Chinese phonetics (Pinyin).

P4P Technology

Our P4P platform serves millions of relevant, targeted sponsored links each day based on search terms users

enter or content they view on the web page. Our key P4P technology includes:

P4P Auction System. We use a web-based auction system to enable customers to bid for positions and
automatically deliver relevant, targeted promotional links on Baidu’s properties and Baidu Union members’
properties. The system starts by screening the relevance between the sponsored links and a particular query. Our

43

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:23 NO MARKS 

NEXT PCN: 045.00.00.00 -- Page is valid, no graphics

BOM  H03242  044.00.00.00  9

intelligent ranking system takes into consideration the quality factor of a keyword in addition to the price bid on the
keyword. The quality factor of a keyword is determined based on the relevance of the keyword and certain other
factors. The relevance of a keyword is determined based on the analysis of past search and click-through results.
Links to customers’ websites are ranked according to a comprehensive ranking index, calculated based on both the
quality factor of a keyword and the price bid or that keyword. We employ a dynamic mechanism for the
determination of the minimum bidding price for each keyword. For determination of cost per click, or CPC, the
system allows customers to set fixed CPCs or choose an automatic price reducing mechanism which automatically
lowers the CPC to the minimum needed to maintain the desired position.

In November 2008, we announced the development of Phoenix Nest, a new keyword auction system. Unlike
our current auction system, Phoenix Nest will be a sealed auction system, which provides customers with more
keyword choices to bid on, more tools for budget management and more data for the effective measurement of ROI.
We also expect the new system to improve Baidu’s monetization efficiency. We are currently testing Phoenix Nest
with select customers on an invitation-only basis.

P4P Billing System. We record every click and charge customers a fee by multiplying the number of clicks
by the CPC. Our system is designed to detect fraudulent clicks based on factors such as click patterns and
timestamps. This system also computes the amount a Baidu Union member or a distributor should be paid. The
billing information is integrated with our internal Oracle ERP financial system.

P4P Customer Service System. This system manages customer information such as targeted keywords, costs

per click and performance analysis.

ProTheme Contextual Promotion Technology. Our ProTheme technology employs techniques that consider
factors such as theme finding, keyword analysis, word frequency and the overall link structure of the web to analyze
the content of individual web pages and to match sponsored links in our P4P platform to the web pages almost
instantaneously. With this targeting technology, we can automatically provide contextually relevant promotional
links. For example, our technology can provide links offering tickets to fans of a specific sports team or a news story
about that team.

Branded Advertising Technology

Targetizement Technology. Our Targetizement technology matches our customers’ advertisements with their
targeted Internet users. Our automatic algorithm can analyze a user’s interests based on his or her past search
experience and display advertisements that the user may be interested in viewing.

Large-Scale Systems Technology

We currently use a combination of off-the-shelf and custom software running on clusters of low-cost
computers. Our investment in our large-scale system infrastructure has several key benefits: simplification of
the storage and processing of large amounts of data, facilitation of the deployment and operation of large-scale
products and services, and automation of much of the administration of large-scale clusters of computers.
Moreover, this large infrastructure is easily scalable to increases in traffic and dataset volume.

Our large-scale system infrastructure uses distributed software and high performance parallel computing
technologies to provide high-quality web search services and web page collection with low cost computer clusters
on a Linux operating system. We also have management information systems that enable us to perform tasks such as
service operations, administration, trouble-shootings and filtering with relative ease and efficiency. In addition, we
have software systems that can test new ideas with real search queries to evaluate the actual effects without affecting
live services.

Our infrastructure significantly improves the relevance of our search and advertising results by allowing us to
apply superior search and retrieval algorithms that are computationally intensive. We believe this infrastructure also
shortens our product development cycle and allows us to innovate more cost-effectively. We also constantly
evaluate new hardware alternatives and software techniques to help further reduce our computational costs.

Intellectual Property

We rely on a combination of trademark, copyright and trade secret protection laws in China and other
jurisdictions, as well as confidentiality procedures and contractual provisions to protect our intellectual property
and our brand. We have six issued patents in China and intend to apply for more patents to protect our core
technologies. We also enter into confidentiality, non-compete and invention assignment agreements with our

intellectual property rights in China and abroad is uncertain and evolving and could involve substantial risks to us.
See “Item 3D. Key Information — Risk Factors — Risks Related to Our Business — We may face intellectual
property infringement claims and other related claims that could be time-consuming and costly to defend and may
result in our inability to continue providing certain of our existing services” and “— We may be subject to patent
infringement claims with respect to our P4P platform.”

Regulation

The PRC government extensively regulates the telecommunications industry, including the Internet sector.
The State Council, the MIIT and other relevant government authorities have promulgated an extensive regulatory
scheme governing Internet-related services. This section summarizes the principal PRC laws and regulations
relating to our business.

In the opinion of Haiwen & Partners, our PRC legal counsel: (1) the ownership structure of our company, Baidu
Online, Baidu China, Baidu Times, Baidu Netcom, Beijing Perusal and BaiduPay complies with current PRC laws
and regulations; (2) subject to the risks disclosed under “Item 3D. Key Information — Risk Factors — Risks
Related to Our Corporate Structure— In order to comply with PRC laws and regulations limiting foreign ownership
of Internet and online advertising businesses, we conduct our ICP and online advertising businesses through our
consolidated affiliated entities in China by means of contractual arrangements. If the PRC government determines
that these contractual arrangements do not comply with applicable regulations, our business could be adversely
affected.” and “— PRC laws and regulations governing our businesses and the validity of certain of our contractual
arrangements are uncertain. If we are found to be in violation, we could be subject to sanctions. In addition, changes
in such PRC laws and regulations or changes in interpretations thereof may materially and adversely affect our
business.”, our contractual arrangements with Baidu Netcom, Beijing Perusal, BaiduPay and their shareholders are
valid and binding on all parties to these arrangements and do not violate existing PRC laws or regulations; and
(3) subject to the completion of the transfers of certain trademarks from Baidu Online to Baidu Netcom, Beijing
Perusal and BaiduPay, the business operations of our company, Baidu Online, Baidu China, Baidu Times, Baidu
Netcom, Beijing Perusal and BaiduPay comply with current PRC laws and regulations in all material respects.

China’s Internet industry and online advertising market are at an early stage of development. There are
substantial uncertainties regarding the interpretation and application of existing or proposed PRC laws and
regulations. We cannot assure you that the PRC regulatory authorities would find that our corporate structure
and our business operations comply with PRC laws and regulations. If the PRC government finds us to be in
violation of PRC laws and regulations, we may be required to pay fines and penalties, obtain certain licenses or
permits and change, suspend or discontinue our business operations until we comply with applicable PRC laws and
regulations.

Regulations on Value-Added Telecommunications Services and Internet Content Services

In September 2000, the State Council promulgated the Telecommunications Regulations, or the Telecom
Regulations. The Telecom Regulations categorize all telecommunications businesses in the PRC as either basic or
value-added. Internet content services, or ICP services, are classified as value-added telecommunications busi-
nesses. Under the Telecom Regulations, commercial operators of value-added telecommunications services must
first obtain an operating license from the MIIT or its provincial level counterparts.

In September 2000, the State Council issued the Administrative Measures on Internet Information Services, or
the Internet Measures. According to the Internet Measures, commercial ICP service operators must obtain an ICP
license from the relevant government authorities before engaging in any commercial ICP operations within the
PRC. In November 2000, the MIIT promulgated the Internet Electronic Messaging Service Administrative
Measures, or the BBS Measures. BBS services include electronic bulletin boards, electronic forums, message
boards and chat rooms. The BBS Measures require ICP operators to obtain specific approvals before providing BBS
services.

In December 2001, the MIIT promulgated the Administrative Measures for Telecommunications Business
Operating License, or the Telecom License Measures. In March 2009, the MIIT issued a revised Telecom License
Measures, which will take effect on April 10, 2009. The Telecom License Measures set forth the types of licenses
required to operate value-added telecommunications services and the qualifications and procedures for obtaining
such licenses. For example, an ICP operator providing value-added services in multiple provinces is required to
obtain an inter-regional license, whereas an ICP operator providing the same services in one province is required to
obtain a local license.

National security considerations are an important factor in the regulation of Internet content in China. The
National People’s Congress, the PRC’s national legislature, has enacted laws with respect to maintaining the
security of Internet operation and Internet content. According to these laws, as well as the Internet Measures,
violators may be subject to penalties, including criminal sanctions, for Internet content that:

(cid:129) opposes the fundamental principles stated in the PRC constitution;

(cid:129) compromises national security, divulges state secrets, subverts state power or damages national unity;

(cid:129) harms the dignity or interests of the state;

(cid:129) incites ethnic hatred or racial discrimination or damages inter-ethnic unity;

(cid:129) undermines the PRC’s religious policy or propagates heretical teachings or feudal superstitions;

(cid:129) disseminates rumors, disturbs social order or disrupts social stability;

(cid:129) disseminates obscenity or pornography, encourages gambling, violence, murder or fear or incites the

commission of a crime;

(cid:129) insults or slanders a third party or infringes upon the lawful rights and interests of a third party; or

(cid:129) is otherwise prohibited by law or administrative regulations.

ICP operators are required to monitor their websites, including electronic bulletin boards. They may not post or
disseminate any content that falls within these prohibited categories and must remove any such content from their
websites.

The PRC government may shut down the websites of ICP license holders that violate any of the above-

mentioned content restrictions and revoke their ICP licenses.

Restrictions on Foreign Ownership in Value-Added Telecommunications Services

According to the Provisions on Administration of Foreign Invested Telecommunications Enterprises, or the
FITE Provisions, promulgated by the State Council in December 2001 and amended in September 2008, the
ultimate foreign equity ownership in a value-added telecommunications services provider must not exceed 50%.
Moreover, for a foreign investor to acquire any equity interest in a value-added telecommunication business in

46

NEXT PCN: 048.00.00.00 -- Page is valid, no graphics

China, it must satisfy a number of stringent performance and operational experience requirements, including
demonstrating good track records and experience in operating value- added telecommunication business overseas.
Foreign investors that meet these requirements must obtain approvals from the MIIT and the MOC (or MOC’s
authorized local counterparts), which retain considerable discretion in granting approvals. According to publicly
available information, the PRC government has issued telecommunications business operating licenses to only a
limited number of foreign invested companies, all of which are Sino-foreign joint ventures engaging in the value-
added telecommunication business. We believe that it would be impracticable for us to acquire any equity interest in
Baidu Netcom, Beijing Perusal or BaiduPay without diverting management attention and resources. In addition, we
believe that our contractual arrangements with Baidu Netcom, Beijing Perusal, BaiduPay and their individual
shareholders provide us with sufficient and effective control over Baidu Netcom, Beijing Perusal and BaiduPay.
Accordingly, we currently do not plan to acquire any equity interest in Baidu Netcom, Beijing Perusal or BaiduPay.

In July 2006, the MIIT issued the Notice of the MIIT on Intensifying the Administration of Foreign Investment
in Value-added Telecommunications Services, or the July 2006 Notice. The July 2006 Notice prohibits domestic
telecommunication services providers from leasing, transferring or selling telecommunications business operating
licenses to any foreign investor in any form, or providing any resources, sites or facilities to any foreign investor for
their illegal operation of a telecommunications business in China. According to the July 2006 Notice, either the
holder of a value-added telecommunication business operating license or its shareholders must directly own the
domain names and trademarks used by such license holders in their provision of value-added telecommunication
services. The July 2006 Notice further requires each license holder to have the necessary facilities, including
servers, for its approved business operations and to maintain such facilities in the regions covered by its license. In
addition, all value-added telecommunication service providers are required to maintain network and Internet
security in accordance with the standards set forth in relevant PRC regulations. If a license holder fails to comply
with the requirements in the July 2006 Notice and cure such non-compliance, the MIIT or its local counterparts have
the discretion to take measures against such license holders, including revoking their valued-added telecommu-
nication business operating licenses.

To comply with these PRC regulations, we operate our websites through Baidu Netcom and Beijing Perusal,
our PRC affiliated entities. In February 2008, we assisted in establishing another consolidated affiliated entity,
BaiduPay, which operate an online payment platform. Baidu Netcom is wholly owned by our chairman, chief
executive officer and co-founder Robin Yanhong Li and our co-founder Eric Yong Xu, both of whom are PRC
citizens. Beijing Perusal is wholly owned by two PRC citizens designated by our company. BaiduPay is wholly
owned by Baidu Netcom and a PRC citizen designated by our company. Each of Baidu Netcom and Beijing Perusal
holds a value-added telecommunications business operating license. It remains unclear whether the provision of
online payment services by BaiduPay will require BaiduPay to apply for a value-added telecommunications
business operating license for “online data processing and transaction processing businesses” as provided in the
Catalog of Telecommunications Businesses promulgated by the MIIT.

To comply with the July 2006 Notice, we have transferred certain domain names primarily used in our business
to Baidu Netcom and Beijing Perusal, respectively. We are also in the process of transferring certain trademarks,
including pending trademark applications made by Baidu Online, to Baidu Netcom, Beijing Perusal and BaiduPay,
respectively. See “Item 3D. Key Information — Risk Factors — Risks Related to Our Corporate Structure — We
may be adversely affected by complexity, uncertainties and changes in PRC regulation of Internet business and
companies, including limitations on our ability to own key assets such as our websites.”

Regulations on News Display

Displaying news on a website and disseminating news through the Internet are highly regulated in the PRC. In
November 2000, the State Council News Office and the MIIT promulgated the Provisional Measures for
Administrating Internet Websites Carrying on the News Displaying Business. These measures require an ICP
operator (other than a government authorized news unit) to obtain State Council News Office approval to post news
on its website or disseminate news through the Internet. Furthermore, the disseminated news must come from
government-approved sources pursuant to contracts between the ICP operator and these sources, copies of which
must be filed with the relevant government authorities.

On September 25, 2005, the State Council News Office and the MIIT jointly issued the Provisions on the
Administration of Internet News Information Services, requiring Internet news information service organizations to
provide services as approved by the State Council News Office, subject to annual inspection under the new
provisions. These Provisions also provide that no Internet news information service organizations may take the
form of a foreign invested enterprise, whether a joint venture or a wholly foreign owned enterprise and no
cooperation between Internet news information service organizations and foreign invested enterprise is allowed
prior to the security evaluation by the State Council News Office.

In December 2006, Baidu Netcom obtained the Internet news license, which permits it to publish Internet news
pursuant to the relevant PRC laws and regulations. The Internet news license is subject to annual inspection by
relevant government authorities.

Regulation on Internet Culture Activities

On May 10, 2003, the Ministry of Culture promulgated the Internet Culture Administration Tentative
Measures, or the Internet Culture Measures, which was revised in July 2004. The Internet Culture Measures
require ICP operators engaging in “Internet culture activities” to obtain a permit from the Ministry of Culture. The
term “Internet culture activities” includes, among other things, online dissemination of Internet cultural products
(such as audio-video products, gaming products, performances of plays or programs, works of art and cartoons) and
the production, reproduction, importation, sale (wholesale or retail), leasing and broadcasting of Internet cultural
products. We have hosted certain audio/video programs on the Baidu Movie channel since 2006. Baidu Netcom was
granted an Internet culture business permit in April 2007.

On November 20, 2006, the Ministry of Culture issued Several Suggestions of the Ministry of Culture on the
Development and Administration of the Internet Music, or the Suggestions, which became effective on
November 20, 2006. The Suggestions, among other things, reiterate the requirement for the Internet service
provider to obtain the Internet culture business permit to carry on any business of Internet music products. In
addition, foreign investors are prohibited from engaging in the Internet culture business operation.

Regulation on Broadcasting Audio/Video Programs through the Internet

On July 6, 2004, the State Administration of Radio Film and Television, or the SARFT, promulgated the Rules
for the Administration of Broadcasting of Audio/Video Programs through the Internet and Other Information
Networks, or the A/V Broadcasting Rules. The A/V Broadcasting Rules apply to the opening, broadcasting,
integration, transmission or download of audio/video programs via the Internet and other information networks.
Anyone who wishes to engage in Internet broadcasting activities must first obtain an audio/video program
transmission license, with a term of two years, issued by the SARFT and operate pursuant to the scope as provided
in such license. Foreign invested enterprises are not allowed to engage in the above business.

On April 13, 2005, the State Council announced Several Decisions on Investment by Non-state-owned
Companies in Culture-related Business in China. These decisions encourage and support non-state-owned com-
panies to enter certain culture-related business in China, subject to restrictions and prohibitions for investment in
audio/video broadcasting, website news and certain other businesses by non-state-owned companies. These
decisions authorize the Ministry of Culture, the SARFT and the General Administration of Press and Publication
to adopt detailed implementation rules according to these decisions.

On December 20, 2007, the SARFT and the MIIT jointly issued the Rules for the Administration of Internet
Audio and Video Program Services, commonly known as Document 56, which came into effect as of January 31,
2008. Document 56 reiterates the requirement set forth in the A/V Broadcasting Rules that online audio/video
service providers must obtain a license from the SARFT. Furthermore, Document 56 requires all online audio/video
service providers to be either wholly state-owned or state-controlled. According to relevant official answers to press
questions published on the SARFT’s website dated February 3, 2008, officials from the SARFT and the MIIT
clarified that online audio/video service providers that already had been operating lawfully prior to the issuance of
Document 56 may re-register and continue to operate without becoming state-owned or controlled, provided that
such providers have not engaged in any unlawful activities. This exemption will not be granted to online audio/
video service providers established after Document 56 was issued. We have hosted on the Baidu Internet TV

channel on our website certain audio/video programs since 2006. Baidu Netcom is in the process of applying for an
audio/video program transmission license. We cannot assure you that we will obtain this license in a timely manner,
or at all. See “Item 3D. Key Information — Risk Factors — Risks Related to Our Corporate Structure — We may
be adversely affected by complexity, uncertainties and changes in PRC regulation of Internet business and
companies, including limitations on our ability to own key assets such as our websites.”

Regulations on Advertisements

The PRC government regulates advertising, including online advertising, principally through the SAIC,
although there are no national PRC laws or regulations specifically regulating online advertising business. Under
the Rules for Administration of Foreign Invested Advertising Enterprise, promulgated by the SAIC and the MOC in
March 2004 and amended in October 2008, foreign investors are permitted to own equity interests in PRC
advertising companies. However, foreign investors in wholly foreign-owned and joint venture Chinese advertising
companies are required to have at least three years and two years, respectively, of direct operations in the advertising
industry outside of China. Since we have not been involved in advertising outside of China for the required number
of years, we cannot hold direct equity interests in PRC companies engaged in advertising business. We conduct our
online advertising business through our consolidated affiliated entities in China, Baidu Netcom and Beijing Perusal.

On November 30, 2004, the SAIC issued the Administrative Regulations for Advertising Operation Licenses,
taking effect as of January 1, 2005, granting a general exemption to enterprises (other than radio stations, television
stations, newspapers and magazines, non-corporate entities and other entities specified in laws or administrative
regulations) from the previous requirement to obtain an advertising operation license in addition to a business
license. We conduct our online advertising business through Baidu Netcom and Beijing Perusal, each of which
holds a business license that includes online advertising in its business scope.

Advertisers, advertising operators and advertising distributors are required by PRC advertising laws and
regulations to ensure that the contents of the advertisements they prepare or distribute are true and in full
compliance with applicable laws and regulations. In addition, where a special government review is required for
certain categories of advertisements before publishing, the advertisers, advertising operators and advertising
distributors are obligated to confirm that such review has been performed and that relevant approval has been
obtained. Violation of these regulations may result in penalties, including fines, confiscation of advertising income,
orders to cease dissemination of the advertisements and orders to publish an advertisement correcting the
misleading information. In circumstances involving serious violations, the SAIC or its local branches may force
the violator to terminate its advertising operation or even revoke its business license. Furthermore, advertisers,
advertising operators or advertising distributors may be subject to civil liability if they infringe on the legal rights
and interests of third parties.

Regulation on Software Products

On October 27, 2000, the MIIT issued the Administrative Measures on Software Products, or the Software
Measures, to strengthen the regulation of software products and to encourage the development of the PRC software
industry. On March 1, 2009, the MIIT issued an amended Software Measures, which will become effective on
April 10, 2009. The Software Measures provide a registration and filing system with respect to software products
made in or imported into China. These software products may be registered with the competent local authorities in
charge of software industry administration. Registered software products may enjoy preferential treatment status
granted by relevant software industry regulations. Software products can be registered for five years, and the
registration is renewable upon expiration.

In order to further implement the Computer Software Protection Regulations promulgated by the State Council
on December 20, 2001, the State Copyright Bureau issued the Computer Software Copyright Registration
Procedures on February 20, 2002, which apply to software copyright registration, license contract registration
and transfer contract registration.

Regulations on Intellectual Property Rights

China has adopted legislation governing intellectual property rights, including trademarks, patents and
copyrights. China is a signatory to the main international conventions on intellectual property rights and became
a member of the Agreement on Trade Related Aspects of Intellectual Property Rights upon its accession to the WTO
in December 2001.

Patent. The National People’s Congress adopted the Patent Law in 1984, and amended it in 1992, 2000 and
2008. The purpose of the Patent Law is to protect and encourage invention, foster applications of invention and
promote the development of science and technology. To be patentable, invention or utility models must meet three
conditions: novelty, inventiveness and practical applicability. Patents cannot be granted for scientific discoveries,
rules and methods for intellectual activities, methods used to diagnose or treat diseases, animal and plant breeds,
substances obtained by means of nuclear transformation or a design which has major marking effect on the patterns
or colors of graphic print products or a combination of both patterns and colors. The Patent Office under the State
Council is responsible for receiving, examining and approving patent applications. A patent is valid for a term of
twenty years in the case of an invention and a term of ten years in the case of utility models and designs. A third-
party user must obtain consent or a proper license from the patent owner to use the patent. Otherwise, the use
constitutes an infringement of patent rights.

Copyright. The National People’s Congress adopted the Copyright Law in 1990 and amended it in 2001 to
widen the scope of works and rights that are eligible for copyright protection. The amended Copyright Law extends
copyright protection to Internet activities, products disseminated over the Internet and software products. In
addition, there is a voluntary registration system administered by the China Copyright Protection Center.

To address copyright issues relating to the Internet, the PRC Supreme People’s Court on November 22, 2000
adopted the Interpretations on Some Issues Concerning Applicable Laws for Trial of Disputes over Internet
Copyright, or the Interpretations, which were subsequently amended on December 23, 2003 and November 20,
2006. The Interpretations establish joint liability for ICP operators if they knowingly participate in, assist in or incite
infringing activities or fail to remove infringing content from their websites after receiving notice from the rights
holder. In addition, any act intended to bypass circumvention technologies designed to protect copyrights
constitutes copyright infringement. Upon request, the ICP operators must provide the rights holder with registration
information of the alleged violator, provided that such rights holder has produced relevant identification, copyright
certificate and evidence of infringement. An ICP operator is exempted from any liabilities as long as it removes the
alleged infringing content after receiving the rights holder’s notice accompanied with proper evidence.

To address the problem of copyright infringement related to the content posted or transmitted over the Internet,
the PRC National Copyright Administration and the MIIT jointly promulgated the Measures for Administrative
Protection of Copyright Related to Internet on April 29, 2005. This measure became effective on May 30, 2005.

This measure applies to situations where an ICP operator (i) allows another person to post or store any works,
recordings, audio or video programs on the websites operated by such ICP operator or (ii) provides links to, or
search results for, the works, recordings, audio or video programs posted or transmitted by such person, without
editing, revising or selecting the content of such material. Upon receipt of an infringement notice from a legitimate
copyright holder, an ICP operator must take remedial actions immediately by removing or disabling access to the
infringing content. If an ICP operator knowingly transmits infringing content or fails to take remedial actions after
receipt of a notice of infringement harming public interest, the ICP operator could be subject to administrative
penalties, including: cessation of infringement activities; confiscation by the authorities of all income derived from
the infringement activities; and payment of a fine of up to three times the unlawful income or, in cases where the
amount of unlawful income cannot be determined, a fine of up to RMB100,000. An ICP operator is also required to
retain all infringement notices for a minimum of six months and to record the content, display time and IP addresses
or the domain names related to the infringement for a minimum of 60 days. Failure to comply with this requirement
could result in an administrative warning and a fine of up to RMB30,000.

On May 18, 2006, the State Council promulgated the Protection of the Right of Communication through
Information Network, which became effective on July 1, 2006. Under this regulation, an Internet service provider
may be exempted from liabilities for providing links to infringing or illegal content if it does not know that such

50

content is infringing upon other parties’ rights or is illegal. However, if the legitimate owner of the content notifies
the Internet service provider and requests removal of the links to the infringing content, the Internet service provider
would be deemed to have constructive knowledge upon receipt of such notification but would be exempted from
liabilities if it removes or disconnects the links to the infringing content at the request of the legitimate owner. At the
request of the alleged violator, the Internet service provider should immediately restore links to content previously
disconnected upon receipt of initial non-infringing evidence.

We have adopted measures to mitigate copyright infringement risks. For example, our policy is to remove links
to web pages if we know these web pages contain materials that infringe third-party rights or if we are notified by the
legitimate copyright holder of the infringement with proper evidence.

Trademark. The PRC Trademark Law, adopted in 1982 and revised respectively in 1993 and 2001, protects
registered trademarks. The Trademark Office under the SAIC handles trademark registrations and grants a term of
ten years to registered trademarks. Trademark license agreements must be filed with the Trademark Office for
record. “
” is recognized as a well-known trademark in China by the Trademark Office under the SAIC. In
addition to owning the trademark “
” and the related logo, we have applied for registration of additional
trademarks and logos, including

.

,

In September 2002, the CNNIC issued the Implementing Rules for Domain Name Registration setting forth
detailed rules for registration of domain names. On November 5, 2004, the MIIT promulgated the Measures for
Administration of Domain Names for the Chinese Internet, or Domain Name Measures. The Domain Name
Measures regulate the registration of domain names, such as the first tier domain name “.cn.” In February 2006,
CNNIC issued the Measures on Domain Name Disputes Resolution and its implementing rules, pursuant to which
CNNIC can authorize a domain name dispute resolution institution to decide disputes. We have registered Baidu.cn,
Baidu.com.cn, hao123.com and certain other domain names with CNNIC.

Regulation on Information Security

The National People’s Congress has enacted legislation that prohibits use of the Internet that breaches the
public security, disseminates socially destabilizing content or leaks state secrets. Breach of public security includes
breach of national security and infringement on legal rights and interests of the state, society or citizens. Socially
destabilizing content includes any content that incites defiance or violations of PRC laws or regulations or
subversion of the PRC government or its political system, spreads socially disruptive rumors or involves cult
activities, superstition, obscenities, pornography, gambling or violence. State secrets are defined broadly to include
information concerning PRC national defense, state affairs and other matters as determined by the PRC authorities.

According to other relevant regulations, ICP operators must complete mandatory security filing procedures
and regularly update information security and censorship systems for their websites with local public security
authorities, and must also report any public dissemination of prohibited content.

In addition, the State Secrecy Bureau has issued provisions authorizing the blocking of access to any website it
deems to be leaking state secrets or failing to comply with the relevant legislation regarding the protection of state
secrets during online information distribution. Specifically, Internet companies in China with bulletin boards, chat
rooms or similar services must apply for specific approval prior to operating such services.

On November 23, 2005, the Ministry of Public Security promulgated Provisions on Technological Measures
for Internet Security Protection, or Internet Protection Measures. The Internet Protection Measures require all ICP
operators to keep records of certain information about its users (including user registration information, log-in and
log-out time, IP address, content and time of posts by users) for at least 60 days and submit the above information as
required by laws and regulations.

As Baidu Netcom and Beijing Perusal are ICP operators, they are subject to the regulations relating to
information security. They have taken measures to comply with such regulations. They are registered with the
relevant government authority in accordance with the mandatory registration requirement. Baidu Netcom’s policy is
to remove links to web pages which to its knowledge contain information that would be in violation of PRC laws or
regulations. In addition, we monitor our websites to ensure our compliance with such laws and regulations.

Regulations on Internet Privacy

The PRC Constitution states that PRC law protects the freedom and privacy of communications of citizens and
prohibits infringement of such rights. In recent years, PRC government authorities have enacted legislation on
Internet use to protect personal information from any unauthorized disclosure. The Internet Measures prohibit an
ICP operator from insulting or slandering a third party or infringing upon the lawful rights and interests of a third
party. Pursuant to the BBS Measures, ICP operators that provide electronic messaging services must keep users’
personal information confidential and must not disclose such personal information to any third party without the
users’ consent or unless required by law. The regulations further authorize the relevant telecommunications
authorities to order ICP operators to rectify unauthorized disclosure. ICP operators are subject to legal liability if the
unauthorized disclosure results in damages or losses to users. The PRC government, however, has the power and
authority to order ICP operators to turn over personal information if an Internet user posts any prohibited content or
engages in illegal activities on the Internet.

Regulations on Foreign Exchange

Foreign Currency Exchange

Pursuant to the Foreign Currency Administration Rules promulgated in 1996 and amended in 1997 and 2008
and various regulations issued by SAFE and other relevant PRC government authorities, RMB is freely convertible
to the extent of current account items, such as trade related receipts and payments, interest and dividends. Capital
account items, such as direct equity investments, loans and repatriation of investment, unless expressly exempted by
laws and regulations, still require prior approval from SAFE or its provincial branch for conversion of RMB into a
foreign currency, such as U.S. dollars, and remittance of the foreign currency outside the PRC.

Payments for transactions that take place within the PRC must be made in RMB. Unless otherwise approved or
permitted, PRC companies must repatriate foreign currency payments received from abroad. The foreign exchange
received by PRC companies, including foreign invested enterprises, may be retained in their foreign exchange
accounts without being exchanged into RMB to the extent permitted by relevant laws and regulations.

Dividend Distribution

The principal regulations governing dividend distributions by wholly foreign owned enterprises and Sino-

foreign equity joint ventures include:

(cid:129) Wholly Foreign Owned Enterprise Law (1986), as amended;

(cid:129) Wholly Foreign Owned Enterprise Law Implementing Rules (1990), as amended;

(cid:129) Sino-foreign Equity Joint Venture Enterprise Law (1979), as amended;

(cid:129) Sino-foreign Equity Joint Venture Enterprise Law Implementing Rules (1983), as amended;

(cid:129) PRC Enterprise Income Tax Law (2007); and

(cid:129) Implementation Rules of the PRC Enterprise Income Tax Law (2007).

Under these regulations, wholly foreign owned enterprises and Sino-foreign equity joint ventures in the PRC
may pay dividends only out of their accumulated profits, if any, as determined in accordance with PRC accounting
standards and regulations. Additionally, these foreign-invested enterprises are required to set aside certain amounts
of their accumulated profits each year, if any, to fund certain reserve funds. These reserves are not distributable as
cash dividends.

Foreign Exchange Registration of Offshore Investment by PRC Residents

Pursuant to SAFE’s Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC
Residents to Engage in Financing and Inbound Investment via Overseas Special Purpose Vehicles, or Circular
No. 75, issued on October 21, 2005, and its implementation rules issued in May 2007, (i) a PRC resident, including a
PRC resident natural person or a PRC company, is required to register with the local branch of SAFE before it

52

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:23 NO MARKS 

NEXT PCN: 054.00.00.00 -- Page is valid, no graphics

BOM  H03242  053.00.00.00  11

establishes or controls an overseas SPV, or SPV, for the purpose of overseas equity financing (including convertible
debt financing); (ii) when a PRC resident contributes the assets of or its equity interests in a domestic enterprise into
an SPV, or engages in overseas financing after contributing assets or equity interests into an SPV, such PRC resident
shall register his or her interest in the SPVand the change thereof with the local branch of SAFE; and (iii) when the
SPV undergoes a material event outside of China, such as change in share capital or merger and acquisition, the PRC
resident must, within 30 days from the occurrence of such event, register such change with the local branch of
SAFE. PRC residents who are shareholders of SPVs that were established and which have completed their inbound
investment before November 1, 2005 were required to register with the local SAFE branch before March 31, 2006.

Under Circular No. 75, failure to comply with the registration procedures set forth above may result in
penalties, including restrictions on a PRC subsidiary’s foreign exchange activities and its ability to distribute
dividends to the SPV.

On December 25, 2006, the People’s Bank of China promulgated the “Measures for the Administration of
Individual Foreign Exchange,” and on January 5, 2007 SAFE further promulgated the implementation rules on
those measures. Both became effective on February 1, 2007. According to the implementation rules, if individuals
in the PRC participate in any employee stock ownership plan or stock option plan of an overseas listed company,
those individuals must apply as a group through the company or a domestic agency to SAFE or the appropriate local
branch for approval for any foreign exchange-related transactions concerning that plan.

On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for
Domestic Individuals Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed
Company. Under this rule, PRC citizens who are granted stock options by an overseas publicly listed company are
required, through a PRC agent or PRC subsidiary of such overseas publicly-listed company, to register with SAFE
and complete certain other procedures.

Regulations on Labor

On June 29, 2007, the National People’s Congress of China enacted the Labor Contract Law, which became
effective on January 1, 2008. Compared to the Labor Law, the Labor Contract Law establishes more restrictions and
increases costs for employers, including specific provisions related to fixed-term employment contracts, temporary
employment, probation, consultation with the labor union and employee assembly, employment without a contract,
dismissal of employees, compensation upon termination and overtime work, and collective bargaining. According
to the Labor Contract Law, an employer is obliged to sign labor contract with unlimited term with an employee if the
employer continues to hire the employee after the expiration of two consecutive fixed-term labor contracts. The
employer has to compensate the employee upon the expiration of a fixed-term labor contract, unless the employee
refuses to renew such contract on terms the same as or better than those contained in the expired contract. The
employer also has to indemnify an employee if the employer terminates a labor contract without a cause permitted
by law. In addition, under the Regulations on Paid Annual Leave for Employees, which became effective on
January 1, 2008, employees who have served more than one year for an employer are entitled to a paid vacation
ranging from 5 to 15 days, depending on their length of service. Employees who waive such vacation time at the
request of employers shall be compensated for three times their regular salaries for each waived vacation day.

Regulations in Japan

Although current Japanese law and regulations contain no provisions expressly directed toward legal control of
Internet search services such as those operated by our Japanese subsidiary in Japan, certain existing Japanese law
and regulations may nonetheless affect such services. The application to our Japanese subsidiary of existing
Japanese law and regulations relating to issues such as intellectual property ownership and infringement, obscenity
and other content regulation, user privacy and data protection, defamation, consumer protection and quality of
services in many instances is unclear or unsettled. In all such cases, there is a possibility that providing, editing and

processing by an Internet search service of links to web pages which contain material in violation of applicable
Japanese law could result in civil or criminal legal liability on the part of such Internet search service. In addition to
the foregoing, there is political and social support within Japan for the adoption of legislation expressly directed to
the legal control of harmful information on the Internet. With this support, a law which aims to protect juveniles
from harmful information on the Internet is being introduced, and it is difficult to predict how much impact such a
law will have on the operation of our Internet search services in Japan.

PRC laws and regulations restrict foreign ownership of ICP and advertising businesses. To comply with PRC
laws, Baidu Netcom was formed by Robin Yanhong Li and Eric Yong Xu on June 5, 2001. Baidu Netcom holds the
licenses and permits necessary to operate our websites and provide our online advertising services in China. Our
relationships with Baidu Netcom and its shareholders are governed by a series of contractual arrangements. We are
the primary beneficiary of Baidu Netcom and are able to substantially control Baidu Netcom through these
contractual arrangements.

In June 2006, we assisted in establishing Beijing Perusal, which is directly owned by two individuals
designated by us. We extended an interest-free loan in an aggregate amount of RMB1.0 million to the shareholders
of Beijing Perusal solely in connection with the initial capitalization of Beijing Perusal. We entered into a series of
agreements with Beijing Perusal and its shareholders in order to be the primary beneficiary of, and substantially
control, Beijing Perusal. Beijing Perusal became our consolidated affiliated entity as a result of these contractual
arrangements. Beijing Perusal holds the necessary permits to conduct online advertising services in China.

In February 2008, we assisted in establishing BaiduPay, which is directly owned by Baidu Netcom and an
individual designated by our company. We extended an interest-free loan in an aggregate amount of RMB9.0 million

D. Property, Plant and Equipment

Our principal executive offices are located on premises comprising approximately 29,600 square meters in
Beijing, China. We have branch offices in Shanghai and selected cities in Guangdong Province. We lease our
premises from unrelated third parties. Our servers in China are hosted at the Internet data centers of China Telecom,
China Unicom and China Mobile in Beijing, Tianjin and Shenzhen. In March 2007, we established servers at an
Internet data center of Asia Network Company in Tokyo, Japan.

In late 2005, we made an initial payment for the land use right in Beijing to build our new corporate
headquarters with total floor area of approximately 44,000 square meters. The floor area was increased to
59,000 square meters in 2006. We are building a new information and technology center on the premises and plan to
move our principal executive offices, information and technology center, online marketing services center and
administrative and support facilities to the new premises. We have obtained the necessary governmental approvals
for the proposed development and use of the land, and our new office building is currently under construction.

Item 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion of our financial condition and results of operations is based upon and should be read
in conjunction with our consolidated financial statements and their related notes included in this annual report on
Form 20-F. This report contains forward-looking statements. See “Forward-Looking Information.” In evaluating
our business, you should carefully consider the information provided under the caption “Item 3D. Key Informa-
tion — Risk Factors” in this annual report on Form 20-F. We caution you that our businesses and financial
performance are subject to substantial risks and uncertainties.

A. Operating Results

Overview

Our operations are primarily based in China, where we derive substantially all of our revenues. Total revenues
in 2008 were RMB3.2 billion (US$468.8 million), an 83.3% increase over 2007. Operating profit in 2008 was
RMB1.1 billion (US$160.8 million), a 100.4% increase over 2007. Net income in 2008 was RMB1.0 billion
(US$153.6 million), a 66.6% increase over 2007.

Our total assets as of December 31, 2008 were RMB3.9 billion (US$577.2 million), of which cash and cash
equivalent amounted to RMB2.4 billion (US$346.2 million). Our total liabilities were RMB849.3 million
(US$124.5 million), accounting for 21.6% of total liabilities and shareholders’ equity. As of December 31,
2008, our retained earnings accumulated to RMB2.0 billion (US$290.2 million).

The major factors affecting our results of operations and financial condition are discussed below.

Revenues

Revenue Generation

We derive revenues primarily from online marketing services, which accounted for 98.9%, 99.8% and 99.9%

of our total revenues in 2006, 2007 and 2008, respectively.

We provide online marketing services to our P4P customers and tailored solutions customers. We generated
approximately 99.9% of our total revenues in 2008 from online marketing services, a substantial majority of which
was derived from our P4P services.

Our P4P platform is an online marketplace that introduces Internet search users to customers who bid or pay a
fixed fee based on click-throughs for priority placement of their links in the search results. We recognize P4P
revenues when a user clicks on a customer’s link in the search results, based on the amount that the customer has
agreed to pay for each click-through or, in some cases, other pre-determined performance measures.

We provide tailored solutions customers with marketing solutions which may include one or more forms of
online advertising services such as text links and graphical advertisements, as well as P4P services. Our agreements
with these customers generally have a term of no more than one year. Our tailored solutions customers generally pay
us based on pre-determined performance metrics, such as number of click-throughs, duration of placement, number
of converted users and number of telephone calls. Some of our large tailored solutions customers have increasingly
used our auction-based P4P services as one of the means to meet their online marketing needs. We expect to
continue to experience such trend in the near future.

The most significant factors that directly or indirectly affect our online marketing revenues are:

(cid:129) the number of our users and online marketing customers;

(cid:129) the number of searches initiated on our websites and our Baidu Union members’ properties;

(cid:129) the rate at which users click on paid search results;

(cid:129) the competitiveness of bidding for keywords by P4P customers;

(cid:129) the total online marketing budgets of our customers; and

(cid:129) the total number of sponsored links and advertisements displayed on our websites and the bidding price for

click-through.

Our P4P services revenues have primarily been driven by the increase in the number of page views, the increase
in the number of P4P customers, and by our success in optimizing the display of sponsored links. We believe that an
increase in the number of active P4P customers generally leads to an increase in the number of sponsored links and a
higher average price per click-through for selected keywords. Our P4P customer growth has primarily been driven
by the adoption of our P4P services by SMEs and, to a lesser extent, large enterprises. Our online advertising
services have historically been driven by the general increase in our customers’ online marketing budgets. Most of
our tailored solutions customers are medium and large enterprises. We expect the number of our online marketing
customers to grow and, as a result, our customer mix may change. However, we expect our online marketing
customer base to remain diverse for the foreseeable future. The current economic slowdown in China may cause our
customers to decrease or delay their online marketing spending, hamper our efforts to grow our customer base, or
result in fewer clicks by our users on sponsored links or advertisements displayed on our or Baidu Union members’
websites. Any of these consequences could negatively affect our online marketing revenues.

In November 2008, we removed paid search listings of certain customers, particularly medical and pharma-
ceutical customers without documentations on file with us, in response to CCTV reports that we had been including
websites of medical companies that did not hold proper licenses in our paid search listings for some popular medical
terms. A large portion of those customers have since resumed using our services after providing their relevant
documentations to us. However, the removal of certain questionable sponsored links in November 2008 may result
in a loss of revenues in future periods.

Our online marketing customers are increasingly seeking marketing solutions with measurable results in order
to maximize their ROI. To meet our customers’ needs, we will continue to evaluate the effectiveness of our various
products and services and adjust the mix of our service offerings to optimize our customers’ ROI. We expect that we
will continue to earn a substantial majority of our revenues from our online marketing services. As a result, we plan
to continue focusing most of our resources on expanding our online marketing services.

Prior to July 2006, we had provided enterprise search software and related services. We decided to phase out

our enterprise search software business in July 2006. This phase-out was completed in 2008.

Revenue Collection

We collect payments for our P4P services both from our customers directly and through our distributors. We
have expanded our direct sales effort in several major cities in China, including Beijing, Shanghai, Guangzhou and
Shenzhen and, as a result, an increasing portion of P4P payments is collected through our direct sales. We require
our P4P distributors or direct customers to pay a deposit before using our P4P services, to maintain a minimum
balance in their accounts, and to replenish the accounts immediately or in some cases, within certain grace periods
after their account balance falls below the designated amount. We deduct the amount due to us from the deposit paid
by a distributor or a customer when a user clicks on the customer’s link in the search results.

We offer payment terms to our tailored solutions and online-marketing services customers and longer payment

terms to certain qualified agents, consistent with industry practice.

As of December 31, 2008, we had accounts receivable of RMB92.8 million (US$13.6 million), net of

allowance of RMB8.6 million (US$1.3 million), mainly due from tailored solutions customers.

Operating Costs and Expenses

Our operating costs and expenses consist of cost of revenues, selling, general and administrative expenses, and
research and development expenses. Share-based compensation expenses are allocated among the above three
categories of operating costs and expenses, based on the nature of the work of the employees who have received
share-based compensation. Costs and expenses related to our Japan operations, which started in December 2006, are
included in our cost of revenues, selling, general and administrative expenses and research and development
expenses. Our total operating costs and expenses increased significantly from 2006 to 2008 due to the growth of our
business. However, if we excluded the costs and expenses related to our Japan operations, our total operating costs
and expenses have declined as a percentage of our total revenues from 2006 to 2008 mainly due to economies of
scale and the revenue growth we have achieved.

arrangement, a portion of the online marketing revenues generated from valid click-throughs by users of that
member’s properties.

Bandwidth Costs. Bandwidth costs are the fees we pay to telecommunications carriers such as China
Telecom and China Unicom for telecommunications services and for hosting our servers at their Internet data
centers. We expect our bandwidth costs, as variable costs, to increase with the traffic on our websites. Our
bandwidth costs could also increase if the telecommunications carriers increase their service charges.

Depreciation of Servers and Other Equipment. We include depreciation expenses within our cost of revenues
for servers and other computer hardware that are directly related to our business operations and technical support.

Operational Expenses. Operational expenses include primarily salary and benefits expenses and travel and
other expenses incurred by our operating and technical support personnel. Salary and benefits expenses include
wages, bonuses, and medical insurance, unemployment insurance and pension benefits.

Selling, General and Administrative Expenses

Our selling and marketing expenses primarily consist of salaries and benefits and commissions for our sales
and marketing personnel and promotional and marketing expenses. We expect to incur higher selling and marketing
expenses as we intensify our brand-promotion efforts. To the extent that our direct sales force sells a greater
proportion of our online marketing services, we expect that our selling expense will increase as a result of increased
sales commissions.

Our general and administrative expenses primarily consist of salaries and benefits for our general and

administrative personnel and fees and expenses for legal, accounting and other professional services.

Research and Development Expenses

Research and development expenses primarily consist of salaries and benefits for research and development
personnel. We expense research and development costs as they are incurred, except for capitalized software
development costs that fulfill the capitalization criteria under SOP 98-1, “Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use.”

Share-based Compensation Expenses

We grant options to our employees as a type of share-based compensation award. As of December 31, 2008,
there was RMB43.5 million (US$6.4 million) unrecognized share-based compensation cost related to options. That

58

deferred cost is expected to be recognized over a weighted-average vesting period of 2.04 years. To the extent the
actual forfeiture rate is different from our original estimate, actual share-based compensation cost related to these
awards may be different from our expectation.

In addition to options, we started awarding restricted shares to employees in 2006. As of December 31, 2008,
there was RMB57.6 million (US$8.4 million) unrecognized share-based compensation cost related to restricted
shares. That deferred cost is expected to be recognized over a weighted-average vesting period of 1.32 years. To the
extent the actual forfeiture rate is different from our original estimate, actual share-based compensation cost related
to these awards may be different from our expectation.

We also granted options to consultants and accounted for such options under the fair value method. We
amortize share-based compensation expenses over the vesting periods of the related options, which are generally
four years long.

The following table sets forth the allocation of our share-based compensation expenses both in absolute
amount and as a percentage of total share-based compensation expenses among our employees based on the nature
of work which they were assigned to perform.

Taxation

Under the current laws of the Cayman Islands and the British Virgin Islands, we and Baidu Holdings are not
subject to income or capital gains tax. Under the current laws of Hong Kong, Baidu Hong Kong is exempted from
income tax on its foreign-derived income. Additionally, dividend payments made by any of these companies are not
subject to withholding tax in those jurisdictions.

PRC Enterprise Income Tax

Pursuant to the applicable PRC tax laws and regulations effective before January 1, 2008, foreign-invested
enterprises established in China were generally subject to a state and local enterprise income tax, or EIT, at statutory
rates of 30% and 3%, respectively. An enterprise qualified as a “high and new technology enterprise” and located in
a “national high-tech development zone” was entitled to a preferential EIT rate of 15%. In addition, an enterprise
qualified as a “high and new technology enterprise” located in the Beijing New Technology Industry Development
Zone was entitled to a preferential EIT rate of 15% and would enjoy an exemption from the EIT for the first three
years of its establishment and, upon approval, a 50% reduction of the EIT for the succeeding three years.

In 2006, Baidu Online obtained an “advanced technology enterprise” certificate from the Beijing Municipal
Bureau of Commerce, which qualified Baidu Online for a 10% EIT rate from 2006 to 2007, followed by a 15% tax
rate so long as it continued to qualify as a high and new technology enterprise. Baidu Times, which was a certified
foreign-invested high and new technology enterprise located in Beijing Zhongguancun Science Park (part of the
Beijing New Technology Industry Development Zone), was entitled to a three-year exemption from EIT from 2006
to 2008 and a 7.5% EIT rate for another three years from 2009 to 2011, followed by a 15% tax rate so long as it
continued to qualify as a high and new technology enterprise. Baidu China was granted “software enterprise” status
by the Shanghai Municipal Information Commission in 2006 and thus was entitled to a full exemption from EIT
from 2006 to 2007 and a 50% tax reduction from 2008 to 2010.

On March 16, 2007, the National People’s Congress of China enacted the Enterprise Income Tax Law, or the
EIT Law, which became effective on January 1, 2008. On December 6, 2007, the State Council issued the
Implementation Rules of the Enterprise Income Tax Law, or the Implementation Rules, which also became effective
on January 1, 2008. On December 26, 2007, the State Council issued the Notice on Implementation of Enterprise
Income Tax Transition Preferential Policy under the EIT Law, or the Transition Preferential Policy Circular, which
became effective simultaneously with the EIT Law.

According to the EIT Law, as further clarified by the Implementation Rules and the Transition Preferential
Policy Circular, FIEs and domestic enterprises are subject to EIT at a uniform rate of 25%. The EIT rate of
enterprises established before March 16, 2007 that were eligible for preferential tax rate according to then effective
tax laws and regulations will gradually transition to the uniform 25% EIT rate by January 1, 2013. In addition,
certain enterprises may still benefit from a preferential tax rate of 15% under the EIT Law if they qualify as “high
and new technology enterprises strongly supported by the State,” subject to certain general factors described
therein.

Under the Notice on Several Preferential Policies in Respect of Enterprise Income Tax promulgated jointly by
the Ministry of Finance and the State Administration of Taxation on February 22, 2008, or the Caishui No. 1 Notice,
other than the preferential EIT treatments specified under the EIT Law, the Implementation Rules and certain other
tax regulations, all preferential EIT treatments granted prior to January 1, 2008 are eliminated. Accordingly, the
preferential tax treatments granted to Baidu Online as an “advanced technology enterprise” and to Baidu China as a
“software enterprise” were eliminated as of January 1, 2008. However, we have been informed by the Shanghai
Pudong State Tax Bureau that Baidu China may continue to enjoy a 50% reduced EIT rate, or a rate of 12.5%, from
2008 to 2010 as a “software enterprise.”

On April 14, 2008, the Ministry of Science and Technology, the Ministry of Finance and the State Admin-
istration of Taxation jointly issued the Administrative Measures on the Recognition of High and New Technology
Enterprises, or the Recognition Rules, effective on January 1, 2008. According to the Recognition Rules, the
provincial counterparts of the Ministry of Science and Technology, the Ministry of Finance and the State
Administration of Taxation shall jointly determine whether an enterprise is qualified as a high and new technology
enterprise under the EIT Law. In making such determination, these government agencies shall consider, among
other factors, ownership of core technology, whether the products or services fall within the scope of high and new
technology strongly supported by the state as specified in the Recognition Rules, the ratios of technical personnel
and research and development (R&D) personnel to total personnel, the ratio of R&D expenditures to annual sales
revenues, the ratio of revenues attributed to high and new technology products or services to total revenues, and
other measures set forth in relevant guidance.

In December 2008, our PRC subsidiaries Baidu Online and Baidu Times were designated by relevant
government authorities as “high and new technology enterprise” under the EIT Law. In February 2009, Baidu
Online and Baidu Times received the high and new technology enterprise certificates jointly issued by the Beijing
Municipal Science and Technology Commission, the Beijing Finance Bureau, and the Beijing State and Local Tax
Bureaus. Therefore, Baidu Online and Baidu Times are entitled to enjoy a preferential tax rate of 15% as long as
they maintain their qualification as “high and new technology enterprises” under the EIT Law. In addition, Baidu
Times will continue to benefit from the remaining tax holidays granted to it under the applicable PRC tax laws and
regulations effective before January 1, 2008.

If Baidu Online or Baidu Times fails to maintain the “high and new technology enterprise” qualification under
the EIT Law, or if favorable tax treatment granted to Baidu China by local tax authorities for 2008 to 2010 becomes
unavailable, their tax rates will be increased, which could have a material adverse effect on our results of operations.

Under the EIT Law and the Implementation Rules, dividends, interests, rent or royalties payable by an FIE,
such as our PRC subsidiaries, to any of its foreign non-resident enterprise investors, and proceeds from the
disposition of assets (after deducting the net value of such assets) by such foreign enterprise investor, shall be
subject to a 10% withholding tax unless such foreign enterprise investor’s jurisdiction of incorporation has a tax
treaty with China that provides for a reduced rate of withholding. The Caishui No. 1 Notice issued on February 22,
2008 further clarifies that undistributed profits earned by FIEs prior to January 1, 2008 will be exempted from any
withholding tax. The British Virgin Islands, where our wholly-owned subsidiary Baidu Holdings, which is the sole

shareholder of our PRC subsidiary Baidu Online, is incorporated, does not have such a tax treaty with China. Baidu
Hong Kong, our wholly-owned subsidiary and the sole shareholder of our PRC subsidiaries Baidu China and Baidu
Times, was incorporated in Hong Kong, which has a tax treaty with China that provides for a lower withholding tax
rate of 5%.

Our PRC subsidiaries historically have not paid dividends to us. If they declare and distribute dividends to us in
the future, such dividend payments will be subject to withholding tax, which will increase our tax liability and
reduce the amount of cash available to our company.

Under the EIT Law and the Implementation Rules, an enterprise established outside of the PRC with “de facto
management bodies” within the PRC is considered a resident enterprise and will be subject to the EIT at the rate of
25% on its worldwide income payable to the tax authority where such “de facto management bodies” locate. The
Implementation Rules define the term “de facto management bodies” as “establishments that carry out substantial
and overall management and control over the manufacturing and business operations, personnel, accounting,
properties, etc. of an enterprise.” If we are deemed a resident enterprise, we may be subject to the EIT at 25% on our
global income, except that the dividends we receive from our PRC subsidiary may be exempt from the EIT to the
extent such dividends are deemed “dividends among qualified resident enterprises.” If we are considered a resident
enterprise and earn income other than dividends from our PRC subsidiaries, a 25% EIT on our global income could
significantly increase our tax burden and materially and adversely affect our cash flow and profitability.

The EIT Law and the Implementation Rules have made an effort to scrutinize transactions between related
parties. Pursuant to the EIT Law and the Implementation Rules, the tax authorities may impose mandatory
adjustment on tax due to the extent a related party transaction is not in line with arm’s-length principle or was
entered into with a purpose to reduce, exempt or delay the payment of tax. On January 8, 2009, the State
Administration of Taxation issued the Implementation Measures for Special Tax Adjustments (Trial). The measures
set forth tax-filing disclosure and documentation requirements, clarify the definition of “related party”, guide the
selection and application of transfer pricing methods, and outline the due process procedures for transfer pricing
investigation and assessment.

If Baidu Online, Baidu Times or Baidu China no longer qualifies for the preferential tax treatment, we will
consider available options under applicable law that would enable us to qualify for further preferential tax
treatment. To the extent we are unable to offset the impact of the expiration of Baidu Online’s, Baidu Times’ or
Baidu China’s preferential tax treatment with new tax exemptions, tax incentives or other tax benefits, the
expiration of their preferential tax treatment may cause our effective tax rate to increase. The amount of income tax
payable by our PRC subsidiaries in the future will depend on various factors, including, among other things, the
results of operations and taxable income of, and the statutory tax rate applicable to, each of the subsidiaries. Our
effective tax rate depends partially on the extent of the relative contribution of each of our subsidiaries to our
consolidated taxable income. In 2007 and 2008, our consolidated effective tax rate was -2.1% and 9.97%,
respectively.

If P4P were classified as a form of advertising in the future, we may have to conduct our P4P business through
Baidu Netcom in order to comply with PRC laws and regulations that limit foreign ownership of online advertising
companies. As a result, our consolidated effective tax rate would increase, as Baidu Netcom is subject to a 25%
statutory enterprise income tax rate as of the date of this annual report.

PRC Business Tax

Revenues from our P4P services are subject to a 5% PRC business tax. Revenues from our online advertising
services are subject to business taxes, surcharges and cultural business construction fees totaling approximately
8.5% of the online advertising revenues. Revenues from our other services are also subject to a 5% business tax.

PRC Value-added Tax

Other than providing online marketing services, Baidu Online sold proprietary software before July 2006,
which was subject to PRC value-added tax, or VAT. In July 2006, we decided to phase out the enterprise search

software business. Since the phase-out of this business has been completed, Baidu Online is no longer subject to the
VAT relating to software sales.

Results of Operations

The following table sets forth a summary of our consolidated results of operations for the periods indicated.
Our business has evolved rapidly since we commenced operations in 2000. Our limited operating history makes it
difficult to predict future operating results. We believe that period-to-period comparisons of operating results
should not be relied upon as indicative of future performance.

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Revenues. Our total revenues increased by 83.3% from RMB1.7 billion in 2007 to RMB3.2 billion
(US$468.8 million) in 2008. This increase was primarily due to a substantial increase in our revenues from online
marketing services. Our online marketing revenues increased by 83.5% from RMB1.7 billion in 2007 to
RMB3.2 billion (US$468.2 million) in 2008. This increase was mainly attributable to the increase in the number
of our online marketing customers from approximately 214,000 in 2007 to over 284,000 in 2008, and the increase in
the average revenue per customer from approximately RMB8,100 in 2007 to approximately RMB11,200
(US$1,642) in 2008. The increase in our online marketing customers was mainly due to our effective distribution
network and our expanded direct sales, especially in Beijing, Shanghai, Guangzhou and Shenzhen. The increase in
the average revenue per customer was primarily attributable to the increase in the number of paid clicks, and the

higher price per click as more customers participated in our P4P auction platform. The number of paid clicks
increased by approximately 48% from 2007 to 2008.

Operating Costs and Expenses. Our total operating costs and expenses increased by 75.5% from RMB1.2 billion
in 2007 to RMB2.1 billion (US$308 million) in 2008. This increase was primarily due to the expansion of our business.

(cid:129) Cost of Revenues. Our cost of revenues increased by 79.0% from RMB645.4 million in 2007 to
RMB1.2 billion (US$169.4 million) in 2008. This increase was primarily due to the following factors:

(cid:129) Traffic Acquisition Costs. Our traffic acquisition costs increased by 104.4% from RMB204.7 million in
2007 to RMB418.5 million (US$61.3 million) in 2008. This was primarily due to the growth of revenue
contribution from our Baidu Union members.

(cid:129) Bandwidth Costs and Depreciation Expenses. Our bandwidth costs increased by 52.0% from
RMB117.6 million in 2007 to RMB178.7 million (US$26.2 million) in 2008. Our depreciation expenses
of servers and other computer hardware increased by 53.5% from RMB147.1 million in 2007 to
RMB225.8 million (US$33.1 million) in 2008. The absolute increases in these costs were due to the
expansion of our business. However, these costs in 2008 accounted for a lower percentage of total
revenues than in 2007. The decreases in bandwidth costs and depreciation expenses as percentages of total
revenues reflect our improved efficiency as well as increased scalability of capital expenditures.

(cid:129) Business Tax and Surcharges. Our business tax and surcharges increased by 83.9% from RMB108.8 million
in 2007 to RMB200.1 million (US$29.3 million) in 2008, primarily as a result of increase in our online
marketing revenues.

(cid:129) Operational Expenses. Our operational expenses increased by 95.1% from RMB65.5 million in 2007 to
RMB127.9 million (US$18.7 million) in 2008, primarily due to the increase in the number and
compensation levels of our operating and technical support employees to meet the needs of our growing
operations.

(cid:129) Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased
by 60.5% from RMB411.2 million in 2007 to RMB659.8 million (US$96.7 million) in 2008. This increase
was primarily due to the following factors:

(cid:129) total salaries and benefits and staff-related expenses increased by 61.8% from RMB218.7 million in 2007
to RMB353.8 million (US$51.9 million) in 2008, primarily due to the increased direct sales and
administrative headcount to support our expanded online marketing services;

(cid:129) share-based compensation expenses allocated to selling, general and administrative expenses increased
by 139.8% from RMB17.4 million in 2007 to RMB41.7 million (US$6.1 million) in 2008 primarily due to
share-based awards granted to the new senior management personnel hired in 2008;

(cid:129) total office operating expenses increased by 37.6% from RMB56.1 million in 2007 to RMB77.2 million

(US$11.3 million) in 2008, as a result of increase and expansion of our direct sales offices;

(cid:129) total traveling, communication and entertainment expenses increased by 46.6% from RMB16.3 million in
2007 to RMB23.9 million (US$3.5 million) in 2008, primarily due to the increased administrative and
direct sales headcount and activities to support our expanded online marketing services; and

(cid:129) Research and Development Expenses. Our research and development expenses increased by 103.4% from
RMB140.7 million in 2007 to RMB286.3 million (US$42.0 million) in 2008, primarily due to an increase in
the number and compensation levels of research and development staff.

Operating Profit. As a result of the foregoing, we generated an operating profit of RMB1.1 billion

(US$160.8 million) in 2008, a 100.4% increase from 2007.

Taxation. Our income tax expenses were RMB116.1 million (US$17.0 million) in 2008, compared to an
income tax benefit of RMB12.8 million in 2007. The income tax expenses in 2008 were primarily due to one of our
PRC subsidiaries being subject to an EIT rate of 12.5% in 2008, after the expiration of its full exemption from the

63

ACEBOWNE OF MONTREAL, INC

NEXT PCN: 065.00.00.00 -- Page is valid, no graphics

BOM  H03242  064.00.00.00  8

EIT. Our income tax benefit in 2007 was primarily due to receipt of an incentive tax refund of RMB21.2 million
arising from capital reinvestment in one of our PRC subsidiaries.

Other income, net, including exchange gains or losses. Our other income, net, including exchange gains or

losses was RMB19.8 million (US$2.9 million) in 2008, compared to RMB20.1 million in 2007.

Net Income. As a result of the foregoing, we had net income of RMB1.0 billion (US$153.6 million) in 2008,

a 66.6% increase from RMB629.0 million in 2007.

Year Ended December 31, 2007 Compared to Year Ended December 31, 2006

Revenues. Our total revenues increased by 108.2% from RMB837.8 million in 2006 to RMB1.7 billion in
2007. This increase was primarily due to a substantial increase in our revenues from online marketing services. Our
online marketing revenues increased by 110.1% from RMB828.5 million in 2006 to RMB1.7 billion in 2007. This
increase was mainly attributable to the increase in the number of our online marketing customers from approx-
imately 143,000 in 2006 to over 214,000 in 2007, and the increase in the average revenue per customer from
approximately RMB5,800 in 2006 to approximately RMB8,100 in 2007. The increase in our online marketing
customers was mainly due to our effective distribution network and our expanded direct sales, especially in Beijing,
Shanghai, Guangzhou and Shenzhen. The increase in the average revenue per customer was primarily attributable
to the increase in the number of paid clicks, and the higher price per click as more customers participated in our P4P
auction platform. The number of paid clicks increased by 77.6% from 2006 to 2007.

Operating Costs and Expenses. Our total operating costs and expenses increased by 108.2% from
RMB575.0 million in 2006 to RMB 1.2 billion in 2007. This increase was primarily due to increases in our cost
of revenues, and, to a lesser extent, an increase in our selling, general and administrative expenses as well as
research and development expenses.

(cid:129) Cost of Revenues. Our cost of revenues increased by 162.9% from RMB245.5 million in 2006 to

RMB645.4 million in 2007. This increase was primarily due to the following factors:

(cid:129) Business Tax and Surcharges. Our business tax and surcharges increased by 109.9% from RMB51.8 million
in 2006 to RMB108.8 million in 2007, primarily as a result of increase in our online marketing revenues.

(cid:129) Traffic Acquisition Costs. Our traffic acquisition costs increased by 172.3% from RMB75.2 million in
2006 to RMB204.7 million in 2007. This was primarily due to the growth of revenue contribution from our
Baidu Union members.

(cid:129) Bandwidth Costs. Our bandwidth costs increased by 193.8% from RMB40.0 million in 2006 to
RMB117.6 million in 2007, as a result of increased bandwidth to support increased traffic in our existing
market in China and the new Japan market.

(cid:129) Depreciation Expenses of Servers and Other Equipment. Our depreciation expenses of servers and other
computer hardware increased by 185.3% from RMB51.6 million in 2006 to RMB147.1 million in 2007, as
we acquired more servers, network equipment and computer hardware to meet increased user traffic and
accommodate growing online marketing services.

(cid:129) Operational Expenses. Our operational expenses increased by 157.2% from RMB25.5 million in 2006
to RMB65.5 million in 2007, primarily due to the increase in the number and compensation levels of our
operating and technical support employees to meet the needs of our growing operations.

(cid:129) Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased
by 64.3% from RMB250.2 million in 2006 to RMB411.2 million in 2007. This increase was primarily due to
the following factors:

(cid:129) total salaries and benefits and staff-related expense increased by 96.0% from RMB111.6 million in 2006
to RMB218.7 million in 2007, primarily due to the increased direct sales and administrative headcount to
support our expanded online marketing services;

64

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:23 NO MARKS 

NEXT PCN: 066.00.00.00 -- Page is valid, no graphics

BOM  H03242  065.00.00.00  8

(cid:129) total office operating expenses increased by 69.2% from RMB33.2 million in 2006 to RMB56.1 million in

2007, as a result of increase and expansion of our direct sales offices; and

(cid:129) total traveling, communication and entertainment expenses increased by 58.1% from RMB10.3 million in
2006 to RMB16.3 million in 2007, primarily due to the increased administrative and direct sales
headcount to support our expanded online marketing services.

The above increases were offset by a 47.3% decrease in share-based compensation expenses for staff
performing selling, general and administrative functions from RMB33.0 million in 2006 to RMB17.4 million
in 2007, primarily due to a decrease in the amount of share-based awards granted.

(cid:129) Research and Development Expenses. Our research and development expenses increased by 77.6% from
RMB79.2 million in 2006 to RMB140.7 million in 2007, primarily as a result of the increased headcount and
increased compensation levels.

Operating Profit. As a result of the foregoing, we generated an operating profit of RMB547.2 million in

2007, a 108.1% increase from 2006.

Taxation. Our income tax benefit was RMB12.8 million in 2007, which was primarily due to our receipt of an
incentive tax refund of RMB21.2 million arising from capital reinvestment in one of our PRC subsidiaries in the
fourth quarter of 2007.

Other income, net, including exchange gains or losses. The increase in 2007 was due primarily to our receipt

of RMB14.6 million in government subsidies in 2007.

Cumulative effect of change in accounting principle. The cumulative benefit of RMB4.6 million in 2006 was
due to the adoption of SFAS 123R, which reflects the net cumulative impact of estimating future forfeitures for the
options granted in the third and fourth quarters of 2005. There was no cumulative effect in adopting FIN 48.

Net Income. As a result of the foregoing, we had net income of RMB629.0 million in 2007, a 108.4%

increase compared to net income of RMB301.8 million in 2006.

Inflation

Inflation in China has not materially impacted our results of operations. According to the National Bureau of
Statistics of China, the change of consumer price index in China was 1.6%, 4.8% and 5.9% in 2006, 2007 and 2008,
respectively. Although we were not materially affected by inflation in the past, we can provide no assurance that we
will not be affected in the future by potentially higher rates of inflation in China. For example, certain operating
costs and expenses, such as employee compensation and office operating expenses may increase as a result of higher
inflation. Additionally, because a substantial portion of our assets consists of cash and cash equivalents and short-
term investments, high inflation could significantly reduce the value and purchasing power of these assets. We are
not able to hedge our exposure to higher inflation in China.

Foreign Currency

The average exchange rate between U.S. dollar and RMB has declined from RMB8.2264 per U.S. dollar in
July 2005 to RMB6.8539 per U.S. dollar in December 2008. The functional currency of our subsidiaries in Japan is
the Japanese yen, and their reporting currency is RMB. During 2008, the Japanese yen appreciated by approx-
imately 15% against RMB. As of December 31, 2008, we recorded RMB27.6 million (US$4.0 million) of net
foreign currency translation loss in accumulated other comprehensive loss as a component of shareholders’ equity.
We have not hedged exposures to exchange fluctuations using any hedging instruments. See also “Item 3D. Key
Information — Risk Factors — Risks Related to Doing Business in China — Fluctuation in the value of the RMB
may have a material adverse effect on your investment.” and “Item 11. Quantitative and Qualitative Disclosures
About Market Risk — Foreign Exchange Risk.”

Critical Accounting Policies

We prepare financial statements in accordance with U.S. GAAP, which requires us to make judgments,
estimates and assumptions that affect the reported amounts of our assets and liabilities and the disclosure of our
contingent assets and liabilities at the end of each fiscal period and the reported amounts of revenues and expenses
during each fiscal period. We continually evaluate these judgments and estimates based on our own historical
experience, knowledge and assessment of current business and other conditions, our expectations regarding the
future based on available information and assumptions that we believe to be reasonable, which together form our
basis for making judgments about matters that are not readily apparent from other sources. Since the use of
estimates is an integral component of the financial reporting process, our actual results could differ from those
estimates. Some of our accounting policies require a higher degree of judgment than others in their application.

The selection of critical accounting policies, the judgments and other uncertainties affecting application of
those policies and the sensitivity of reported results to changes in conditions and assumptions are factors that should
be considered when reviewing our financial statements. For further information on our significant accounting
policies, see Note 2 to our consolidated financial statements. We believe the following accounting policies involve
the most significant judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

We recognize revenues based on the following principles:

Online Marketing Services

(1) Auction-based P4P Services

Our auction-based P4P platform enables a customer to place its website link and related description on our
search result list. The customers make bids to determine how much they are willing to pay for each click to their
listings in the search results listed on our website. The amount of the customer’s bid will influence the ranking of the
customer’s listing in the search results. The customer pays us only when a user clicks on one of its website links.
Revenue is recognized when a user clicks on one of the customer-sponsored website links, there is persuasive
evidence of an arrangement, the fee is fixed or determinable and collection is reasonably assured, as prescribed by
SEC Staff Accounting Bulletin No. 104, or SAB 104.

For certain P4P customers engaged through direct sales, we may provide certain value-added consultative
services to help our customers better utilize its P4P online marketing system. Fees for such services are recognized
as revenue on a pro-rata basis over the contracted service period.

(2) Other Performance-based Online Marketing Services

To the extent we provide online marketing services based on performance criteria other than click-throughs,
such as the number of telephone calls brought to our customers, the number of users registered with our customers,
or the minimum number of click-throughs, revenue is recognized when the specified performance criteria are met
together with satisfaction of other applicable revenue recognition criteria as prescribed by SAB 104.

(3) Time-based Online Advertising Services

For time-based online advertising services such as text links, banners or other forms of graphical advertise-
ments, we recognize revenue, in accordance with SAB 104, on a pro-rata basis over the contractual term
commencing on the date the customer’s advertisement is displayed in a specified webpage. For certain time-
based contractual agreements, we may also provide certain performance guarantees, in which cases revenue is
recognized at the later of the completion of the time commitment or performance guarantee.

(4) Online Marketing Services Involving Baidu Union

Baidu Union is the program through which we expand distribution of our customers’ sponsored links or
advertisements by leveraging traffic of the Baidu Union members’ Internet properties. We make payments to Baidu

Union members for acquisition of traffic. We recognize gross revenue for the amount of fees we receive from our
customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs.

(5) Barter Transactions

We may engage in barter transactions from time to time and in such situations follow the provisions of
Accounting Principles Board No. 29, Accounting for Nonmonetary Transactions. While nonmonetary transactions
are generally recorded at fair value, if such value is not determinable within reasonable limits, we recognize the
transaction based on the carrying value of the product or services we provide. The amount of revenues recognized
for barter transactions was insignificant for each of the periods presented.

In addition, we recognized revenues for barter transactions involving advertising in accordance with Emerging
Issues Task Force, or EITF 99-17, Accounting for Advertising Barter Transactions. However, neither the amount
recognized nor the volume of such transactions not qualified for income recognition was material for any of the
periods presented.

According to EITF 00-8, Accounting by a Grantee for an Equity Instrument to Be Received in Conjunction
with Providing Goods or Services, if we provide services in exchange for equity instruments, we are required to
measure the fair value of those equity instruments for revenue recognition purposes as of the earlier of either of the
following dates:

(cid:129) The date the parties come to a mutual understanding of the terms of the equity-based compensation

arrangement and a commitment for performance by us to earn the equity instruments is reached; or

(cid:129) The date at which our performance necessary to earn the equity instruments is completed.

If as of the measurement date, the fair value of the equity instruments received is not determinable within
reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of
both the equity instruments received and the services provided cannot be determined, no revenue is to be recognized
for the services provided and the equity instrument received is to be recorded at zero carrying value. The amount of
revenues recognized for such transactions was not material for any of the years presented.

(6) Other Revenue Recognition Related Policies

If a sales contract stipulates more than one of the services described in (1), (2) and (3), and the services are
considered as multiple accounting units in accordance with EITF 00-21, Revenue Arrangements with Multiple
Deliverables, the total revenue on such arrangements is allocated to the individual deliverables based on their
relative fair values. If sufficient vendor-specific objective evidence of fair value does not exist for the allocation of
revenue, the fee for the entire arrangement is recognized ratably over the term of the arrangement.

We engage third party distributors to deliver some of our online marketing services to end customers. In this
context, we may provide cash incentives to distributors. The cash incentives are accounted for as a reduction of
revenue in accordance with EITF 01-9, Accounting for Consideration Given by a Vendor to a Customer (Including a
Reseller of the Vendor’s Products).

Cash received in advance from customers is recorded as customer deposits. The unused cash balances
remaining in customers’ accounts are included as a liability of our company. Deferred revenue is recorded when the
services are provided before the applicable revenue recognition criteria set forth in SAB 104 are fulfilled.

Share-based Compensation Expenses

We account for share-based compensation in accordance with SFAS No. 123R, Share-Based Payment, or
SFAS 123R. Under the provisions of SFAS 123R, share-based compensation cost is estimated at the grant date
based on the award’s fair value as calculated by the Black-Scholes-Merton (BSM) option-pricing model and is
recognized as expense over the requisite service period. The BSM model requires various highly judgmental
assumptions including volatility and expected option life. If any of the assumptions used in the BSM model change
significantly, share-based compensation expense may differ materially in the future from that recorded in the
current period. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for

67

those shares expected to vest. We estimate the forfeiture rate based on historical experience. Further, to the extent
our actual forfeiture rate is different from our estimate, stock-based compensation expense is adjusted accordingly.

Income Taxes

We are subject to income taxes in the PRC and Japan. Significant judgment is required in evaluating our

uncertain tax positions and determining our provision for income taxes.

The Financial Accounting Standard Board Interpretation No. 48, Accounting for Uncertainty in Income
Taxes — an interpretation of FASB Statement No. 109, or FIN 48, contains a two-step approach to recognizing and
measuring uncertain tax positions accounted for in accordance with Statement of Financial Accounting Standards
No. 109, Accounting for Income Taxes, or SFAS 109. The first step is to evaluate the tax position for recognition by
determining if the weight of available evidence indicates that it is more likely than not that the position will be
sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to
measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.

Although we believe we have adequately reserved for our uncertain tax positions, no assurance can be given
that the final tax outcome of these matters will not be different. In general, tax filings within the last five years are
subject to examination by the PRC and Japanese tax authorities. Accordingly, our PRC subsidiaries’ and affiliated
entities’ tax filings for the tax years 2004 to 2008 and our Japanese subsidiary’s tax filings for the tax years 2006 to
2008 remain open to examination by the respective taxing jurisdictions.

We do not believe that net deferred tax assets related with our Japan and Hong Kong operations are more likely
than not to be realized. Consequently, we have provided full valuation allowances on the related net deferred tax
assets.

Allowance for Doubtful Accounts

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential
uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer
probable. Bad debts are written off as incurred. We generally do not require collateral from our customers.

We maintain allowances for doubtful accounts for estimated losses resulting from the failure of customers to
make payments on time. We review the accounts receivable on a periodic basis and make general and specific
allowances when there is doubt as to the collectibility of individual balances. In evaluating the collectibility of
individual receivable balances, we consider many factors, including the age of the balance, the customer’s past
payment history, its current credit-worthiness and current economic trends.

Impairment of Long-Lived Assets

We evaluate long-lived assets, such as property and equipment and purchased or internally developed
intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the
carrying value of an asset may not be recoverable in accordance with SFAS No. 144, Accounting for the Impairment
or Disposal of Long-Lived Assets. We assess the recoverability of an asset group based on the undiscounted future
cash flows the asset group is expected to generate and recognize an impairment loss when the estimated
undiscounted future cash flows expected to result from the use of the asset group plus net proceeds expected
from the disposition of the asset group, if any, are less than the carrying value of the asset group. If we identify an
impairment, we reduce the carrying amount of the asset group to its estimated fair value based on a discounted cash
flow approach or, when available and appropriate, to comparable market values. We use estimates and judgments in
our impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any
impairment charges could be different.

Impairment of Goodwill and Intangible Assets with Indefinite Life

We assess goodwill and non-amortized intangible assets for impairment in accordance with SFAS No. 142,
Goodwill and Other Intangible Assets, which requires that goodwill and non-amortized intangible assets be tested
for impairment at the “reporting unit level” at least annually and more frequently upon the occurrence of certain

68

BOM  H03242  069.00.00.00  9

events, as defined by SFAS No. 142. Intangible assets with an indefinite useful life are not amortized. In accordance
with this policy, one of the domain name assets, which was acquired in July 2006, and the “Baidu” trademark are not
subject to amortization, as the remaining useful life is indefinite. Based on our business activities and operational
management perspective, we have determined that there is only one reporting unit. Goodwill and non-amortized
intangible assets were tested for impairment in the annual impairment tests on December 31 in each of the years
2006, 2007, and 2008 using the two-step process required by SFAS No. 142. First, we reviewed the carrying amount
of the reporting unit compared to the “fair value” of the reporting unit based on quoted market prices of our ordinary
shares. If such comparison reflected potential impairment, we would then prepare the discounted cash flow
analyses. Such analyses are based on cash flow assumptions that are consistent with the plans and estimates being
used to manage the business. An excess of the carrying value of the goodwill over the fair value of the goodwill
would indicate that the goodwill may be impaired. Finally, if we determined that goodwill may be impaired, the
“implied fair value” of the goodwill, as defined by SFAS No. 142, would be compared to its carrying amount to
determine the impairment loss, if any. There has been no impairment of goodwill in any of the years presented.

Recent Accounting Pronouncements

In December 2007, the Financial Accounting Standard Board, or FASB, issued SFAS Statement No. 141
(revised 2007), Business Combinations, or SFAS 141R. This statement establishes principles and requirements for
how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities
assumed, any non-controlling interest in the acquiree and the goodwill acquired. SFAS 141R also establishes
disclosure requirements to enable the evaluation of the nature and financial effects of the business combination.
SFAS 141R is effective for fiscal years beginning on or after December 15, 2008. The impact of the adoption of
SFAS 141R on our consolidated results of operations and financial condition will be largely dependent on the size
and nature of the business combinations completed after the adoption of this statement.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial
Statements — an amendment of ARB No. 51, or SFAS 160. This statement affects the entities that have an
outstanding non-controlling interest in one or more subsidiaries or that deconsolidate a subsidiary. SFAS 160 is
effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. We
do not expect that the adoption of SFAS 160 will have a material impact on our consolidated results of operations
and financial condition.

In February 2008, the FASB issued FASB Staff Position, or FSP, No. FAS 157-1, Application of FASB
Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value
Measurements for Purposes of Lease Classification or Measurement under Statement 13 and FSP No. 157-2,
Effective Date of FASB Statement No. 157, which collectively remove certain leasing transactions from the scope of
SFAS 157 and partially delay the effective date of SFAS 157 for one year for certain non-financial assets and
liabilities. In October 2008, the FASB issued FSP No. 157-3, Determining the Fair Value of a Financial Asset When
the Market for That Asset Is Not Active, which clarifies the application of SFAS No. 157 in an inactive market and
illustrates how an entity would determine fair value when the market for a financial asset is not active. We do not
expect that the adoption of FSP No. 157-1, FSP No. 157-2 and FSP No. 157-3 will have a material impact on our
consolidated results of operations and financial condition.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging
Activities, an amendment of FASB Statement No. 133, or SFAS 161. SFAS 161 applies to all derivative instruments
and related hedged items accounted for under SFAS No. 133, Accounting for Derivative Instruments and Hedging
Activities, or SFAS 133. SFAS 161 requires entities to provide greater transparency about how and why an entity
uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS 133
and its related interpretations, and how derivative instruments and related hedged items affect an entity’s financial
position, results of operations and cash flows. SFAS 161 is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. We do not expect the adoption of SFAS 161 to have any
material effect on our consolidated results of operations and financial condition.

In April 2008, the FASB issued FSP No. FAS 142-3, Determination of the Useful Life of Intangible Assets, or
FSP 142-3. FSP142-3 amends the factors an entity should consider in developing renewal or extension assumptions

69

used in determining the useful life of recognized intangible assets under SFAS 142, and applies to (1) intangible
assets that are acquired individually or with a group of other assets and (2) both intangible assets acquired in
business combinations and asset acquisitions. FSP 142-3 also requires entities to disclose information for all
intangible assets, recognized as of and subsequent to the effective date of FSP 142-3 to provide effects of the entity’s
intent or ability to renew or extend the arrangement associated with the intangible assets on expected cash flows
associated with the intangible assets. FSP 142-3 is effective for intangible assets acquired after December 15, 2008
and early application is prohibited. We are currently evaluating whether the adoption of FSP 142-3 will have a
significant effect on our consolidated results of operations and financial condition.

In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles, or
SFAS 162. SFAS 162 identifies the sources of accounting principles and the framework for selecting the principles
used in the preparation of financial statements of nongovernmental entities that are presented in conformity with
U.S. GAAP (the GAAP hierarchy). SFAS 162 became effective November 15, 2008. We do not expect the adoption
of SFAS 162 to have a material effect on our consolidated results of operations and financial condition.

In June 2008, the EITF issued EITF Issue No. 07-5, Determining Whether an Instrument (or Embedded
Feature) Is Indexed to an Entity’s Own Stock, or EITF 07-5. EITF 07-5 clarifies the determination of whether an
instrument (or an embedded feature) is indexed to an entity’s own stock, which would qualify as a scope exception
under SFAS 133, Accounting for Derivative Instruments and Hedging Activities. EITF 07-5 is effective for financial
statements issued for fiscal years beginning after December 15, 2008. EITF 07-5 does not permit early adoption for
an existing instrument. We do not expect the adoption of EITF 07-5 will have a material effect on our consolidated
results of operations and financial condition.

In June 2008, the FASB issued FSP EITF Issue No. 03-6-1, Determining Whether Instruments Granted in
Share-Based Payment Transactions Are Participating Securities, or FSP EITF 03-6-1. FSP EITF 03-6-1 clarifies
that share-based payment awards that entitle their holders to receive non-forfeitable dividends or dividend
equivalents before vesting should be considered participating securities. FSP EITF 03-6-1 is effective for fiscal
years beginning after December 15, 2008 on a retrospective basis . We have not granted any share-based payment
awards that contain non-forfeitable rights to dividends or dividend equivalents before vesting since incorporation.
We are currently evaluating the potential impact, if any, of the adoption of FSP EITF 03-6-1 on our consolidated
results of operations and financial condition.

In November 2008, the FASB ratified EITF Issue No. 08-7, Accounting for Defensive Intangible Assets, or
EITF 08-7. EITF 08-7 applies to defensive intangible assets, which are acquired intangible assets that the acquirer
does not intend to actively use but intends to hold to prevent its competitors from obtaining access to them. As these
assets are separately identifiable, EITF 08-7 requires an acquiring entity to account for defensive intangible assets
as a separate unit of accounting. Defensive intangible assets must be recognized at fair value in accordance with
SFAS 141R and SFAS 157. EITF 08-7 is effective for defensive intangible assets acquired in fiscal years beginning
on or after December 15, 2008. We are currently evaluating the potential impact, if any, of the adoption of EITF 08-7
on our consolidated results of operations and financial condition.

B. Liquidity and Capital Resources

Our principal sources of liquidity are our cash, cash equivalents and short-term investments, which comprise
primarily of fixed rate and adjustable rate fixed income investments maturing within one year, as well as the cash
flow generated from our operations. We believe that our current cash, cash equivalents, short-term investments and
anticipated cash flow from operations will be sufficient to meet our anticipated cash needs, including our cash needs
for working capital and capital expenditures for at least the next 12 months. We may, however, require additional
cash due to changing business conditions or other future developments, including any investments or acquisitions
we may decide to pursue. If our existing cash is insufficient to meet our requirements, we may seek to sell additional
equity securities, debt securities or borrow from banks.

Operating Activities

Net cash generated from operating activities increased to RMB1.7 billion (US$255.9 million) in 2008 from
RMB935.2 million in 2007. This increase was mainly attributable to several factors, including (i) the substantial
increase in net income to RMB1.0 billion (US$153.6 million) in 2008 compared to net income of RMB629.0 million
in 2007; (ii) the increase in add-back of non-cash expenses, mainly consisting of share-based compensation and
depreciation expenses; (iii) the increase in customer deposits resulting from the increased number of P4P
customers; and (iv) the increase in accrued expenses and other liabilities, partially offset by an increase of
RMB47.8 million (US$7.0 million) in other non-current assets primarily due to deposits for new offices we rent.

Net cash generated from operating activities increased to RMB935.2 million in 2007 from RMB440.8 million
in 2006. This increase was mainly attributable to several factors, including (i) the substantial increase in net income
to RMB629.0 million in 2007 compared to net income of RMB301.8 million in 2006; (ii) the increase in add-back
of non-cash expenses, mainly consisting of share-based compensation and depreciation expenses; (iii) the increase
in customer deposits resulting from the increased number of P4P customers; and (iv) the increase in accrued
expenses and other liabilities, partially offset by an increase of RMB24.6 million in other non-current assets
primarily due to deposits for new offices we rent.

Investing Activities

Net cash used in investing activities decreased from RMB713.2 million in 2007 to RMB661.1 million
(US$96.9 million) in 2008, primarily due to less spending on acquisition of fixed assets and no further spending on
land use right for our new corporate headquarters in 2008.

Net cash used in investing activities increased from RMB208.9 million in 2006 to RMB713.2 million in 2007,
primarily due to our purchase of additional servers in China and Japan, cash used in acquisitions (including
investments in several privately held entities for less than 5% of equity interests in each of these entities), investment
in marketable securities, additional payment for the acquisition of the land use right for our new corporate
headquarters, and investment in connection with the construction of the corporate headquarters.

Financing Activities

Net cash outflow from financing activities was RMB35.6 million (US$5.2 million) in 2008, compared to a net
cash inflow of RMB40.7 million in 2007, primarily due to an upfront cash payment of US$10 million made under a
structured share repurchase transaction entered into in December 2008, partially offset by the proceeds received
from exercise of our share options in 2008. Net cash inflow from financing activities increased to RMB40.7 million
in 2007 from RMB32.2 million in 2006 due to the net proceeds received from the exercise of our share options in
2007.

We are a holding company with no operations of our own. We conduct our operations in China primarily
through our indirect wholly-owned subsidiaries, Baidu Online, Baidu China and Baidu Times, and our consolidated
affiliated entities, Baidu Netcom and Beijing Perusal. As a result, our ability to pay dividends and to finance any
debt we may incur depends upon dividends paid by Baidu Online, Baidu China and Baidu Times and license and
service fees paid by Baidu Netcom and Beijing Perusal. If Baidu Online, Baidu China, Baidu Times or any newly
formed subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict
their ability to pay dividends to us. In addition, our PRC subsidiaries are permitted to pay dividends to us only out of
their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Under
PRC law, our subsidiaries and affiliated entities in the PRC are required to set aside at least 10% of their after-tax
profit each year to fund a statutory reserve fund until the amount of the reserve fund reaches 50% of such entity’s
registered capital. Although these statutory reserve funds can be used, among other ways, to increase the registered
capital and eliminate future losses in excess of retained earnings of the respective companies, these reserve funds
are not distributable as cash dividends except in the event of a solvent liquidation of the companies. See Note 14 to
our consolidated financial statements.

Capital Expenditures

We made capital expenditures of RMB127.5 million, RMB569.1 million and RMB417.9 million
(US$61.3 million) in 2006, 2007 and 2008, respectively, representing 15.2%, 32.6% and 13.1% of our total
revenues, respectively. Our capital expenditures were used primarily to purchase servers, network equipment and
other computer hardware for our business, the acquisition of the land use right and the construction for our new
corporate headquarters. We funded our capital expenditures primarily with net cash flow from operating activities.

In late 2005, we entered into an agreement to acquire the land use right in Beijing to build our new corporate
headquarters with a floor space of approximately 44,000 square meters. The floor space was increased to
59,000 square meters in 2006. We made a total payment of RMB97.6 million for the land use right. We have
obtained necessary governmental approvals for the proposed development and use of the land, and our new office
building is currently under construction. Our capital expenditures in connection with construction of our office
building were RMB102.1 million in 2007 and RMB172.3 million (US$25.3 million) in 2008, excluding the above-
mentioned payment for land use right. Our capital expenditures may increase substantially in the near term as our
business continues to grow and as we expand and improve our network infrastructure.

C. Research and Development

We have a team of experienced engineers who are mostly based at our headquarters in Beijing. We recruit most
of our engineers locally and have established various recruiting and training programs with leading universities in
China. We have also recruited experienced engineers from overseas. We compete aggressively for engineering
talent to help us address challenges such as Chinese language processing, information retrieval and high perfor-
mance computing. In each of the three years ended December 31, 2006, 2007 and 2008, our research and
development expenditures, including share-based compensation expenses for research and development staff, were
RMB79.2 million, RMB140.7 million and RMB286.3 million (US$42.0 million), representing 9.5%, 8.1% and
9.0% of our total revenues for 2006, 2007 and 2008, respectively.

D. Trend Information

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands,
commitments or events for the year ended December 31, 2008 that are reasonably likely to have a material adverse
effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed
financial information to be not necessarily indicative of future operating results or financial conditions.

E. Off-Balance Sheet Arrangements

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations
of any third parties. We have not entered into any off-balance sheet derivative instruments. Furthermore, we do not
have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit,

provides financing, liquidity, market risk or credit support to us or engages in leasing, hedging or research and
development services with us.

The following paragraphs summarize the key terms of our 2000 option plan, which was amended and restated

on December 16, 2008, and our newly adopted 2008 share incentive plan.

2000 Option Plan

Types of Awards. We may grant the following types of awards under our 2000 option plan:

(cid:129) our ordinary shares;

(cid:129) options to purchase our ordinary shares; and

(cid:129) any other securities with value derived from the value of our ordinary shares.

Plan Administration. Our board of directors, or a committee designated by our board of directors, admin-
isters our 2000 option plan. In each case, our board of directors or the committee, will determine the provisions and
terms and conditions of each award grant. These include, among other things, the option vesting schedule,
repurchase provisions, rights of first refusal, forfeiture provisions, form of payment upon settlement of an award,
payment contingencies and satisfaction of any performance criteria.

Award Agreement. Awards granted under our 2000 option plan are evidenced by an award agreement that
sets forth the terms, conditions and limitations for each award. In addition, in the case of options, the award
agreement also specifies whether the option constitutes an incentive stock option, or ISO, or a non-qualifying stock
option.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our
related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest.
However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon occur-
rence of a change-of-control corporate transaction in which the successor entity does not assume our outstanding
awards under our 2000 option plan. In such event, each outstanding award will become fully vested and
immediately exercisable, the transfer restrictions on the awards will be released (other than those applicable to
ISOs), and the repurchase or forfeiture rights will terminate immediately before the date of the change-of-control
transaction. If the successor entity assumes our outstanding awards and later terminates the grantee’s employment
or service without cause, or if the grantee resigns voluntarily with good cause within 12 months of the
change-of-control transaction, the outstanding awards automatically become fully vested and exercisable.

Exercise Price and Term of Awards.

If we grant an ISO to an employee, who, at the time of that grant, owns
shares representing more than 10% of the voting power of all classes of our share capital, the exercise price cannot
be less than 110% of the fair market value of our ordinary shares on the date of that grant. To the extent not
prohibited by applicable law or exchange rules, a downward adjustment of the exercise price per share subject to an

76

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:23 NO MARKS 

NEXT PCN: 078.00.00.00 -- Page is valid, no graphics

BOM  H03242  077.00.00.00  11

outstanding option may be made in the absolute discretion of the plan administrator without the approval of our
shareholders or the affected grantees.

The term of each award is stated in the award agreement. The term may not exceed ten years from the date of
the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of
the voting power of our share capital.

Vesting Schedule.

In general, the plan administrator determines, or the award agreement specifies, the
vesting schedule. Options generally vest over a four-year period beginning from one year after the grant date. The
award agreements may provide that grantees may elect at any time during their employment or service to exercise
any part or all of the awards prior to full vesting of the awards. But such early exercise may be subject to a
repurchase right as determined by the plan administrator. When an optionee’s employment or service is terminated,
the optionee may exercise his or her options that have vested as of the termination date within three months of
termination or as determined by our plan administrator.

Repurchase Rights.

If an award agreement provides for repurchase rights upon termination of a grantee’s
employment or service, it must (or may, with respect to awards granted to officers, directors or consultants) provide
that (i) such repurchase right must be exercised within 90 days of termination of the grantee’s employment or
service (or, in the case of exercise of awards after termination of the grantee’s employment or service, within
90 days following such exercise), (ii) the repurchase price must be equal to the original purchase price paid by the
grantee for each such share, and (iii) the right to repurchase will lapse at the rate of at least 20% of the shares subject
to the award per year over five years from the date the award is granted (without respect to the date the award was
exercised or became exercisable).

Amendment and Termination. Our board of directors may at any time amend, suspend or terminate our 2000
option plan. Amendments to our 2000 option plan are subject to shareholder approval, to the extent required by law,
or by stock exchange rules or regulations. Any amendment, suspension or termination of our 2000 option plan must
not adversely affect awards already granted without written consent of the recipient of such awards. Unless
terminated earlier, our 2000 option plan shall continue in effect for a term of ten years from the date of adoption.

2008 Share Incentive Plan

Types of Awards. We may grant the following types of awards under our 2008 share incentive plan:

(cid:129) options;

(cid:129) restricted shares;

(cid:129) restricted share units; and

(cid:129) any other form of award granted to a participant pursuant to the 2008 plan.

Plan Administration. The compensation committee of our board of directors administers our 2008 share
incentive plan, but may delegate to a committee of one or more members of our board of directors the authority to
grant or amend awards to participants other than independent directors and executive officers. The compensation
committee will determine the provisions and terms and conditions of each award grant, including, but not limited to,
the exercise price, the grant price or purchase price, any restrictions or limitations on the award, any schedule for
lapse of forfeiture restrictions or restrictions on the exercisability of an award, and accelerations or waivers thereof,
any provisions related to non-competition and recapture of gain on an award, based in each case on such
considerations as the committee in its sole discretion determines. The compensation committee has the sole
power and discretion to cancel, forfeit or surrender an outstanding award (whether or not in exchange for another
award or combination or awards).

Award Agreement. Awards granted under our 2008 share incentive plan are evidenced by an award
agreement that sets forth the terms, conditions and limitations for each award which may include the term of
an award, the provisions applicable in the event the participant’s employment or service ends, and our authority to
unilaterally or bilaterally amend, modify, suspend, cancel or rescind an award.

Eligibility. We may grant awards to employees, directors and consultants of our company or any of our
related entities, which include our subsidiaries or any entities in which we hold a substantial ownership interest.
However, we may grant ISOs only to our employees and employees of our majority-owned subsidiaries.

Acceleration of Awards upon Corporate Transactions. The outstanding awards will accelerate upon occur-
rence of a change-of-control corporate transaction in which the successor entity does not assume our outstanding
awards under our 2008 share incentive plan, provided that the plan participant remains an employee, consultant or
member of our board of directors on the effective date of the corporate transaction. In such event, each outstanding
award will become fully exercisable and all forfeiture restrictions on such award will lapse immediately prior to the
specified effective date of the corporate transaction.

If the successor entity assumes our outstanding awards and later terminates the grantee’s employment or
service without cause, or if the grantee resigns voluntarily with good reason within 12 months of the corporate
transaction, the outstanding awards automatically will become fully vested and exercisable. The compensation
committee may also, in its sole discretion, upon or in anticipation of a corporate transaction, accelerate awards,
purchase the awards from the plan participants, replace the awards, or provide for the payment of the awards in cash.

Exercise Price and Term of Awards. The exercise price per share subject to an option may be amended or
adjusted in the absolute discretion of the compensation committee, the determination of which shall be final,
binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment
of the exercise prices of options mentioned in the preceding sentence shall be effective without the approval of our
shareholders or the approval of the affected grantees. If we grant an ISO to an employee, who, at the time of that
grant, owns shares representing more than 10% of the voting power of all classes of our share capital, the exercise
price cannot be less than 110% of the fair market value of our ordinary shares on the date of that grant. The
compensation committee will determine the time or times at which an option may be exercised in whole or in part,
including exercise prior to vesting. The term may not exceed ten years from the date of the grant, except that five
years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of our
share capital.

Restricted Shares and Restricted Share Unites. The compensation committee is also authorized to make
awards of restricted shares and restricted share units. Except as otherwise determined by the compensation
committee at the time of the grant of an award or thereafter, upon termination of employment or service during the
applicable restriction period, restricted shares that are at the time subject to restrictions shall be forfeited or
repurchased in accordance with the respective award agreements. At the time of grant for restricted share units, the
compensation committee shall specify the date on which the restricted share units shall become fully vested and
nonforfeitable, and may specify such conditions to vesting as it deems appropriate.

Amendment and Termination. With the approval of our board of directors, the compensation committee may
at any time amend, suspend or terminate our 2008 share incentive plan. Amendments to our 2008 share incentive
plan are subject to shareholder approval, to the extent required by law, or by stock exchange rules or regulations.
Any amendment, suspension or termination of our 2008 share incentive plan must not adversely affect in any
material way awards already granted without written consent of the recipient of such awards. Unless terminated
earlier, our 2008 share incentive plan shall continue in effect for a term of ten years from the date of adoption.

C. Board Practices

Board of Directors

Our board of directors has five directors. A director is not required to hold any shares in the company by way of
qualification. A director may vote with respect to any contract, proposed contract or arrangement in which he is
materially interested. A director may exercise all the powers of the company to borrow money, mortgage its
undertakings, property and uncalled capital, and issue debentures or other securities whenever money is borrowed
or as security for any obligation of the company or of any third party. The remuneration to be paid to the directors are
determined by the board of directors. There is no age limit requirement for directors.

Committees of the Board of Directors

We have three committees under the board of directors: an audit committee, a compensation committee and a
corporate governance and nominating committee. We have adopted a charter for each of the three committees.

Audit Committee

Our audit committee consists of Messrs. William Decker, James Ding and Greg Penner, all of whom satisfy the
“independence” requirements of Rule 4350 of the Nasdaq Stock Market Marketplace Rules and Rule 10A-3 under
the Securities Exchange Act of 1934, as amended. Our board of directors has determined that Mr. Decker is an audit
committee financial expert as defined in the instructions to Item 16A of the Form 20-F. The audit committee
oversees our accounting and financial reporting processes and the audits of the financial statements of our company.
The audit committee is responsible for, among other things:

(cid:129) appointing, retaining and overseeing the work of the independent auditors, including resolving disagree-

ments between the management and the independent auditors relating to financial reporting;

(cid:129) pre-approving all auditing and non-auditing services permitted to be performed by the independent auditors;

(cid:129) reviewing annually the independence and quality control procedures of the independent auditors;

(cid:129) reviewing and approving all proposed related party transactions;

(cid:129) discussing the annual audited financial statements with the management;

(cid:129) meeting separately with the independent auditors to discuss critical accounting policies, management letters,
recommendations on internal controls, the auditor’s engagement letter and independence letter and other
material written communications between the independent auditors and the management; and

(cid:129) attending to such other matters that are specifically delegated to our audit committee by our board of

directors from time to time.

In 2008, our audit committee held meetings and passed resolutions by unanimous written consent five times.

Compensation Committee

Our compensation committee consists of Messrs. James Ding and Greg Penner, both of whom satisfy the
“independence” requirements of Rule 4350 of the Nasdaq Stock Market Marketplace Rules. The compensation
committee assists the board in reviewing and approving our compensation structure, including all forms of
compensation relating to our directors and executive officers. Our chief executive officer may not be present at any
committee meeting while his compensation is deliberated. The compensation committee is responsible for, among
other things:

(cid:129) reviewing and approving executive compensation;

(cid:129) reviewing periodically and approving any long-term incentive compensation or equity plans, programs or

similar arrangements, annual bonuses, employee pension and welfare benefit plans;

(cid:129) determining our policy with respect to change of control or “parachute” payments; and

(cid:129) managing and reviewing director and executive officer indemnification and insurance matters.

In 2008, our compensation committee held meeting and passed resolutions by unanimous written consent

once.

Corporate Governance and Nominating Committee

Our corporate governance and nominating committee consists of Messrs. James Ding and Greg Penner, both of
whom satisfy the “independence” requirements of Rule 4350 of the Nasdaq Stock Market Marketplace Rules. The
corporate governance and nominating committee assists the board of directors in selecting individuals qualified to

become our directors and in determining the composition of the board and its committees. The corporate
governance and nominating committee is responsible for, among other things:

(cid:129) recommending to the board nominees for election or re-election to the board or for appointments to fill any

vacancies;

(cid:129) reviewing annually the performance of each incumbent director in determining whether to recommend such

director for an additional term;

(cid:129) overseeing the board in the board’s annual review of its own performance and the performance of the

management; and

(cid:129) considering, preparing and recommending to the board such policies and procedures with respect to
corporate governance matters as may be required or required to be disclosed under the applicable laws or
otherwise considered to be material.

In 2008, our corporate governance and nominating committee passed resolutions by unanimous written

consent once.

Terms of Directors and Executive Officers

All directors hold office until their successors have been duly elected and qualified. Director nomination is
subject to the approval of our corporate governance and nominating committee. Our shareholders may remove any
director by ordinary resolution and may in like manner appoint another person in his stead. A valid ordinary
resolution requires a majority of the votes cast at a shareholder meeting that is duly constituted and meets the
quorum requirement. Officers are elected by and serve at the discretion of the board of directors.

D. Employees

We had 3,113, 6,252 and 6,387 employees as of December 31, 2006, 2007 and 2008, respectively. As of
December 31, 2008, we had 6,387 employees, including 492 in management and administration, 1,381 in research
and development, 659 in operation and service, and 3,855 in sales and marketing. We also hire temporary
employees and contractors from time to time. Our employees are not covered by any collective bargaining
agreement. We consider our relations with our employees to be good.

E. Share Ownership

March 31, 2009 by:

filing).

Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders of Class A
ordinary shares are entitled to one vote per share, while holders of Class B ordinary shares are entitled to 10 votes
per share. We issued Class A ordinary shares represented by our ADSs in our initial public offering in 2005. Holders
of our Class B ordinary shares may choose to convert their Class B ordinary shares into the same number of Class A
ordinary shares at any time. We are not aware of any arrangement that may, at a subsequent date, result in a change
of control of our company. See “Item 3D. Key Information — Risk Factors — Risks Related to Our ADSs — Our
dual-class ordinary share structure with different voting rights could discourage others from pursuing any change of
control transactions that holders of our Class A ordinary shares and ADSs may view as beneficial.”

As of March 31, 2009, 34,552,169 of our ordinary shares were issued and outstanding. To our knowledge,
approximately 78% of our total outstanding ordinary shares were held by five record shareholders in the United
States, including approximately 74% held by The Bank of New York Mellon, the depositary of our ADS program.
The number of beneficial owners of our ADSs in the United States is likely to be much larger than the number of
record holders of our ordinary shares in the United States.

Contractual Arrangements with Baidu Netcom and Its Shareholders

PRC law currently limits foreign equity ownership of companies that provide Internet content and advertising
businesses. To comply with these foreign ownership restrictions, we operate our websites and provide online
advertising services in China through a series of contractual arrangements with Baidu Netcom and its shareholders,
Robin Yanhong Li and Eric Yong Xu. In March 2005, we restructured these contractual arrangements as follows:

Exclusive Technology Consulting and Services Agreement. Pursuant to the exclusive technology
consulting and services agreement between Baidu Online and Baidu Netcom, Baidu Online has the exclusive
right to provide to Baidu Netcom technology consulting and services related to the maintenance of servers,

software development and design of advertisements. Baidu Online also seconds employees to Baidu Netcom
for whom Baidu Netcom bears the costs and expenses. Baidu Online owns the intellectual property rights
related to the software developed by Baidu Online for Baidu Netcom. Baidu Netcom pays monthly service fees
to Baidu Online based upon a pre-agreed formula, which takes into account the number of monthly page views
and the basic fee for every one thousand page views of advertisements displayed on our websites. The basic fee
for every one thousand page views is subject to periodic adjustment. The current rate of the basic fee is
RMB1.444. The term of this agreement is ten years from the date thereof.

Business Cooperation Agreement. Pursuant to the business cooperation agreement between Baidu
Netcom and Baidu Online, Baidu Netcom provides Internet information services, Internet advertising services
and related services to Baidu Online to enable Baidu Online to provide P4P services on the websites owned and
operated by Baidu Netcom, and Baidu Online provides search engine technology services to Baidu Netcom.
Baidu Online agrees to pay a monthly fee of RMB10,000 to Baidu Netcom. The term of this agreement is ten
years from the date thereof.

Operating Agreement. Pursuant to the operating agreement among Baidu Online, Baidu Netcom and
the shareholders of Baidu Netcom, Baidu Online provides guidance and instructions on Baidu Netcom’s daily
operations and financial affairs. The shareholders of Baidu Netcom must designate the candidates recom-
mended by Baidu Online as their representatives on Baidu Netcom’s board of directors. Baidu Online has the
right to appoint senior executives of Baidu Netcom. In addition, Baidu Online agrees to guarantee Baidu
Netcom’s performance under any agreements or arrangements relating to Baidu Netcom’s business arrange-
ments with any third party. Baidu Netcom, in return, agrees to pledge its accounts receivable and all of its assets
to Baidu Online. Moreover, Baidu Netcom agrees that without the prior consent of Baidu Online, Baidu
Netcom will not engage in any transactions that could materially affect the assets, liabilities, rights or
operations of Baidu Netcom, including, without limitation, incurrence or assumption of any indebtedness, sale
or purchase of any assets or rights, incurrence of any encumbrance on any of its assets or intellectual property
rights in favor of a third party or transfer of any agreements relating to its business operation to any third party.
The term of this agreement is ten years from the date thereof.

Software License Agreement. Under the software license agreement, Baidu Online granted Baidu
Netcom a non-exclusive, non-assignable and non-transferable right to use “Baidu Chinese Search Engine” and
“Baidu Internet P4P System” software. Baidu Netcom can only use the software on its designated operating
systems to process its internal data. The annual license fee for each software is RMB5.0 million. When
deciding the amount of the annual license fee, Baidu Online and Baidu Netcom considered several factors,
including functionality and quality of the software, past and ongoing research and development costs incurred
by Baidu Online in developing and upgrading the software, license fees of other portal search software
applications, Baidu Online’s enterprise search application license fees, and Baidu Netcom’s financial
resources and projected operating results. The term of the license agreement is five years from the date thereof.

Other License Agreements. Under these license agreements, Baidu Online granted Baidu Netcom the
exclusive right to use the registered domain names and trademarks owned by Baidu Online and the web layout
owned by Baidu Online for the websites operated by Baidu Netcom. The annual license fee under each license
agreement is RMB10,000, subject to certain adjustments. The term of each license agreement is five years
from the date thereof. The domain name license agreement was terminated upon the completion of the
transfers of certain domain names primarily used in our business from our company or Baidu Online to Baidu
Netcom in May 2008. After the transfers of certain trademarks (including pending trademark applications)
from Baidu Online to Baidu Netcom are completed, the trademark license agreement will be amended or
terminated. We do not expect the termination of these license agreements to have any material effect on our
operations.

Proxy Agreement. Pursuant to the proxy agreement among Baidu Online, Baidu Netcom and the
shareholders of Baidu Netcom, the shareholders of Baidu Netcom agree to entrust all the rights to exercise their
voting power to the person(s) appointed by Baidu Online. The term of the proxy agreement is 10 years from the
date thereof.

Equity Pledge Agreement. Under the equity pledge agreement between the shareholders of Baidu
Netcom and Baidu Online, the shareholders of Baidu Netcom pledged all of their equity interests in Baidu
Netcom to Baidu Online to guarantee their obligations under the loan agreement and Baidu Netcom’s
performance of its obligations under the technology consulting agreement. If Baidu Netcom or either of its
shareholders breaches its respective contractual obligations, Baidu Online, as pledgee, will be entitled to
certain rights, including the right to sell the pledged equity interests. The shareholders of Baidu Netcom agreed
not to dispose of the pledged equity interests or take any actions that would prejudice Baidu Online’s interest.
The equity pledge agreement will expire two years after expiration of the term for fulfillment by Baidu Netcom
and its shareholders of their respective obligations under the exclusive technology consulting service
agreement and the loan agreement.

Exclusive Equity Purchase Option Agreement. Under the exclusive equity purchase option agreement
between the shareholders of Baidu Netcom and Baidu Online, the shareholders of Baidu Netcom irrevocably
granted Baidu Online or its designated person an exclusive option to purchase, to the extent permitted under
PRC law, all or part of the equity interests in Baidu Netcom for the cost of the initial contributions to the
registered capital or the minimum amount of consideration permitted by applicable PRC law. Baidu Online or
its designated person has sole discretion to decide when to exercise the option, whether in part or in full. The
term of this agreement is ten years from the date thereof.

Loan Agreement. Under the loan agreement between the shareholders of Baidu Netcom and Baidu
Online, the parties confirmed that Baidu Online had made an RMB2.0 million interest-free loan to the
shareholders of Baidu Netcom solely for the latter to fund the capitalization of Baidu Netcom. The loan can be
repaid only with the proceeds from sale of the shareholder’s equity interest in Baidu Netcom to Baidu Online.
The term of the agreement is ten years from the date thereof.

Irrevocable Power of Attorney. The shareholders of Baidu Netcom have each executed an irrevocable
power of attorney to appoint Xuyang Ren as their attorney-in-fact to vote on their behalf on all Baidu Netcom
matters requiring shareholder approval. The appointment of Xuyang Ren as attorney-in-fact will terminate if
Xuyang Ren is no longer employed by Baidu Online. The term of the power of attorney is ten years from the
date thereof.

In February 2006 and March 2008, we extended two additional interest-free loans of RMB8.0 million and
RMB90.0 million (US$13.2 million), respectively, to Robin Yanhong Li for the sole purpose of increasing the
registered capital of Baidu Netcom. In connection with each loan, we entered into the following agreements with
Mr. Li:

(cid:129) a loan agreement;

(cid:129) an equity pledge agreement between Robin Yanhong Li and Baidu Online; and

(cid:129) an exclusive equity purchase option agreement among Robin Yanhong Li, Baidu Netcom and Baidu Online.

The terms of these agreements are similar to the terms of the original agreements between Baidu Online and
the shareholders of Baidu Netcom entered into in March 2005. In addition, under the terms of the original proxy
agreement entered into in March 2005, Mr. Li is required to entrust all the rights to exercise the additional voting
power he acquired as a result of his additional investment in the registered capital of Baidu Netcom to the person(s)
appointed by Baidu Online.

Contractual Arrangements with Beijing Perusal and Its Shareholders

We entered into a series of contractual arrangements with Beijing Perusal and its shareholders in 2006 and,

with respect to the proxy agreements, 2008. These agreements include:

(cid:129) loan agreements for interest-free loans in an aggregate amount of RMB1.0 million to the shareholders of

Beijing Perusal;

(cid:129) exclusive equity purchase option agreements among Beijing Perusal, Baidu Online and the shareholders of

Beijing Perusal;

(cid:129) a proxy agreement between the shareholders of Beijing Perusal and Baidu Online;

(cid:129) an exclusive technology consulting and services agreement between Beijing Perusal and Baidu Online;

(cid:129) various license agreements between Beijing Perusal and Baidu Online, including domain name license
agreements, trademark license agreements and webpage copyright license agreements. The domain name
license agreement was terminated in May 2008 because Beijing Perusal already owns the domain names
primarily used in its business. After the transfers of certain pending trademark applications from Baidu
Online to Beijing Perusal are completed, the trademark license agreement will be terminated. We do not
expect the termination of these license agreements to have any material effect on our operations.

The terms of these contractual arrangements are similar to the terms of our contractual arrangements with

Baidu Netcom and its shareholders.

Contractual Arrangements with BaiduPay and Its Individual Shareholder

We entered into a series of contractual arrangements with BaiduPay and its individual shareholder in 2008.

These agreements include:

(cid:129) a loan agreement for interest-free loan in an aggregate amount of RMB9.0 million to the individual

shareholder of BaiduPay;

(cid:129) a trademark license agreement and a webpage copyright license agreement between BaiduPay and Baidu
Online. After the transfer of a pending trademark application from Baidu Online to BaiduPay is completed,
the trademark license agreement will be terminated. We do not expect the termination of this agreement to
have any material effect on our operations.

The terms of these contractual arrangements are similar to the terms of our contractual arrangements with

Baidu Netcom and its shareholders.

Transaction with UiTV

In September 2008, we entered into agreements with UiTV, operator of an Internet television platform in
China. Under these agreements, we will contribute assets related to the operation of Baidu Internet TV Channel to
UiTV in exchange for an 8.3% stake in UiTV and US$15 million. James Ding, one of our independent directors, is
the chairman of UiTV and owns approximately 17.6% of the equity interests in UiTV. This transaction has not been
closed as of the date of this annual report, pending completion of transfer of certain intellectual property rights.

Item 8. FINANCIAL INFORMATION

A. Consolidated Statements and Other Financial Information

We have appended consolidated financial statements filed as part of this annual report.

Legal Proceedings

From time to time, we have been involved in litigation or other disputes regarding, among other things,
copyright and trademark infringement, defamation, unfair competition and labor disputes. Our search results
provide links to materials, and our Baidu Post Bar, Baidu Knows, Baidu Space and other Baidu communities may
contain materials, in which others may allege to own copyrights, trademarks or image rights or which others may
claim to be defamatory or objectionable. We have received notice letters from third parties asserting copyright
infringement, unfair competition, defamation, breach of contract and labor-related claims against us.

As of March 31, 2009, we were involved in 29 cases pending in various PRC courts, including the cases
summarized below. The aggregate amount of compensation sought under these cases is approximately RMB73 mil-
lion (US$10.7 million).

In March 2008, we received complaints filed by three record companies and the Music Copyright Society of
China against us, alleging, among other things, that we have aided illegal online copying of music or song lyrics by
providing links to pirated music or song lyrics. We expect that the Protection of the Right of Communication
through Information Network, which was promulgated by the State Council and became effective on July 1, 2006,
will be applied to these cases. Because these cases are still pending, we cannot predict their outcomes. See
“Item 3D. Key Information — Risk Factors — Risks Related to Our Business — We may face intellectual property
infringement claims and other related claims that could be time-consuming and costly to defend and may result in
our inability to continue providing certain of our existing services.”

In January 2009, we received a complaint filed by a medical company alleging that Baidu abused its dominant
market position by screening out the website of the medical company. Because the case is still at an early stage and
there has been no ruling on such cases by PRC courts since the promulgation of the new Anti-Monopoly Law, we
cannot predict its outcome.

Although we cannot predict with certainty the results of pending litigation and claims, we believe that the final
outcome of pending litigation and claims will not have a material adverse effect on our business and results of
operations. Regardless of the outcome, however, any litigation can result in substantial costs and diversion of
management resources and attention.

Dividend Policy

We have never declared or paid any dividends, nor do we have any present plan to pay any cash dividends on
our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and
any future earnings to operate and expand our business.

Our board of directors has complete discretion whether to distribute dividends. Even if our board of directors
decides to pay dividends, the form, frequency and amount of our dividends will depend upon our future operations
and earnings, capital requirements and surplus, financial condition, contractual restrictions and other factors that
our board of directors may deem relevant. If we pay any dividends, we will pay our ADS holders to the same extent
as holders of our ordinary shares, subject to the terms of the deposit agreement, including the fees and expenses
payable thereunder. Cash dividends on our ordinary shares, if any, will be paid in U.S. dollars.

B. Memorandum and Articles of Association

The following are summaries of material provisions of our third amended and restated memorandum and
articles of association, as well as the Companies Law (2007 Revision) insofar as they relate to the material terms of
our ordinary shares.

Registered Office and Objects

The Registered Office of our company is at the offices of Maples Corporate Services Limited, PO Box 309,
Ugland House, Grand Cayman, KY1-1104, Cayman Islands or at such other place as our board of directors may
from time to time decide. The objects for which our company is established are unrestricted and we have full power
and authority to carry out any object not prohibited by the Companies Law (2007 Revision), as amended from time
to time, or any other law of the Cayman Islands.

Board of Directors

See “Item 6.C. Board Practices — Board of Directors.”

Ordinary Shares

General. Our ordinary shares are divided into Class A ordinary shares and Class B ordinary shares. Holders
of Class A ordinary shares and Class B ordinary shares have the same rights except for voting and conversion rights.
All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary
shares are issued in registered form. Our shareholders who are nonresidents of the Cayman Islands may freely hold
and vote their shares.

Dividends. The holders of our ordinary shares are entitled to such dividends as may be declared by our board

of directors subject to the Companies Law.

Conversion. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the
holder thereof. Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances.
Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity which is not an affiliate of
such holder (as defined in our articles of incorporation), such Class B ordinary shares shall be automatically and
immediately converted into the equal number of Class A ordinary shares. In addition, if at any time our chairman
and chief executive officer, Robin Yanhong Li, and his affiliates collectively own less than 5% of the total number of
the issued and outstanding Class B ordinary shares, each issued and outstanding Class B ordinary share shall be
automatically and immediately converted into one share of Class A ordinary share, and we shall not issue any
Class B ordinary shares thereafter.

Voting Rights. All of our shareholders have the right to receive notice of shareholders’ meetings and to
attend, speak and vote at such meetings. In respect of matters requiring shareholders’ vote, each Class A ordinary

88

NEXT PCN: 090.00.00.00 -- Page is valid, no graphics

BOM  H03242  089.00.00.00  11

share is entitled to one vote, and each Class B ordinary share is entitled to 10 votes. A shareholder may participate at
a shareholders’ meeting in person, by proxy or by telephone conference or other communications equipment by
means of which all the shareholders participating in the meeting can communicate with each other. At any
shareholders’ meeting, a resolution put to the vote of the meeting shall be decided on a poll conducted by the
chairman of the meeting.

A quorum for a shareholders’ meeting consists of one or more shareholders holding at least one third of the
paid up voting share capital present in person or by proxy or, if a corporation or other non-natural person, by its duly
authorized representative. We shall, if required by the Companies Law, hold a general meeting of shareholders as
our annual general meeting and shall specify the meeting as such in the notices calling it. Our board of directors may
call extraordinary general meetings, and they must on shareholders’ requisition convene an extraordinary general
meeting. A shareholder requisition is a requisition of shareholders holding at the date of deposit of the requisition
not less than a majority of the voting power represented by the issued shares of our company as at that date carries
the right of voting at general meetings of our company. Advance notice of at least five days is required for the
convening of our annual general meeting and other shareholders’ meetings.

An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the
votes attaching to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative
vote of no less than two-thirds of the votes cast attaching to the ordinary shares cast in a general meeting. A special
resolution is required for matters such as a change of name. Holders of the ordinary shares may effect certain
changes by ordinary resolution, including consolidating and dividing all or any of our share capital into shares of
larger amount than our existing share capital and canceling any shares.

Transfer of Shares. Subject to the restrictions of our memorandum and articles of association, as applicable,
any of our shareholders may transfer any or all of his or her ordinary shares by an instrument of transfer in the usual
or common form or any other form approved by our board of directors.

Our board of directors may, in their absolute discretion (except with respect to a transfer from a shareholder to
its affiliate(s)), decline to register any transfer of shares without assigning any reason therefor. If our board of
directors refuses to register a transfer they shall notify the transferee within two months of such refusal.
Notwithstanding the foregoing, if a transfer complies with the holder’s transfer obligations and restrictions set
forth under applicable law (including but not limited to U.S. securities law provisions related to insider trading) and
our articles of association, our board of directors shall promptly register such transfer. Further, any director is
authorized to confirm in writing addressed to the registered office to authorize a share transfer and to instruct that
the register of members be updated accordingly, provided that the transfer complies with the holder’s transfer
obligations and restrictions set forth under applicable law and our articles of association and such holder is not the
director who authorizes the transfer or an entity affiliated with such director. Any director is authorized to execute a
share certificate in respect of such shares for and on behalf of our company.

The registration of transfers may be suspended at such time and for such periods as our board of directors may
from time to time determine, provided, however, that the registration of transfers shall not be suspended for more
than 45 days in any year.

Liquidation. On a return of capital on winding up or otherwise (other than on conversion, redemption or
purchase of shares), assets available for distribution among the holders of ordinary shares may be distributed among
the holders of the ordinary shares as determined by the liquidator, subject to sanction of a special resolution of our
company. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be
distributed so that the losses are borne by our shareholders proportionately to the capital paid up, or which ought to
have been paid up, at the commencement of the winding up on the shares held by such shareholders respectively.

Calls on Shares and Forfeiture of Shares. Our board of directors may from time to time make calls upon
shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to
the specified time and place of payment. The shares that have been called upon and remain unpaid on the specified
time are subject to forfeiture.

BOM  H03242  090.00.00.00  11

Redemption of Shares. Subject to the provisions of the Companies Law and our articles of association, we
may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms
and in such manner as our board of directors may determine.

Repurchase of Shares. Subject to the provisions of the Companies Law and our articles of association, our
board of directors may authorize repurchase of our shares in accordance with the manner of purchase specified in
our articles of association without seeking shareholder approval.

Variations of Rights of Shares. All or any of the special rights attached to any class of shares may, subject to
the provisions of the Companies Law, be varied either with the written consent of the holders of a majority of the
issued shares of that class or with the sanction of a special resolution passed at a general meeting of the holders of
the shares of that class.

Inspection of Books and Records. No holders of our ordinary shares who is not a director shall have any right
of inspecting any of our accounts, books or documents except as conferred by the Companies Law or authorized by
the directors or by us in general meeting. However, we will make this annual report, which contains our audited
financial statements, available to shareholders and ADS holders. See “Item 10.H. Documents on Display.”

Preferred Shares

Our board of directors have the authority, without shareholder approval,

to issue up to a total of
10,000,000 shares of preferred shares in one or more series. Our board of directors may establish the number
of shares to be included in each such series and may set the designations, preferences, powers and other rights of the
shares of a series of preferred shares. While the issuance of preferred shares provides us with flexibility in
connection with possible acquisitions or other corporate purposes, it could, among other things, have the effect of
delaying, deferring or preventing a change of control transaction and could adversely affect the market price of our
ADSs. We have no current plan to issue any preferred shares.

C. Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than

those described in “Item 4. Information on the Company” or elsewhere in this annual report on Form 20-F.

D. Exchange Controls

See “Item 4.B. Information on the Company — Business Overview — Regulation — Regulations on Foreign

Exchange.”

E. Taxation

The following summary of the material Cayman Islands and United States federal income tax consequences of
an investment in our ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of
the date of this annual report, all of which are subject to change. This summary does not deal with all possible tax
consequences relating to an investment in our ADSs or ordinary shares, such as the tax consequences under state,
local and other tax laws.

Cayman Islands Taxation

According to Maples and Calder, our Cayman Islands counsel, the Cayman Islands currently levies no taxes on
individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of
inheritance tax or estate duty. There are no other taxes likely to be material to us levied by the Government of the
Cayman Islands except for stamp duties which may be applicable on instruments executed in, or brought within, the
jurisdiction of the Cayman Islands. The Cayman Islands is not party to any double tax treaties. There are no
exchange control regulations or currency restrictions in the Cayman Islands.

United States Federal Income Taxation

The following discussion describes the material United States federal income tax consequences to U.S. Holders
(defined below) under present law of an investment in the ADSs or ordinary shares. This summary applies only to
investors that hold the ADSs or ordinary shares as capital assets and that have the U.S. dollar as their functional
currency. This discussion is based on the tax laws of the United States as in effect on the date of this Form 20-F and
on United States Treasury regulations in effect or, in some cases, proposed, as of the date of this Form 20-F, as well
as judicial and administrative interpretations thereof available on or before such date. All of the foregoing
authorities are subject to change, which change could apply retroactively and could affect the tax consequences
described below.

The following discussion does not deal with the tax consequences to any particular investor or to persons in

special tax situations such as:

(cid:129) banks;

(cid:129) financial institutions;

(cid:129) insurance companies;

(cid:129) broker dealers;

(cid:129) traders that elect to mark to market;

(cid:129) tax-exempt entities;

(cid:129) persons liable for alternative minimum tax;

(cid:129) persons holding an ADS or ordinary share as part of a straddle, hedging, conversion or integrated

transaction;

(cid:129) persons that actually or constructively own 10% or more of our voting shares;

(cid:129) persons holding ADSs or ordinary shares through partnerships or other pass-through entities; or

(cid:129) persons who acquired ADSs or ordinary shares pursuant to the exercise of any employee share option or

otherwise as consideration.

U.S. Holders are urged to consult their tax advisors about the application of the United States federal tax
rules to their particular circumstances as well as the state and local and foreign tax consequences to them of
the purchase, ownership and disposition of ADSs or ordinary shares.

The discussion below of the United States federal income tax consequences to “U.S. Holders” will apply if you
are the beneficial owner of ADSs or ordinary shares and you are, for United States federal income tax purposes,

(cid:129) a citizen or individual resident of the United States;

(cid:129) a corporation (or other entity taxable as a corporation for United States federal income tax purposes)

organized under the laws of the United States, any State or the District of Columbia;

(cid:129) an estate whose income is subject to United States federal income taxation regardless of its source; or

(cid:129) a trust that (1) is subject to the supervision of a court within the United States and the control of one or more
United States persons or (2) has a valid election in effect under applicable United States Treasury regulations
to be treated as a United States person.

The discussion below assumes that the representations contained in the deposit agreement are true and that the
obligations in the deposit agreement and any related agreement will be complied with in accordance with their
terms. If you hold ADSs, you will be treated as the holder of the underlying ordinary shares represented by those
ADSs for United States federal income tax purposes.

The U.S. Treasury has expressed concerns that parties to whom ADSs are pre-released may be taking actions
that are inconsistent with the claiming, by U.S. Holders of ADSs, of foreign tax credits for United States federal

91

ACEBOWNE OF MONTREAL, INC

04/09/2009 07:28 NO MARKS 

NEXT PCN: 093.00.00.00 -- Page is valid, no graphics

BOM  H03242  092.00.00.00  10

income tax purposes. Such actions would also be inconsistent with the claiming of the reduced rate of tax applicable
to dividends received by certain non-corporate U.S. Holders, as described below. Accordingly, the availability of the
reduced tax rate for dividends received by certain non-corporate U.S. Holders could be affected by future actions
that may be taken by the U.S. Treasury or parties to whom ADSs are pre-released.

Taxation of Dividends and Other Distributions on the ADSs or Ordinary Shares

Subject to the passive foreign investment company rules discussed below, the gross amount of all our
distributions to you with respect to the ADSs or ordinary shares will be included in your gross income as dividend
income on the date of receipt by the depositary, in the case of ADSs, or by you, in the case of ordinary shares, but
only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed
under United States federal income tax principles). The dividends will not be eligible for the dividends-received
deduction allowed to corporations in respect of dividends received from other U.S. corporations.

With respect to non-corporate U.S. Holders (including individual U.S. Holders) for taxable years beginning
before January 1, 2011, dividends may be taxed at the lower applicable capital gains rate (“qualified dividend
income”) provided that (1) the ADSs or ordinary shares are readily tradable on an established securities market in
the United States or we are eligible for the benefit of the income tax treaty between the United States and the PRC,
(2) we are not a passive foreign investment company (as discussed below) for either our taxable year in which the
dividend was paid or the preceding taxable year, and (3) certain holding period requirements are met. For this
purpose, ADSs listed on the Nasdaq National Market will be considered to be readily tradable on an established
securities market in the United States. You should consult your tax advisor regarding the availability of the lower
rate for dividends paid with respect to our ADSs or ordinary shares.

Dividends will constitute foreign source income for foreign tax credit limitation purposes. If the dividends are
qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of
calculating the foreign tax credit limitation will be limited to the gross amount of the dividend, multiplied by the
reduced rate divided by the highest rate of tax normally applicable to dividends. The limitation on foreign taxes
eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends
distributed by us with respect to ADSs or ordinary shares generally will constitute “passive category income” but
could, in the case of certain U.S. Holders, constitute “general category income.” If PRC withholding taxes apply to
dividends paid to you with respect to the ADSs or ordinary shares, you may be able to obtain a reduced rate of PRC
withholding taxes under the income tax treaty between the United States and the PRC if certain requirements are
met. In addition, subject to certain conditions and limitations, PRC withholding taxes on dividends may be treated
as foreign taxes eligible for credit against your U.S. federal income tax liability. U.S. Holders should consult their
own tax advisors regarding the creditability of any PRC tax.

To the extent that the amount of the distribution exceeds our current and accumulated earnings and profits, it
will be treated first as a tax-free return of your tax basis in your ADSs or ordinary shares, and to the extent the
amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain. We do not intend to
calculate our earnings and profits for United States federal income tax purposes. Therefore, a U.S. Holder should
expect that a distribution will be reported as a dividend.

Taxation of Disposition of Shares

Subject to the passive foreign investment company rules discussed below, you will recognize taxable gain or
loss on any sale, exchange or other taxable disposition of an ADS or ordinary share equal to the difference between
the amount realized (in U.S. dollars) for the ADS or ordinary share and your tax basis (in U.S. dollars) in the ADS or
ordinary share. The gain or loss will be capital gain or loss. If you are a non-corporate U.S. Holder, including an
individual U.S. Holder, who has held the ADS or ordinary share for more than one year, you will be eligible for
reduced tax rates. The deductibility of capital losses is subject to limitations. Any such gain or loss that you
recognize generally will be treated as United States source income or loss (in the case of losses, subject to certain
limitations). However, in the event we are deemed to be a Chinese “resident enterprise” under PRC tax law, we may
be eligible for the benefits of the income tax treaty between the United States and the PRC. In such event, if PRC tax
were to be imposed on any gain from the disposition of the ADSs or ordinary shares, a U.S. Holder that is eligible for

92

NEXT PCN: 094.00.00.00 -- Page is valid, no graphics

BOM  H03242  093.00.00.00  10

the benefits of the income tax treaty between the United States and the PRC may elect to treat such gain as PRC
source income. U.S. Holders should consult their own tax advisors regarding the creditability of any PRC tax.

Passive Foreign Investment Company

Based on the market value of our ADSs and ordinary shares, the composition of our assets and income and our
operations, we believe that for our taxable year ended December 31, 2008, we were not a passive foreign investment
company (“PFIC”) for United States federal income tax purposes. However, our PFIC status for the current taxable
year ending December 31, 2009 will not be determinable until its close, and, accordingly, there is no guarantee that
we will not be a PFIC for the current taxable year (or any future taxable year). A non-U.S. corporation is considered
a PFIC for any taxable year if either:

(cid:129) at least 75% of its gross income is passive income (the “income test”), or

(cid:129) at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a
taxable year) is attributable to assets that produce or are held for the production of passive income (the “asset
test”).

We will be treated as owning our proportionate share of the assets and earning our proportionate share of the
income of any other corporation in which we own, directly or indirectly, more than 25% (by value) of the shares.

We must make a separate determination each year as to whether we are a PFIC. As a result, our PFIC status
may change. In particular, because the total value of our assets for purposes of the asset test generally will be
calculated using the market price of our ADSs and ordinary shares, our PFIC status will depend in large part on the
market price of our ADSs and ordinary shares which may fluctuate considerably. Accordingly, fluctuations in the
market price of the ADSs and ordinary shares may result in our being a PFIC for any year. If we are a PFIC for any
year during which you hold ADS or ordinary shares, we will continue to be treated as a PFIC for all succeeding years
during which you hold ADS or ordinary shares. However, if we cease to be a PFIC, provided that you have not made
a mark-to-market election, as described below, you may avoid some of the adverse effects of the PFIC regime by
making a deemed sale election with respect to the ADSs or ordinary shares, as applicable.

If we are a PFIC for any taxable year during which you hold ADSs or ordinary shares, you will be subject to
special tax rules with respect to any “excess distribution” that you receive and any gain you realize from a sale or
other disposition (including a pledge) of the ADSs or ordinary shares, unless you make a “mark-to-market” election
as discussed below. Distributions you receive in a taxable year that are greater than 125% of the average annual
distributions you received during the shorter of the three preceding taxable years or your holding period for the
ADSs or ordinary shares will be treated as an excess distribution. Under these special tax rules:

(cid:129) the excess distribution or gain will be allocated ratably over your holding period for the ADSs or ordinary

shares,

(cid:129) the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which

we became a PFIC, will be treated as ordinary income, and

(cid:129) the amount allocated to each other taxable year will be subject to the highest tax rate in effect for that taxable
year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting
tax attributable to each such taxable year.

The tax liability for amounts allocated to years prior to the year of disposition or “excess distribution” cannot
be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the ADSs or
ordinary shares cannot be treated as capital, even if you hold the ADSs or ordinary shares as capital assets.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) in a PFIC may make a mark-to-market
election for such stock of a PFIC to elect out of the tax treatment discussed in the two preceding paragraphs. If you
make a valid mark-to-market election for the ADSs or ordinary shares, you will include in income each year an
amount equal to the excess, if any, of the fair market value of the ADSs or ordinary shares as of the close of your
taxable year over your adjusted basis in such ADSs or ordinary shares. You are allowed a deduction for the excess, if
any, of the adjusted basis of the ADSs or ordinary shares over their fair market value as of the close of the taxable

93

NEXT PCN: 095.00.00.00 -- Page is valid, no graphics

year. However, deductions are allowable only to the extent of any net mark-to-market gains on the ADSs or ordinary
shares included in your income for prior taxable years. Amounts included in your income under a mark-to-market
election, as well as gain on the actual sale or other disposition of the ADSs or ordinary shares, are treated as ordinary
income. Ordinary loss treatment also applies to the deductible portion of any mark-to-market loss on the ADSs or
ordinary shares, as well as to any loss realized on the actual sale or disposition of the ADSs or ordinary shares, to the
extent that the amount of such loss does not exceed the net mark-to-market gains previously included for such ADSs
or ordinary shares. Your basis in the ADSs or ordinary shares will be adjusted to reflect any such income or loss
amounts. If you make such a mark-to-market election, tax rules that apply to distributions by corporations which are
not PFICs would apply to distributions by us (except that the lower applicable capital gains rate would not apply).

The mark-to-market election is available only for “marketable stock” which is stock that is traded in other than
de minimis quantities on at least 15 days during each calendar quarter (“regularly traded”) on a qualified exchange
or other market, as defined in applicable Treasury regulations. We expect that the ADSs will continue to be listed on
the Nasdaq National Market, which is a qualified exchange for these purposes, and, consequently, assuming that the
ADSs are regularly traded, if you are a holder of ADSs, it is expected that the mark-to-market election would be
available to you were we to become a PFIC.

If you hold ADSs or ordinary shares in any year in which we are a PFIC, you will be required to file Internal
Revenue Service Form 8621 regarding distributions received on the ADSs or ordinary shares and any gain realized
on the disposition of the ADSs or ordinary shares.

You are urged to consult your tax advisor regarding the application of the PFIC rules to your investment in

ADSs or ordinary shares.

Information Reporting and Backup Withholding

Dividend payments with respect to ADSs or ordinary shares and proceeds from the sale, exchange or
redemption of ADSs or ordinary shares may be subject to information reporting to the Internal Revenue Service and
possible United States backup withholding at a current rate of 28%. Backup withholding will not apply, however, to
a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or
who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status
must provide such certification on Internal Revenue Service Form W-9. U.S. Holders should consult their tax
advisors regarding the application of the United States information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against
your United States federal income tax liability, and you may obtain a refund of any excess amounts withheld under
the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service and
furnishing any required information.

Item 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our exposure to interest rate risk primarily relates to excess cash invested in short-term fixed income
instruments with original maturities of less than a year. Investments in both fixed rate and floating rate interest
earning instruments 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 we have to sell securities which
have declined in market value due to changes in interest rates. We have not been, and do not expect to be, exposed to
material interest rate risks, and therefore have not used any derivative financial instruments to manage our interest
risk exposure.

We had RMB301.2 million (US$44.2 million) short-term investments as of December 31, 2008, with a
weighted average duration of approximately 0.29 year. A hypothetical one percentage point (100 basis-point)
increase in interest rates would have resulted in a decrease of approximately RMB0.9 million (US$0.1 million) in
the fair value of our fixed-income investments at December 31, 2008.

Foreign Exchange Risk

Most of our revenues and costs are denominated in RMB, while a significant portion of our cash and cash
equivalents and short-term financial assets are denominated in U.S. dollars and held by the Cayman holding
company. Our exposure to foreign exchange risk primarily relates to those financial assets denominated in
U.S. dollars, mainly as a result of our past issuances of convertible preferred shares through private placements and
proceeds from our initial public offering. In addition, we commenced operation in Japan in late 2007. Until our
Japan operation becomes self-sufficient, we will need to make capital injections into our Japan operation by
converting U.S. dollars into Japanese Yen. We have not hedged exposures denominated in foreign currencies using
any derivative financial instruments. Any significant revaluation of RMB against the U.S. dollar may materially
affect our revenues, earnings and financial position, and the value of, and any dividends payable on, our ADS in

U.S. dollars. See “Item 3D. Key Information — Risk Factors — Risks Related to Doing Business in China —
Fluctuation in the value of the RMB may have a material adverse effect on your investment.”

The RMB appreciated by 6.47% against the U.S. dollar in 2008. A 10% decrease in the exchange rate of the
U.S. dollar against the RMB would have resulted in a decrease of RMB43.6 million (US$6.4 million) in the value of
our U.S. dollar- denominated financial assets at December 31, 2008.

Item 15. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, has
performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e)
under the Exchange Act) as of the end of the period covered by this report, as required by Rule 13a-15(b) under the
Exchange Act.

Based upon that evaluation, our management has concluded that, as of December 31, 2008, our disclosure
controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports
that we file and furnish under the Exchange Act was recorded, processed, summarized and reported, within the time
periods specified in the SEC’s rules and forms, and that the information required to be disclosed by us in the reports
that we file or submit under the Exchange Act is accumulated and communicated to our management, including our
chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as defined in Rule 13a-15(f) under the Exchange Act. Our management evaluated the effectiveness of our
internal control over financial reporting, as required by Rule 13a-15(c) of the Exchange Act, based on criteria
established in the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on this evaluation, our management has concluded that our
internal control over financial reporting was effective as of December 31, 2008.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. In addition, projections of any evaluation of effectiveness of our internal control over financial
reporting 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 and procedures may deteriorate.

Our independent registered public accounting firm, Ernst & Young Hua Ming, has audited the effectiveness of
our internal control over financial reporting as of December 31, 2008, as stated in its report, which appears on
page F-2 of this annual report on Form 20-F.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting that occurred during the period covered
by this annual report on Form 20-F that have materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.

ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT

Our board of directors has determined that Mr. William Decker, an independent director (under the standards
set forth in Nasdaq Marketplace Rule 4350(d) and Rule 10A-3 under the Exchange Act) and member of our audit
committee, is an audit committee financial expert.

ITEM 16B. CODE OF ETHICS

Our board of directors adopted a code of business conduct and ethics that applies to our directors, officers,
employees and advisors in July 2005. We have posted a copy of our code of business conduct and ethics on our
website at http://ir.baidu.com.

ITEM 16C. PRINCIPAL ACCOUNTANT FEES AND SERVICES

2008

(1) “Audit fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered
by our principal auditors for the audit of our annual financial statements. In 2007 and 2008, the audit refers to
integrated audit, including financial audit and audit pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

(2) “Tax fees” means the aggregate fees billed in each of the fiscal years listed for professional services rendered by
our principal auditors for tax compliance, tax advice, and tax planning. In 2008, the tax fees refer to fees paid to
our principal auditors to review the compliance of our tax documentation.

All audit and non-audit services provided by our independent auditors must be pre-approved by our audit
committee. Our audit committee has adopted a combination of two approaches in pre-approving proposed services:
general pre-approval and specific pre-approval. With general approval, proposed services are pre-approved without
consideration of specific case-by-case services; with specific approval, proposed services require the specific pre-
approval of the audit committee. Unless a type of service has received general pre-approval, it will require specific
pre-approval by our audit committee. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by our audit committee.

All requests or applications for services to be provided by our independent auditors that do not require specific
approval by our audit committee will be submitted to our chief financial officer and must include a detailed
description of the services to be rendered. The chief financial officer will determine whether such services are
included within the list of services that have received the general pre-approval of the audit committee. The audit
committee will be informed on a timely basis of any such services. Requests or applications to provide services that
require specific approval by our audit committee will be submitted to the audit committee by both our independent
auditors and our chief financial officer and must include a joint statement as to whether, in their view, the request or
application is consistent with the SEC’s rules on auditor independence.

ITEM 16D. EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES

Not applicable.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS

No equity securities of our company were purchased by or on behalf of our company or any “affiliated
purchaser” (as such term is defined in Rule 10b-18 under the Exchange Act) of our company in the year ended
December 31, 2008. In 2008, we received authorizations and approvals from our board of directors and shareholders
to repurchase up to US$200 million of our ordinary shares represented by ADSs by the end of 2009.

As part of our share repurchase plan, in late December 2008, we entered into a structured share repurchase
transaction with a major financial institution. Under this transaction, we made an upfront cash payment of
US$10 million in exchange for the right to receive either a number of our ADSs or a cash settlement amount (which
is equal to our upfront cash payment plus a pre-determined premium) upon the expiration of the three-month term of
the transaction, depending on the volume weighted average price (VWAP) of our ADSs at such expiration date. On
the settlement date for this transaction in March 2009, we received US$10.84 million in cash, including a pre-
determined premium of US$0.84 million. In March 2009, we entered into a similar transaction with the same
financial institution with an upfront payment of US$20 million.

Furthermore, we commenced repurchase of our ADSs in the open market in the first quarter of 2009 pursuant
to a Rule 10b5-1 share repurchase plan. As of March 31, 2009, we have purchased a total of 32,470 of our ADSs at
an average price of $109.0679 per ADS, including transaction costs. The ordinary shares underlying the repur-
chased ADSs will be canceled in accordance with Cayman Islands law. As of March 31, 2009, approximately
US$196.5 million of our ADSs may still be repurchased by the end of 2009.

ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT

Not applicable.

ITEM 16G. CORPORATE GOVERNANCE

Nasdaq Marketplace Rule 4350(e) requires each issuer to hold an annual meeting of shareholders no later than
one year after the end of the issuer’s fiscal year-end. However, Nasdaq Marketplace Rule 4350(a)(1) permits foreign
private issuers like us to follow “home country practice” in certain corporate governance matters. Maples and
Calder, our Cayman Islands counsel, has provided a letter to the Nasdaq Stock Market certifying that under Cayman
Islands law, we are not required to hold annual shareholder meetings every year.

We may follow home country practice with respect to annual meetings. We held an annual meeting of
shareholders in December 2008 for the purposes of obtaining shareholders’ approvals on certain corporate matters
requiring shareholders’ approvals. We may hold additional annual shareholder meetings in the future if there are
significant issues that require shareholders’ approvals.

Other than the annual meeting requirements, we have followed and intend to continue to follow the applicable

corporate governance standards under Nasdaq Marketplace Rules.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Baidu, Inc.

We have audited the accompanying consolidated balance sheets of Baidu, Inc. (the “Company”) and
subsidiaries as of December 31, 2007 and 2008, and the related consolidated statements of income, shareholders’
equity, and cash flows for each of the three years in the period ended December 31, 2008. 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 Baidu, Inc. and subsidiaries at December 31, 2007 and 2008, and the consolidated
results of their operations and their cash flows for each of the three years in the period ended December 31, 2008, in
conformity with U.S. generally accepted accounting principles.

As discussed in Note 2 to these consolidated financial statements, in 2006, the Company changed its method of
accounting for share-based payments in accordance with the guidance provided in the Statement of Financial
Accounting Standards No. 123(R), Share-Based Payment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Baidu, Inc.’s internal control over financial reporting as of December 31, 2008, based on criteria
established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission and our report dated April 7, 2009 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Baidu, Inc.

We have audited Baidu, Inc.’s internal control over financial reporting as of December 31, 2008, based on
criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Orga-
nizations of the Treadway Commission (the COSO criteria). Baidu, Inc.’s management is responsible for main-
taining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting included in the accompanying Management’s Report on 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,
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, Baidu, Inc. maintained, in all material respects, effective internal control over financial

reporting as of December 31, 2008, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the accompanying consolidated balance sheets of Baidu, Inc. and subsidiaries as of December 31,
2007 and 2008, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of
the three years in the period ended December 31, 2008, and our report dated April 7, 2009, expressed an unqualified
opinion thereon.

BAIDU, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 2006, 2007, and 2008

1. ORGANIZATION AND BASIS OF PRESENTATION

Baidu, Inc. (“Baidu” or the “Company”) was incorporated under the laws of the Cayman Islands on January 18,
2000. The Company was formerly known as Baidu.com, Inc. and changed its name to Baidu, Inc. on December 16,
2008. The Company is the 100% shareholder of Baidu Holdings Ltd. (“Baidu Holdings”) incorporated in the British
Virgin Islands. As of December 31, 2008, Baidu Holdings owned three subsidiaries, details of which are as follows:

(cid:129) Baidu Online Network Technology (Beijing) Co., Ltd. (“Baidu Online”) incorporated under the laws of the

People’s Republic of China (“PRC”) on January 18, 2000,

(cid:129) Baidu, Inc. (“Baidu Japan”) incorporated in Tokyo under the laws of Japan on December 13, 2006, and

(cid:129) Baidu (Hong Kong) Limited (“Baidu HK”) incorporated in Hong Kong under the laws of Hong Kong on

November 27, 2007.

Baidu HK owned two operational subsidiaries in the PRC, details of which are as follows:

(cid:129) Baidu (China) Co., Ltd. (“Baidu China”) incorporated under the laws of the PRC on June 6, 2005, and

(cid:129) Baidu.com Times Technology (Beijing) Co., Ltd. (“Baidu Times”) incorporated under the laws of the PRC

on April 19, 2006.

Baidu Japan established two wholly-owned subsidiaries in Japan, details of which are as follows:

(cid:129) Hyakudo Inc. (“Hyakudo”) incorporated in Tokyo under the laws of Japan on April 14, 2008, and

(cid:129) Baido, Inc. (“Baido”) incorporated in Tokyo under the laws of Japan on April 14, 2008

As of December 31, 2008, the Company also effectively controlled three variable interest entities (“VIEs”):

(cid:129) Beijing Baidu Netcom Science Technology Co., Ltd. (“Baidu Netcom”) incorporated under the laws of the

PRC on June 5, 2001,

(cid:129) Beijing Perusal Technology Co., Ltd. (“Beijing Perusal”) incorporated under the laws of the PRC on June 6,

2006, and

(cid:129) Beijing BaiduPay Science and Technology Co., Ltd. (“BaiduPay”) incorporated under the laws of the PRC

on February 27, 2008.

The Company, its subsidiaries and VIEs are hereinafter collectively referred to as the “Group.” The Group
offers Internet search solutions and online marketing solutions, operates an e-commerce platform with an online
payment tool which enables e-commerce merchants and customers to make payments online, develops and markets
scaleable web application software and provides related services. The Group’s principal geographic market is in the
PRC and Japan. The Company does not conduct any substantive operations of its own and conducts its primary
business operations through its wholly-owned subsidiaries and VIEs in the PRC and Japan.

PRC laws and regulations prohibit or restrict foreign ownership of Internet content and advertising businesses.
To comply with these foreign ownership restrictions, the Group operates its websites and provides online
advertising services in the PRC through VIEs, the PRC legal entities that were established by the individuals
authorized by the Group. The paid-in capital of the VIEs was funded by the Group through loans extended to the
authorized individuals. The Group has entered into certain exclusive agreements with the VIEs through Baidu
Online, which obligate Baidu Online to absorb a majority of the risk of loss from the VIEs’ activities and entitles
Baidu Online to receive a majority of their residual returns. In addition, the Group has entered into certain
agreements with the authorized individuals through Baidu Online, including loan agreements for the paid-in capital
of the VIEs, option agreements to acquire the equity interests in the VIEs when permitted by the PRC laws, and
share pledge agreements for the equity interests in the VIEs held by the authorized individuals.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

Based on these contractual arrangements, the Company consolidates the VIEs as required by Financial
Accounting Standards Board (“FASB”) Interpretation No. 46R (“FIN 46R”), Consolidation of Variable Interest
Entities, an Interpretation of ARB No. 51 because the Company holds all the variable interests of VIEs through
Baidu Online, which is the primary beneficiary of the VIEs. Despite the lack of technical majority ownership, there
exists a parent-subsidiary relationship between the Company and VIEs through the aforementioned agreements,
whereby the equity holders of VIEs effectively assigned all of their voting rights underlying their equity interest in
VIEs to Baidu Online. In addition, through the other aforementioned agreements, the Company demonstrates its
ability and intention to continue to exercise the ability to absorb substantially all of the profits and all of the expected
losses of VIEs.

The carrying amount of the total assets of VIEs as of December 31, 2008 was RMB377.05 million
(US$55.27 million) and there was no pledge or collateralization of their assets. The amount of the net assets
of VIEs as of December 31, 2008 was RMB217.60 million (US$31.89 million).

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements were prepared in accordance with United States generally accepted
accounting principles (“U.S. GAAP”). The consolidated financial statements include the financial statements of the
Company, its subsidiaries and VIEs in which the Company holds all the variable interests of VIEs through Baidu
Online. All inter-company transactions and balances between the Company, its subsidiaries and VIEs are
eliminated upon consolidation. The Company has included the results of operations of acquired businesses from
the respective date of acquisition.

Currency Translation for Financial Statements Presentation

Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the exchange
rate of RMB6.8225 per US$1.00 on December 31, 2008 as published on the website of the Federal Reserve Bank of
New York. No representation is made that the RMB amounts could have been, or could be, converted into
U.S. dollars at such rate.

Foreign Currency

The Company’s functional currency is the US$. The Company’s subsidiaries and VIEs determine their
functional currencies based on the criteria of Statement of Financial Accounting Standards (“SFAS”) 52, Foreign
Currency Translation, and have determined their functional currencies to be their respective local currency. The
Company uses the RMB as its reporting currency. The Company uses the average exchange rate for the year and the
exchange rate at the balance sheet date to translate its operating results and financial position respectively. Any
translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of
shareholders’ equity. We recorded RMB28.2 million, RMB48.3 million and RMB27.6 (US$4.0) million of net
foreign currency translation loss for the years ended December 31, 2006, 2007 and 2008, respectively. Transactions
denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing on the
transaction dates. Assets and liabilities denominated in foreign currencies are translated into the functional currency
at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in the consolidated
statements of income as a component of other income.

Guarantees

The Company accounts for guarantees in accordance with FASB Interpretation No. 45 (“FIN 45”), Guar-
antor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees to Others, an
interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34. Accordingly,

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

the Company evaluates its guarantees to determine whether (a) the guarantee is specifically excluded from the scope
of FIN 45, (b) the guarantee is subject to FIN 45 disclosure requirements only, but not subject to the initial
recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements
at fair value.

The corporate by-laws require that the Company indemnify its officers and directors, as well as those who act
as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services
to the Company. In addition, the Company has entered into separate indemnification agreements with each director
and each executive officer of the Company that provide for indemnification of these directors and officers under
similar circumstances and under additional circumstances. The indemnification obligations are more fully
described in the by-laws and the indemnification agreements. The Company purchases standard directors and
officers insurance to cover claims or a portion of the claims made against its directors and officers. Since a
maximum obligation is not explicitly stated in the Company’s by-laws or in the indemnification agreements and
will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the
obligations cannot be reasonably estimated. Historically, the Company has not been required to make payments
related to these obligations, and the fair value for these obligations is zero in the consolidated balance sheet as of
December 31, 2007 and 2008.

The Company has no other guarantees for any of the years presented.

Use of Estimates

The preparation of 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 disclosures of contingent assets and liabilities at the date of the financial statements and the
reported amounts of revenues and expenses during the period. Management evaluates estimates, including those
related to the accounts receivable allowances, fair values of options to purchase the Company’s ordinary shares, and
deferred tax valuation allowance, among others. Management bases the estimates on historical experience and on
various other assumptions that are believed to be reasonable, the results of which form the basis for making
judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.

Fair Value Measurements

The carrying amounts of the financial instruments, including cash and cash equivalents, short-term invest-
ments, accounts receivable, accounts payable and accrued liabilities, approximate fair value because of their
generally short maturities.

Cash, Cash Equivalents and Short-Term Investments

Cash and cash equivalents are stated at cost, which approximates fair value, and primarily consist of cash and
investments in interest bearing demand deposit accounts, highly liquid investments and money market funds. All
highly liquid investments with stated maturities of three months or less from the date of purchase are classified as
cash equivalents; all highly liquid investments with stated maturities of greater than three months, but less than
12 months, are classified as short-term investments which are stated at their approximate fair value. In 2008, the
Company introduced an e-commerce platform and an online payment platform which enables e-commerce
merchants and customers to send and receive payments online. Cash balances deposited by the customers of
the Company’s e-commerce platform are included as cash and cash equivalents on the consolidated balance sheets.
The cash deposits of such nature are considered restricted because they cannot be used for the operations of the
Group or any other purpose not designated by customers. When customers fund their account in the e-commerce
platform using their bank accounts, the deposited balance is included in the Company’s bank account until
customers either use the cash to settle their online transactions or withdraw the cash. As of December 31, 2008,

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

RMB4.56 (US$0.7) million in the Company’s cash and cash equivalents balance was related to the deposits made by
customers and designated for settlement of their online transactions on the e-commerce platform. There was no cash
balance relating to the e-commerce customer deposits as of December 31, 2007.

The Company accounts for short-term investments in accordance with SFAS No. 115, Accounting for Certain
Investments in Debt and Equity Securities. The Company classifies the short-term investments in debt and equity
securities as “held-to-maturity”, “trading” or “available-for-sale”, whose classification determines the respective
accounting methods stipulated by the accounting standard for financial instruments. The securities that are bought
and held principally for the purpose of selling them in the near term are classified as trading securities. The
securities that the Company has positive intent and ability to hold to maturity are classified as held-to-maturity
securities and stated at amortized cost. The Company does not have available-for-sale securities. Unrealized
holding gains and losses for trading securities are included in earnings. Dividend and interest income, including
amortization of the premium and discount arising at acquisition, for all categories of investments in securities are
included in earnings. Any realized gains or losses on the sale of the short term investments are determined on a
specific identification method, and such gains and losses are reflected in the consolidated statements of income as a
component of interest income.

For individual securities classified as held-to-maturity securities, the Company evaluates whether a decline in
fair value below the amortized cost basis is other than temporary in accordance with our policy and FASB Staff
Position (FSP) No. SFAS 115-1/SFAS 124-1, The Meaning of Other-Than-Temporary Impairment and Its Appli-
cation to Certain Investments. If the decline in fair value is judged to be other than temporary, the cost basis of the
individual security will be written down to fair value as a new cost basis and the amount of the write-down is
included in the consolidated statements of income.

Long-term Investments

The investments in which the Company does not have the ability to exercise significant influence (generally,
when the Company has an investment of less than 20% ownership and no representation on the investee’s board of
directors) and for which there is not a readily determinable fair value, are accounted for using the cost method.
Dividends and other distributions of earnings from investees, if any, are included in income when declared. These
investments are subject to a periodic impairment review whenever circumstances indicate the carrying value of the
long-term investment may not be recoverable. To the extent any impairment is considered other-than-temporary, the
impairment loss measured as the difference between the carrying value and the fair value of the impaired asset is
recorded in the consolidated statements of income. The impairment charge was RMB1.95 million, nil and
RMB7.99 million (US$1.17 million) for the years ended December 31, 2006, 2007 and 2008, respectively.

Capitalization of Software Developed for Internal Use

The Company has capitalized certain internal use software development costs in accordance with Statement of
Position (“SOP”) 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use,
amounting to RMB1.40 million, RMB6.49 million and RMB19.49 million (US$2.86 million) for the years ended
December 31, 2006, 2007 and 2008, respectively. The Company capitalizes certain costs relating to software
acquired, developed, or modified solely to meet the Company’s internal requirements and for which there are no
substantive plans to market the software. These costs mainly included payroll and payroll-related costs for
employees who are directly associated with and who devote time to the internal use software projects during the
application development stage. The estimated useful life of software development costs is determined to be three
years. The amortization expense for capitalized costs amounted to RMB1.66 million, RMB1.26 million and
RMB3.44 million (US$0.50 million) for the years ended December 31, 2006, 2007 and 2008, respectively.
Capitalized internal use software costs are included in fixed assets, net.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation or amortization is recorded on a
straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as follows:

over the shorter of lease terms
or estimated useful lives of the
assets

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments
that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and
disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated
depreciation accounts with any resulting gain or loss reflected in the consolidated statements of income.

All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are
ready for their intended use are capitalized as construction in progress. Construction in progress is transferred to
specific fixed assets items and depreciation of these assets commences when ready for their intended use.

Intangible Assets

Intangible assets are carried at cost less accumulated amortization. Intangible assets, except the land use right,
with a finite useful life, are amortized using the straight-line method over the estimated economic life. The land use
right is amortized using a straight-line method over the shorter of the estimated economic life or the term of related
land use right contract. As of December 31, 2008, intangible assets have weighted average useful lives from the date
of purchase as follows:

Domain name . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Intangible assets with an indefinite useful life are not amortized. One of the Domain Name assets acquired in
July 2006 is not subject to amortization, as the remaining useful life is indefinite. The total amount assigned to this
domain name is RMB9.36 million (US$1.37 million) as of December 31, 2008. In addition, in March 2008, the
Company’s trademark of “BAIDU” was qualified as a China well-known trademark by the State Trademark Office.
The registration costs totaled to RMB1.05 million (US$0.15 million) as of December 31, 2008 is recorded as an
intangible asset not subject to amortization, as the remaining useful life is indefinite. If the intangible assets that are
not being amortized are subsequently determined to have a finite useful life, the assets will be tested for impairment
and then amortized prospectively over its estimated remaining useful life and accounted for in the same manner as
other intangible assets that are subject to amortization. Intangible assets with indefinite useful lives are tested for
impairment annually or more frequently if events or changes in circumstances indicate that they might be impaired.

Impairment of Long-Lived Assets

The Company evaluates long-lived assets, such as fixed assets and purchased or internally developed
intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the
carrying value of an asset may not be recoverable in accordance with SFAS No. 144, Accounting for the Impairment

or Disposal of Long-Lived Assets. When such events occur, the Company assesses the recoverability of the assets
group based on the undiscounted future cash flow the assets group is expected to generate and recognizes an
impairment loss when estimated undiscounted future cash flow expected to result from the use of the assets group
plus net proceeds expected from disposition of the assets group, if any, is less than the carrying value of the assets
group. If the Company identifies an impairment, the Company reduces the carrying amount of the assets group to its
estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable
market values. The Company uses estimates and judgments in its impairment tests and if different estimates or
judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to
be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and 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 balance sheet. There has been no impairment charges of the
Company’s long-lived assets in any of the years presented.

Accounting for Impairment of Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired in
a business combination. The Company assesses goodwill for impairment in accordance with SFAS No. 142
(“SFAS 142”), Goodwill and Other Intangible Assets, which requires that goodwill be tested for impairment at the
reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by
SFAS 142. Consistent with the management’s operational perspective, the Company has determined that it has only
one reporting unit. Goodwill was tested for impairment in the annual impairment tests on December 31 in each year
using the two-step process required by SFAS 142. First, the Company reviewed the carrying amount of the reporting
unit compared to the “fair value” of the Reporting Unit based on quoted market prices of the ordinary shares. If such
comparison reflected potential impairment, the Company would then prepare the discounted cash flow analyses.
Such analyses are based on cash flow assumptions that are consistent with the plans and estimates being used to
manage the business. An excess carrying value compared to fair value would indicate that goodwill may be
impaired. Finally, if the Company determined that goodwill may be impaired, the implied fair value of the goodwill,
as defined by SFAS 142, would be compared to its carrying amount to determine the impairment loss, if any. There
has been no impairment of goodwill in any of the years presented.

Accounts Receivable and Other Receivables

Accounts receivable are recognized and carried at original invoiced amount less an allowance for any potential
uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer
probable. Bad debts are written off as incurred. The Company generally does not require collateral from its
customers.

The Company maintains allowances for doubtful accounts for estimated losses resulting from the failure of
customers to make payments on time. The Company reviews the accounts receivable on a periodic basis and makes
general and specific allowances when there is doubt as to the collectibility of individual balances. In evaluating the
collectibility of individual receivable balances, the Company considers many factors, including the age of the
balance, the customer’s historical payment history, its current credit-worthiness and current economic trends.

Deferred Income

Deferred income represents government subsidies relating to purchased domestic equipment. Deferred income
is amortized over the estimated remaining useful lives of the related fixed assets and credited as other income in the
consolidated statements of income.

BAIDU, INC.

Revenue Recognition

The Company recognizes revenue based on the following principles:

Online marketing services

(1) Auction-based pay-for-performance service

The Company’s auction-based pay-for-performance (“P4P”) platform enables a customer to place its website
link and related description on the Company’s search result list. The customers make bids to determine how much
they are willing to pay for each click to their listings in the search results listed on the Company’s website. The
amount of the customer’s bid will influence the ranking of the customer’s listing in the search results. The customer
pays the Company only when a user clicks on one of its website links. Revenue is generally recognized when a user
clicks on one of the customer-sponsored website links, as there is persuasive evidence of an arrangement, the fee is
fixed or determinable and collection is reasonably assured, as prescribed by Securities and Exchange Committee
(“SEC”) Staff Accounting Bulletin (“SAB”) No. 104 (“SAB 104”).

For certain P4P customers engaged through direct sales, the Company may provide certain value-added
consulting support services to help its customers to better utilize its P4P online marketing system. Fees for such
services are generally recognized as revenue on a pro-rata basis over the contracted service period.

(2) Other performance-based online marketing services

To the extent the Company provides online marketing services based on performance criteria other than click-
throughs, such as the number of telephone calls brought to its customers, the number of users registered with its
customers, or the number of minimum click-throughs, revenue is recognized when the specified performance
criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by SAB 104.

(3) Time-based online advertising services

For time-based online advertising services such as text links, banners, or other forms of graphical adver-
tisements, the Company recognizes revenue, in accordance with SAB 104, on a pro-rata basis over the contractual
term commencing on the date the customer’s advertisement is displayed in a specified webpage. For certain time-
based contractual agreements, the Company may also provide certain performance guarantees, in which cases
revenue is recognized at the later of the completion of the time commitment or performance guarantee.

(4) Online marketing services involving Baidu Union

Baidu Union is the program through which the Company expands distribution of its customers’ sponsored links
or advertisements by leveraging traffic of the Baidu Union members’ internet properties. The Company makes
payments to Baidu Union members for acquisition of traffic. The Company recognizes gross revenue for the amount
of fees it receives from its customers. Payments made to Baidu Union members are included in cost of revenues as
traffic acquisition costs.

(5) Barter transactions

The Company engages in barter transactions occasionally and in such situation follows the provisions of
Accounting Principles Board (“APB”) No. 29, Accounting for Nonmonetary Transactions. While nonmonetary
transactions are generally recorded at fair value, if such value is not determinable within reasonable limits, the
transaction is recognized based on the carrying value of the product or services provided. The amount of revenues
recognized for barter transactions was insignificant for each of the periods presented.

The Company recognizes revenues for barter transactions involving advertising in accordance with Emerging
Issues Task Force (“EITF”) Issue No. 99-17, Accounting for Advertising Barter Transactions. However, neither the

BAIDU, INC.

amount recognized nor the volume of such transactions qualified for income recognition was material for any of the
periods presented.

According to EITF Issue No. 00-8, Accounting by a Grantee for an Equity Instrument to Be Received in
Conjunction with Providing Goods or Services, if the Company provides services in exchange for equity
instruments, the Company is required to measure the fair value of those equity instruments for revenue recognition
purposes as of the earlier of either of the following dates:

(cid:129) The date the parties come to a mutual understanding of the terms of the equity-based compensation
arrangement and a commitment for performance by the Company to earn the equity instruments is reached;

(cid:129) The date at which the Company’s performance necessary to earn the equity instruments is completed.

If, as of the measurement date, the fair value of the equity instruments received is not determinable within
reasonable limits, the transaction is recognized based on the fair value of the services provided. If the fair value of
both the equity instruments received and the services provided cannot be determined, no revenue is recognized for
the services provided and the equity instrument received is recorded at zero carrying value. The amount of revenues
recognized for such transactions was not material for any of the years presented.

(6) Other revenue recognition related policies

If a sales contract stipulates more than one of the services described in (1), (2) and (3) above (collectively the
“Services”), and the Services are considered as multiple accounting units in accordance with EITF Issue No. 00-21,
Revenue Arrangements with Multiple Deliverables, the total revenue on such arrangements is allocated to the
individual deliverables based on their relative fair values. If sufficient vendor-specific objective evidence of fair
value does not exist for the allocation of revenue, the fee for the entire arrangement is recognized ratably over the
term of the arrangement.

The Company engages third party distributors to deliver some of its online marketing services to end
customers. In this context, the Company may provide cash incentives to distributors. The cash incentives are
accounted for as reduction of revenue in accordance with EITF Issue No. 01-9, Accounting for Consideration Given
by a Vendor to a Customer (Including a Reseller of the Vendor’s Products).

Cash received in advance from customers is recorded as customer deposits. The unused cash balances
remaining in customers’ accounts are included as a liability of the Company. Deferred revenue is recorded when
services are provided before the applicable revenue recognition criteria set forth in SAB 104 are fulfilled.

(7) Other services

The Company generates fees from the sale and license of its Search Appliance products, which includes
software and post-contract support. The Company recognizes revenue in accordance with Statement of Position
97-2, Software Revenue Recognition, as amended. For transactions in which the elements are not sold separately,
sufficient vendor-specific objective evidence of fair value does not exist for the allocation of revenue. As a result,
commencing with the delivery of the software, the fee for the entire arrangement is recognized ratably over the term
of the post-contract support arrangement.

Revenue is recognized net of value added tax (“VAT”) payable to, but includes the benefit of the rebate of VAT
on sale of enterprise search software received or receivable from, the Chinese tax authorities as part of the PRC
government’s policy of encouraging software development in the PRC. Sales of products in the PRC are subject to a
17% VAT. Companies that fulfill certain criteria set by the relevant authorities are entitled to a refund of VAT
equivalent to the excess over 3% of contracted amount paid in the month when output VAT exceeds input VAT. Such
VAT rebates are recorded on an accrual basis. The VAT rebate was RMB1.01 million and RMB0.20 million for the
years ended December 31, 2006 and 2007, respectively.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

The Company started the phase-out of abovementioned services in 2006 and completed in 2008. No VAT
rebate was recognized for the year ended December 31, 2008 as no software was delivered nor post-contract support
services were provided during the year.

Cost of Revenues

Cost of revenues consists primarily of business taxes and surcharges, traffic acquisition costs, bandwidth costs,

depreciation, payroll and related costs of operations.

The Company incurs business taxes and surcharges in connection with the provision of online marketing
services, technical and consulting service fees charged by Baidu Online to VIEs and other taxable services in the
PRC. According to EITF 06-3, How Taxes Collected from Customers and Remitted to Governmental Authorities
Should Be Presented in the Income Statement, the Company includes the business tax and surcharges incurred on its
online marketing revenues in cost of revenues. The business tax and surcharges in cost of revenues for the years
ended December 31, 2006, 2007 and 2008 were RMB51.83 million, RMB108.78 million and RMB200.09 million
(US$29.33 million), respectively. Traffic acquisition costs represent the amounts paid or payable to Baidu Union
members from which the Company generates revenues. These payments are primarily based on revenue sharing
arrangements under which the Company pays its Baidu Union members a percentage of the fees it earns from its
online marketing customers, primarily generated by click-throughs as a result of users of that member’s properties.

Advertising Expenses

Advertising expenses, primarily advertisements through media publications, are included in “Selling, general
and administrative expense” on the consolidated statements of income and are expensed when incurred. Advertising
expenses for the years ended December 31, 2006, 2007 and 2008 were RMB19.69 million, RMB19.83 million and
RMB29.22 million (US$4.28 million), respectively.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related costs. The Company has expensed
substantially all development costs included in the research and development of products and new functionality
added to the existing products as incurred, except for certain core technologies with alternative future uses.

Leases

Leases have been classified as either capital or operating leases. Leases that transfer substantially all the
benefits and risks incidental to the ownership of assets are accounted for as if there was an acquisition of an asset and
incurrence of an obligation at the inception of the lease. All other leases are accounted for as operating leases
wherein rental payments are expensed as incurred. The Company has no capital leases for the years ended
December 31, 2006, 2007 and 2008.

Income Taxes

The Company recognizes income taxes under the liability method. Deferred income taxes are recognized for
differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the
years in which the differences are expected to reverse. The Company records a valuation allowance against the
amount of deferred tax assets that it determines is not more likely than not of being realized. The effect on deferred
taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company adopted the provisions of FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty
in Income Taxes — an interpretation of FASB Statement No. 109, on January 1, 2007. FIN 48 clarified the
accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to
meet before being recognized in the financial statements. The Company did not incur a cumulative effect

adjustment upon adoption of FIN 48 nor did the standard have any impact on the Company’s financial statements for
the years ended December 31, 2007 and 2008. The Company has elected to classify interest and penalties related to
an uncertain tax position, if and when required, as part of income tax expense in the consolidated statements of
income. As of and for the years ended December 31, 2007 and 2008, no unrecognized tax benefits or interest and
penalties have been recognized.

In general, the PRC and Japanese tax authorities have up to five years to conduct examinations of the
Company’s tax filings. Accordingly, the PRC subsidiaries’ tax years 2004-2008 and the Japanese subsidiary’s tax
years 2006-2008 remain open to examination by the respective taxing jurisdictions.

Comprehensive Income

Comprehensive income is defined as the change in equity of the Company during a period from transactions
and other events and circumstances excluding transactions resulting from investments by owners and distributions
to owners. Comprehensive income is reported in the consolidated statements of shareholders’ equity. Accumulated
other comprehensive loss of the Company consists of the foreign currency translation adjustments.

Share-based Compensation

The Company adopted SFAS No. 123 (revised 2004) (“SFAS 123R”), Share-Based Payment, using the
modified prospective transition approach from January 1, 2006, prior to which the Company accounted for share-
based compensation arrangements with employees in accordance with the provisions of APB Opinion No. 25
(“APB 25”), Accounting for Stock Issued to Employees, and related interpretations thereof. Pursuant to SFAS 123R,
the Company recognized share-based compensation expense over the requisite service periods for any share-based
awards granted after December 31, 2005 based on the fair values of all share-based awards on the dates of grant. The
Company continues to account for share options that were granted prior to the initial public filing of the Company’s
F-1 registration statement with the SEC on July 12, 2005 but that remained unvested at December 31, 2005 under
the provision of APB 25. For share-based awards granted after the initial public filing but prior to January 1, 2006,
the compensation cost related to the unvested portion is recognized based on the grant date fair values of those
awards.

The adoption of SFAS 123R resulted in a cumulative benefit from accounting change of RMB4.60 million in
2006, which reflects the net cumulative impact of estimating future forfeitures in the determination of period
expense. As a result of adopting SFAS 123R, income before income taxes and net income for the year ended
December 31, 2006, were RMB9.10 million (US$1.17 million) and RMB4.49 million (US$0.58 million) less than
that had the Company continued to account for share-based compensation under APB 25. Furthermore, basic and
diluted earnings per Class A and Class B ordinary shares for the year ended December 31, 2006 were approximately
RMB0.13 and RMB0.13 (US$0.02) less than that had the Company continued to account for share-based
compensation under APB 25.

The Company recognizes share-based compensation after the date of adoption of SFAS 123R using the
accelerated method for all share-based awards issued prior to January 1, 2006, other than those options accounted
for under APB 25. The Company has elected to recognize share-based compensation after the date of adoption of
SFAS 123R using the straight-line method for all share-based awards issued after January 1, 2006, which results in
the recognition of less share-based compensation in the first several years of the vesting period compared to that
which would have been recognized had the Company used the accelerated method. Forfeitures have been estimated
based on historical experience and periodically reviewed.

The Company accounts for share awards issued to non-employees in accordance with the provisions of
SFAS 123R and EITF Issue No. 96-18 (“EITF 96-18”), Accounting for Equity Instruments That Are Issued to Other
Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. Under SFAS 123R and

BAIDU, INC.

EITF 96-18, the Company uses the Black-Scholes option pricing model method to measure the value of options
granted to non-employees at each vesting date to determine the appropriate charge to share-based compensation.

The Company adopted SEC Staff Accounting Bulletin No. 107 in 2006, which requires share-based com-

pensation to be presented in the same manner as cash compensation rather than as a separate line item.

Share Repurchase Program

On December 16, 2008, a resolution was passed during the 2008 annual general meeting of shareholders
approving the Company to repurchase of its Class A ordinary shares represented by American depositary shares
(“ADSs”) before the end of 2009. The repurchases can be made from time to time in the open market or in
negotiated transactions subject to market conditions, the trading price of ADSs and other factors. As part of its share
repurchase program, the Company entered into two separate share repurchase arrangements with a financial
institution as follows:

(a) In December 2008, the Company entered into a structured share repurchase program which requires the
Company to make an upfront cash payment in exchange for the right to receive the Company’s own ordinary
shares or cash at the expiration of the agreement, depending on the closing price of the Company’s ordinary share
at the maturity date. Upon settlement of the structured share repurchase program, the Company either (i) receives
the upfront cash payment returned with a premium if the closing market price of the Company’s ordinary share is
at or above a predetermined price or (ii) a predetermined number of the Company’s ordinary shares if the closing
market price is below the predetermined price. Pursuant to the structured share repurchase program, the
Company made an upfront payment of US$10 million to the financial institution on December 24, 2008. The
upfront cash payment was recorded in shareholders’ equity as a reduction to additional paid-in capital in
accordance with EITF Issue No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and
Potentially Settled in, a Company’s Own Stock. The settlement either in the form of cash or shares by the financial
institution at the maturity date will be treated as an equity transaction by the Company.

(b) In December 2008, the Company also entered into a preset share repurchase program which engages
the financial institution to act as a broker on behalf of the Company to repurchase ADSs in the open market based
on a predetermined quantity and price range. Pursuant to the preset share repurchase program, the Company
made an upfront payment of US$10 million to the financial institution on December 31, 2008 to repurchase up to
an aggregate of US$10 million of ADSs during an agreed period. The Company may cancel the preset repurchase
program with the financial institution at any time so long as the Company provides a three-day notice to the
financial institution. The upfront US$10 million cash has no restriction otherwise and can be withdrawn by the
Company at any time. The repurchased shares are considered cancelled under Cayman Islands law and the
difference between the par value and the repurchase price is debited to retained earnings.

Earning Per Share (“EPS”)

The Company computes earnings per Class A and Class B ordinary shares in accordance with SFAS No. 128
(“SFAS 128”), Earnings per Share, using the two class method. Under the provisions of SFAS 128, basic net income
per share is computed using the weighted average number of ordinary shares outstanding during the period except
that it does not include unvested ordinary shares subject to repurchase or cancellation. Diluted net income per share
is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares
outstanding during the period. Potentially dilutive securities have been excluded from the computation of diluted
net income per share if their inclusion is anti-dilutive Potential ordinary shares consist of the incremental ordinary
shares issuable upon the exercise of stock options and restricted shares subject to cancellation. The dilutive effect of
outstanding stock options and restricted shares is reflected in diluted earnings per share by application of the
treasury stock method. The computation of the diluted net income per share of Class A ordinary shares assumes the
conversion of Class B ordinary shares, while the diluted net income per share of Class B ordinary shares does not
assume the conversion of those shares.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

BAIDU, INC.

The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are
identical, except with respect to voting. As a result, and in accordance with EITF Issue No. 03-6, Participating
Securities and the Two-Class Method under FASB Statement No. 128, the undistributed earnings for each year are
allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings
for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are
allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the
computation of the diluted net income per share of Class A ordinary shares, the undistributed earnings are equal to
net income for that computation.

For the purposes of calculating the Company’s basic and diluted earnings per Class A and Class B ordinary
shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the
date of exercise of such options.

The following table sets forth the computation of basic and diluted net income per Class A and Class B
ordinary shares. (Amounts in thousands of Renminbi (“RMB”), and in thousands of U.S. Dollars (“US$”), except
for number of shares and per share data)

Recent Accounting Pronouncements

In December 2007, the FASB issued SFAS Statement No. 141 (revised 2007) (“SFAS 141R”), Business
Combinations. This statement establishes principles and requirements for how an acquirer recognizes and measures
in its financial statements the identifiable assets acquired, the liabilities assumed, any noncontrolling interest in the
acquiree and the goodwill acquired. SFAS 141R also establishes disclosure requirements to enable the evaluation of
the nature and financial effects of the business combination. SFAS 141R is effective for fiscal years beginning on or
after December 15, 2008. The impact of the adoption of SFAS 141R on the Company’s consolidated results of
operations and financial condition will be largely dependent on the size and nature of the business combinations
completed after the adoption of this statement.

In December 2007, the FASB issued SFAS No. 160 (“SFAS 160”), Noncontrolling Interests in Consolidated
Financial Statements — an amendment of ARB No. 51. This statement affects the entities that have an outstanding
noncontrolling interest in one or more subsidiaries or that deconsolidate a subsidiary. SFAS 160 is effective for
fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. The adoption of
SFAS 160 has no impact on the Company’s consolidated results of operations and financial condition.

In February 2008, the FASB issued FASB Staff Position (“FSP”) No. FAS 157-1, Application of FASB
Statement No. 157 to FASB Statement No. 13 and Other Accounting Pronouncements That Address Fair Value
Measurements for Purposes of Lease Classification or Measurement under Statement 13 and FSP No. 157-2,
Effective Date of FASB Statement No. 157, which collectively remove certain leasing transactions from the scope of
SFAS 157 and partially delay the effective date of SFAS 157 for one year for certain nonfinancial assets and
liabilities. In October 2008, the FASB issued FSP SFAS 157-3, Determining the Fair Value of a Financial Asset
When the Market for That Asset Is Not Active, which clarifies the application of SFAS No. 157 in an inactive market
and illustrates how an entity would determine fair value when the market for a financial asset is not active. The
adoption of FSP No. 157-1, FSP No. 157-2 and FSP No. 157-3 has no material impact on the Company’s
consolidated results of operations and financial condition.

In March 2008, the FASB issued SFAS No. 161 (“SFAS 161”), Disclosures about Derivative Instruments and
Hedging Activities, an amendment of FASB Statement No. 133 SFAS 161 applies to all derivative instruments and
related hedged items accounted for under SFAS No. 133 (“SFAS 133”), Accounting for Derivative Instruments and
Hedging Activities SFAS 161 requires entities to provide greater transparency about how and why an entity uses
derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS 133 and
its related interpretations, and how derivative instruments and related hedged items affect an entity’s financial
position, results of operations and cash flows. SFAS 161 is effective for financial statements issued for fiscal years
and interim periods beginning after November 15, 2008. The Company does not expect the adoption of SFAS 161 to
have any material effect on its consolidated results of operations and financial condition.

In April 2008, the FASB issued FSP No. FAS 142-3 (“FSP 142-3”), Determination of the Useful Life of
Intangible Assets. FSP142-3 amends the factors an entity should consider in developing renewal or extension
assumptions used in determining the useful life of recognized intangible assets under SFAS 142, and applies to
(1) intangible assets that are acquired individually or with a group of other assets and (2) both intangible assets
acquired in business combinations and asset acquisitions. FSP 142-3 also requires entities to disclose information
for all intangible assets, recognized as of and subsequent to the effective date of FSP 142-3 to provide effects of the
entity’s intent or ability to renew or extend the arrangement associated with the intangible assets on expected cash
flows associated with the intangible assets. FSP 142-3 is effective for intangible assets acquired after December 15,

In May 2008, the FASB issued SFAS No. 162 (“SFAS 162”), The Hierarchy of Generally Accepted Accounting

U.S. GAAP (the GAAP hierarchy). SFAS 162 became effective November 15, 2008. The Company does not expect
the adoption of SFAS 162 to have a material effect on its consolidated results of operations and financial condition.

In June 2008, the EITF issued EITF Issue No. 07-5 (“EITF 07-5”), Determining Whether an Instrument (or
Embedded Feature) Is Indexed to an Entity’s Own Stock. EITF 07-5 clarifies the determination of whether an
instrument (or an embedded feature) is indexed to an entity’s own stock, which would qualify as a scope exception
under SFAS 133, Accounting for Derivative Instruments and Hedging Activities. EITF 07-5 is effective for financial
statements issued for fiscal years beginning after December 15, 2008. EITF 07-5 does not permit early adoption for
an existing instrument. The Company does not expect the adoption of EITF 07-5 will have a material effect on its
consolidated results of operations and financial condition.

In June 2008, the FASB issued FSP EITF Issue No. 03-6-1(“FSP EITF 03-6-1”), Determining Whether
Instruments Granted in Share-Based Payment Transactions Are Participating Securities. FSP EITF 03-6-1 clarifies
that share-based payment awards that entitle their holders to receive nonforfeitable dividends or dividend
equivalents before vesting should be considered participating securities. FSP EITF 03-6-1 is effective for fiscal
years beginning after December 15, 2008 on a retrospective basis. The Company has not granted any share-based
payment awards that contain non-forfeitable rights to dividends or dividend equivalents before vesting since
incorporation. The Company is currently evaluating the potential impact, if any, of the adoption of EITF 03-6-1 on
its consolidated results of operations and financial condition.

In November 2008, the FASB ratified EITF Issue No. 08-7 (“EITF 08-7”), Accounting for Defensive Intangible
Assets, EITF 08-7 applies to defensive intangible assets, which are acquired intangible assets that the acquirer does
not intend to actively use but intends to hold to prevent its competitors from obtaining access to them. As these
assets are separately identifiable, EITF 08-7 requires an acquiring entity to account for defensive intangible assets
as a separate unit of accounting. Defensive intangible assets must be recognized at fair value in accordance with
SFAS 141R and SFAS 157. EITF 08-7 is effective for defensive intangible assets acquired in fiscal years beginning
on or after December 15, 2008. The Company is currently evaluating the potential impact, if any, of the adoption of
EITF 08-7 on its consolidated results of operations and financial condition.

Concentration of Risks

Concentration of credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk
primarily consist of cash and cash equivalents, short-term investments and accounts receivable. The Company
has RMB2.66 billion (US$390.39 million) in cash and cash equivalents, and short-term investments. The Company
has approximately RMB 2.21 billion (US$323.85 million) in cash, bank deposits and money market funds in the
PRC, which constitute about 83% of total cash and cash equivalents and short-term investments. Since the global
financial crisis during the third quarter of 2008, the risk of bankruptcy of those banks in which the Company has
deposits or investments has increased significantly. In the event of bankruptcy of one of these financial institutions,
it may be unlikely to claim its deposits or investments back in full. The Company continues to monitor the financial
strength of the financial institutions.

Accounts receivable are typically unsecured and are derived from revenue earned from customers in China.
The risk with respect to accounts receivables is mitigated by credit evaluations the Company performs on its
customers and its ongoing monitoring process of outstanding balances.

Business and economic risks

The Company participates in a dynamic high technology industry and believes that changes in any of the
following areas could have a material adverse effect on the Company’s future financial position, results of
operations or cash flows: changes in the overall demand for services and products; competitive pressures due to new
entrants; advances and new trends in new technologies and industry standards; changes in bandwidth suppliers;

changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regula-
tions; and risks associated with the Company’s ability to attract and retain employees necessary to support its
growth.

No customer or other Baidu Union member generated greater than 10% of total revenues in any of the periods

presented.

The Company’s operations could be adversely affected by significant political, economic and social uncer-

tainties in the PRC.

Currency convertibility risk

Substantially all of the Company’s businesses are transacted in RMB, which is not freely convertible into
foreign currencies. All foreign exchange transactions take place either through the People’s Bank of China or other
banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China.
Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires
submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.

Concentration of Risks

Foreign currency exchange rate risk

The Company’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents
and short-term investments denominated in the U.S. dollar. The functional currency of the Company is US$, and the
reporting currency is RMB. Since July 21, 2005, the RMB has been permitted to fluctuate within a narrow and
managed band against a basket of certain foreign currencies. The depreciation of the US$ against RMB was
approximately 6.47% in 2008. Any significant revaluation of RMB may materially and adversely affect the cash
flows, revenues, earnings and financial position, and the value of, and any dividends payable on, the ADS in
U.S. dollars. As a result, an appreciation of RMB against the U.S. dollar would result in foreign currency translation
losses when translating the net assets of the Company from the U.S. dollar into RMB.

The functional currency of the subsidiaries in Japan is Japanese Yen (“JPY”), and the reporting currency is
RMB. During 2008, JPY appreciated by approximately 15% against RMB. The appreciation of JPY against RMB
results in foreign currency translation gains when translating the net assets into RMB.

For the years ended December 31, 2006, 2007 and 2008, the net foreign currency translation loss resulting from
the translation from the respective functional currencies to the RMB reporting currency is recorded in the
Company’s other comprehensive loss was RMB28.25 million, RMB48.26 million and RMB27.60 million
(US$4.0 million) respectively.

gains and interest income of RMB0.34 million, RMB5.25 million and RMB8.75 million (US$1.28 million) in the
consolidated statements of income, respectively.

As of December 31, 2008, short-term investments of RMB140.03 million (US$20.53 million) are fixed rate
investments with the original maturity of less than one year. The fixed rate investments in commercial banks are

INCOME TAXES

The Company is incorporated in the Cayman Islands and conducts its primary business operations through the
subsidiaries and VIEs in the PRC and Japan. It also has intermediate holding companies in the British Virgin Islands
(“BVI”) and Hong Kong. Under the current laws of the Cayman Islands and BVI, the Company is not subject to tax
on income or capital gains. Additionally, upon payments of dividends by the Company to its shareholders, no
Cayman Islands and BVI withholding tax will be imposed. Under the Hong Kong tax laws, Baidu Hong Kong is
exempted from income tax on its foreign-derived income and there are no withholding taxes in Hong Kong on
remittance of dividends.

China

Prior to January 1, 2008, the Company’s subsidiaries and VIEs were governed by the Income Tax Law of the
People’s Republic of China concerning Foreign Investment Enterprises (the “FIE”) and Foreign Enterprises, and the
Enterprise Income Tax laws of the PRC respectively (the “Previous IT Law”). Under the Previous IT Law, the
Company’s PRC subsidiaries and VIEs were generally subjected to enterprise income taxes at a statutory rate of
33% (30% state income tax plus 3% local income tax) while certain preferential tax treatments were granted for
qualified businesses. The Company’s PRC subsidiaries were entitled to preferential tax rates and special tax
holidays.

BAIDU, INC.

(cid:129) Baidu Online, being a foreign invested enterprise, was recognized as a “Technologically Advanced
Enterprise” by the Beijing Municipal Bureau of Commerce and thus entitled to a preferential tax rate of
10% from 2006 to 2007.

(cid:129) Baidu China, being a foreign invested enterprise, has been granted “Software Enterprise” status and thus
entitled to a “tax holiday” for a full exemption from EIT from 2006 to 2007, and a 50% tax reduction (at
12.5%) from 2008 to 2010.

(cid:129) Baidu Times, being a foreign invested enterprise, had been recognized as a “High and New Technology
Enterprise” and thus entitled to a reduced EIT rate of 15% upon expiration of the tax holiday, as well as
exemption from local income tax. The tax holiday granted to Baidu Times was for a full exemption from EIT
from 2006 to 2008, and a 50% tax reduction (at 7.5%) from 2009 to 2011.

On March 16, 2007, the National People’s Congress enacted the Enterprise Income Tax Law (“the New EIT
Law”), which became effective on January 1, 2008 and has replaced the previous separate income tax laws for
domestic enterprises and FIEs by adopting an unified 25% enterprise income tax rate applicable to all resident
enterprises in China, including FIEs and foreign enterprises operating in the PRC, except for certain entities that are
eligible to tax holidays and entities enjoying tax holidays under the Previous IT Law grandfathered by the New EIT
Law. In accordance with the implementation rules of the New EIT Law, a qualified “High and New Technology
Enterprise” under the New EIT Law will be granted the preferential tax rate of 15%. Baidu Online and Baidu Times
are recognized as “High and New Technology Enterprises” under the New EIT Law by relevant authorities effective
from fiscal year 2008. Therefore, Baidu Online enjoys the reduced EIT rate of 15% and Baidu Times is eligible to
enjoy its remaining tax holiday granted under the Previous IT Law. Baidu China, as a certified “Software Company”
in Pudong Shanghai, has been entitled to 2-year exemption for years 2006 and 2007 and subsequent 50% tax rate
reduction for years 2008 to 2010 with 25% tax rate used as the basis for the 3-year 50% reduction.

Under the New EIT Law, dividends paid by a FIE to any of its foreign non-resident enterprise investors are
subject to a 10% withholding tax, which were exempt under the Previous IT Law. Thus, the dividends, if and when
payable by Baidu Online to Baidu Cayman, would be subject to 10% withholding tax. A lower tax rate will be
applied if such foreign non-resident enterprise investor’s jurisdiction of incorporation has signed a tax treaty or
arrangement for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on
income with China. The above mentioned tax arrangement was signed between PRC and Hong Kong. Thus, the
dividends, if and when payable by Baidu Times and Baidu China to Baidu HK, would be subject to 5% withholding
tax rather than statutory rate of 10%. Furthermore, pursuant to the interpretation under Article 4 of Cai Shui [2008]
Circular No. 1 of the New EIT Law, dividends from earnings created prior to 2008 but distributed after 2008 are not
subject to withholding income tax.

The New Income Tax Law stipulates that a resident enterprise, which includes an enterprise established outside
of the PRC with management and control located in the PRC, will be subject to PRC income tax on its worldwide
income. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside
the PRC should be deemed a resident enterprise, the Company and its subsidiaries registered outside the PRC will
be subject to the PRC income tax at a rate of 25%. The Company will continue to monitor its tax status.

Japan

Baidu Japan with a paid-in capital in excess of JPY100 million is subject to national income tax of 30%. Baidu
Japan is also subject to inhabitants tax, assessed by both prefectures and municipalities. Inhabitants tax is computed
as a percentage of national income tax. The per capita tax is based on the company’s capitalization and the number
of employees. In addition, Baidu Japan is subject to a corporate enterprise tax on a pro forma basis based on the
amount of taxable profit subject to the corporate tax, added-value components, (e.g., labor costs, net interest and
rental payments, income/loss for current year) and a capital component. Baidu Japan has been in a cumulative loss
position since its inception.

* The statutory EIT rate was 33% for the years ended December 31, 2006 and 2007, and was changed to 25% for

the year ended December 31, 2008.

** Baidu Online and Baidu China enjoyed an additional tax incentive relating to its research and development
expenses. The Company has claimed an additional tax deduction amounting to 50% of the current year’s
research and development expenses. The amount that exceeds the current year’s taxable profit would be able to
be carried forward for up to the following five years’ utilization. In 2006, 2007 and 2008, the Company has no
deductible research and development expenses carried forward.

The Company’s effective tax rate increased from fiscal year 2007, primary due to Baidu China had been
entitled to tax exemption for year 2007 and subsequently was subject to 12.5% tax rate for year 2008; also due to the
cessation of reinvestment credit under the New EIT Law. Prior to the New EIT Law, a foreign investor may be
eligible for a tax refund when it reinvests its share of accumulated profits from an existing FIE to increase the
registered capital of the existing FIE. In 2007, Baidu Holdings obtained such a reinvestment tax refund, as it
increased the registered capital in Baidu Online by reinvesting the retained earnings of Baidu Online. The
preferential tax refund was repealed in the New EIT Law.

The Company does not believe that sufficient positive evidence exists to conclude that the recoverability of
Baidu Japan and Baidu Hong Kong’s net deferred tax assets is more likely than not to be realized. Consequently, the
Company has provided full valuation allowances on the related net deferred tax assets.

As of December 31, 2008, the Company had net operating losses of approximately RMB183.64 million
(US$26.92 million) from Baidu Japan, Baidu HK and BaiduPay, which can be carried forward to offset future net
profit for income tax purposes. The Japan net operating loss will expire beginning 2015; the PRC net operating loss
will expire beginning 2014; and the HK net operating loss can be carried forward without expiration date.

The Company has evaluated its income tax uncertainty under FIN 48. FIN 48 clarifies the accounting for
uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being
recognized in the financial statements. The Company has elected to classify interest and penalties related to an
uncertain tax position, if and when required, as part of income tax expense in the consolidated statements of
operations. As of the twelve month period ended December 31, 2008, there is no significant tax uncertainty impact
on its financial position and result of operations.

The Company did not provide for deferred income taxes and foreign withholding taxes on the undistributed
earnings of foreign subsidiaries and its VIEs as of December 31, 2008. The Company intends to permanently

reinvest foreign subsidiaries’ earnings. If these foreign earnings were to be repatriated in the future, the related tax
liability may be reduced by any foreign income taxes previously paid on these earnings. In the case of its VIEs,
undistributed earnings were insignificant as of each of the balance sheet dates. Determination of the amount of
unrecognized deferred tax liability related to these earnings is not practicable.

11. EMPLOYEE DEFINED CONTRIBUTION PLAN

Full time employees of subsidiaries of the Company in the PRC participate in a government mandated multi-
employer defined contribution plan pursuant to which certain pension benefits, medical care, unemployment
insurance, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations
require that the subsidiaries of the Company make contributions to the government for these benefits based on
certain percentages of the employees’ salaries. The Company has no legal obligation for the benefits beyond the
required contributions. The total amounts for such employee benefits, which were expensed as incurred, were
RMB32.62 million, RMB55.12 million and RMB98.18 million (US$14.39 million) for the years ended
December 31, 2006, 2007 and 2008, respectively.

12. COMMITMENTS AND CONTINGENCIES

Capital commitments

The Company’s capital commitments relate primarily to leasehold improvements and building construction.
Total capital commitments contracted but not yet reflected in the financial statements amounted to RMB149.41 million
(US$21.90 million) at December 31, 2008. All of these capital commitments are to be fulfilled within the next year.

Operating lease commitments

The Company leases facilities in the PRC under non-cancelable operating leases expiring on different dates.
Payments under operating leases are expensed on a straight-line basis over the periods of the respective leases. Total
rental expense under all operating leases was RMB17.26 million, RMB45.41 million and RMB68.86 million
(US$10.09 million) for the years ended December 31, 2006, 2007 and 2008, respectively.

Future minimum payments under non-cancelable operating leases with initial terms of one-year or more

consist of the following at December 31, 2008:

Litigation

Baidu Netcom, Baidu China and Baidu Online were involved in certain cases pending in various PRC courts
and arbitration as of December 31, 2008. These cases include copyright infringement cases, unfair competition
cases, and defamation cases, among others. Adverse results in these lawsuits may include awards of damages and
may also result in, or even compel, a change in the Company’s business practices, which could result in a loss of
revenue or otherwise harm the business of the Company.

As of December 31, 2008, the plaintiffs associated with various cases claimed an aggregate remedy of
RMB67.3 million (US$9.86 million). Although the results of litigation and claims cannot be predicted with

13. ORDINARY SHARES

Upon completion of the initial public offering (“IPO”) in August 2005, 16,648,877 Class B Ordinary shares
were issued upon conversion of all convertible preferred shares. In addition, immediately following the closing of
the IPO, the Memorandum and Articles of Association were amended and restated such that the authorized share
capital consisted of 870,400,000 ordinary shares at a par value of US$0.00005 per share, of which
825,000,000 shares were designated as Class A ordinary shares, 35,400,000 as Class B ordinary shares, and
10,000,000 shares designated as preferred shares. The 10,000,000 preferred shares were converted into ordinary
shares in 2005. The rights of the holders of Class A and Class B ordinary shares are identical, except with respect to
voting and conversion rights. Each share of Class A ordinary shares is entitled to one vote per share and is not
convertible into Class B ordinary shares under any circumstances. Each share of Class B ordinary shares is entitled
to ten votes per share and is convertible into one Class A ordinary share at any time by the holder thereof. Upon any
transfer of Class B ordinary shares by the holder thereof to any person or entity that is not an affiliate of such holder,
such Class B ordinary shares would be automatically converted into an equal number of Class A ordinary shares.
There were 12,355,318, 2,133,176 and 122,856 Class B ordinary shares transferred to Class A ordinary shares in
2006, 2007 and 2008, respectively.

As of December 31, 2008 there were 25,641,847 and 8,873,986 Class A and Class B ordinary shares

outstanding, respectively.

14. RETAINED EARNINGS

In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of
association, the Company’s PRC subsidiaries, being foreign invested enterprises established in China, are required
to provide for certain statutory reserves, namely a general reserve fund, an enterprise expansion fund and a staff
welfare fund and a bonus fund, all of which are appropriated from net profit as reported in their PRC statutory
accounts. Each of the Company’s subsidiaries is required to allocate at least 10% of its after-tax profits to a general
reserve fund until such fund has reached 50% of their respective registered capital. Appropriations to the enterprise
expansion fund and staff welfare and bonus funds are at the discretion of the board of directors of the Company’s
subsidiaries.

In accordance with the China Company Laws, the Company’s VIEs must make appropriations from their after-
tax profits as reported in their PRC statutory accounts to non-distributable reserve funds, namely a statutory surplus
fund, a statutory public welfare fund and a discretionary surplus fund. Each of the Company’s VIEs is required to
allocate at least 10% of its after-tax profits to the statutory surplus fund until such fund has reached 50% of their
respective registered capital. Appropriation to the statutory public welfare fund is 5% to 10% of the after-tax profits
as reported in the PRC statutory accounts. Effective from January 1, 2006, under the revised China Company Laws,
appropriation to the statutory public welfare fund is no longer mandatory. Appropriations to the discretionary
surplus fund are made at the discretion of the Company’s VIEs.

General reserve and statutory surplus funds are restricted to set-off against losses, expansion of production and
operation and increasing registered capital of the respective company. Staff welfare and bonus fund and statutory
public welfare funds are restricted to capital expenditures for the collective welfare of employees. The reserves are

15. SHARE-BASED AWARDS PLAN

In January 2000, the Company adopted the 2000 Option Plan (the “2000 Plan”). The 2000 Plan provides for the
granting of share options and restricted ordinary shares to employees and consultants of the Company. Options
granted under the 2000 Plan may be either incentive share options or nonqualified share options. Incentive share
options (“ISO”) may be granted only to Company employees (including officers and directors who are also
employees). Nonqualified share options (“NSO”) may be granted to Company employees and consultants. The
Company has reserved 5,040,000 ordinary shares for issuance under the 2000 Plan. Under the 2000 Plan, which
expires in ten years, options granted generally vest 25% after the first year of service and ratably each month over
the remaining 36-month period.

Under the 2000 Plan, the employees may exercise their options immediately, if such provisions are provided in
the award agreement, but the Company has a right to repurchase unvested shares at the amount equal to the original
purchase price paid by the grantee for each such share. The right to repurchase lapses at the rate of at least twenty
percent of the shares subject to the award per year over five years from the date the award is granted (without respect
to the date the award was exercised or became exercisable). Such repurchase right is exercisable at any time
(i) during the 90-day period following employee termination date, or (ii) during the 90-day period following an
exercise of the option that occurs after employee termination date. The contractual term of options granted is
generally five years.

In December 2008, the Company amended the 2000 Plan by adding a new section regarding adjustment of
exercise price. The exercise price per share subject to an option may be amended or adjusted in the absolute
discretion of the 2000 Plan administrator, which is the Board of Directors, and the determination of which shall be
final, binding and conclusive. A downward adjustment of the exercise prices shall be effective without the approval
of the Company’s shareholders or the approval of the affected grantees.

Starting from February 15, 2006, the Company has granted restricted Class A ordinary shares (“Restricted
Shares”) of the Company under the 2000 Plan, which generally vest 50% after the first year of service and ratably
each month over the remaining 12-month period. Terms for Restricted Shares are the same as share options except
that Restricted Shares do not require exercise and generally have a two-year vesting term. The contractual term of
Restricted Shares granted is generally five years.

In December 2008, the Company adopted 2008 share incentive plan (the “2008 Plan”). The 2008 Plan provides
for the granting of share incentives, which include ISO, restricted shares and any other form of award pursuant to the
2008 Plan, to members of the board, employees and consultants of the Company. The Company may grant ISOs
only to its employees. The Company has reserved 3,428,777 ordinary shares for issuance under the 2008 Plan,

which expires in ten years. The vesting schedule, time and condition to exercise options will be determined by the
compensation committee. The term of the options may not exceed ten years from the date of the grant, except that
five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of
the Company’s share capital.

Under the 2008 Plan, the exercise price per share subject to an option may be amended or adjusted in the
absolute discretion of the compensation committee, and the determination of which shall be final, binding and
conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment of the
exercise prices shall be effective without the approval of the Company’s shareholders or the approval of the affected
grantees. If the Company grants an ISO to an employee who, at the time of that grant, owns shares representing more
than 10% of the voting power of all classes of the Company’s share capital, the exercise price cannot be less than
110% of the fair market value of the Company’s ordinary shares on the date of that grant.

The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock

price on the last trading day in 2008 and the exercise price.

Total intrinsic value of options exercised for the three years ended December 31, 2006, 2007 and 2008 was

RMB396.32 million, RMB559.59 million and RMB465.25 million (US$68.19 million), respectively.

As of December 31, 2008, there was RMB43.50 million (US$6.38 million) unrecognized share-based
compensation cost related to share options. That deferred cost is expected to be recognized over a weighted-
average vesting period of 2.04 years. To the extent the actual forfeiture rate is different from original estimate, actual
share-based compensation costs related to these awards may be different from the expectation.

Restricted shares activity for the year ended December 31, 2008 was as follows:

weighted-average vesting period of 1.32 years. To the extent the actual forfeiture rate is different from the original
estimate, actual share-based compensation costs related to these awards may be different from the expectation.

The fair value of each option award was estimated on the date of grant using the Black-Scholes Method
valuation model. The volatility assumption was estimated based on the volatilities of comparable public companies
and limited historical volatility of the Company’s share price applying the guidance provided by Staff Accounting
Bulletin No. 107, Share-Based Payment. Assumptions about the expected term were based on the vesting and
contractual terms, employee demographics and the expected term of the similar companies. The Company
considered the comparable data because the Company has limited relevant historical information to support the
expected exercise behavior of employees who have been granted options. This relevant historical information is
limited because the Company has been a public company only since August 2005. The risk-free rate for periods
within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The following table presents the assumptions used to estimate the fair values of the share options granted in the

periods presented:

In addition, the Company applies an expected forfeiture rate in determining the grant date fair value of the
option grants. The estimation of the forfeiture rate was based primarily upon historical experience of employee
turnover. To the extent the Company revises this estimate in the future, the share-based payments could be
materially impacted in the quarter of revision, as well as in following quarters. During the year ended December 31,
2008, the Company decreased the forfeiture rate for both the executive group and the employee group primarily due
to changes in historical employee turnover rates.

Due to the increase of share-based awards granted in 2008, the share-based compensation cost increased by
approximately RMB2.18 million (US$0.32 million) for the year ended December 31, 2008 comparing to the
preceding year.

16. RELATED PARTY TRANSACTIONS

Employees who exercise their options with cash will be required to pay individual income tax (“IIT”) through
the Company. As of December 31, 2008, the Company accrued withholding individual income tax for one
employee, who is also one of the major shareholders, of RMB10.7 million (US$1.6 million). The balance was
subsequently paid by the employee to the tax authority through the Company in February 2009. No balances were
due from any other shareholders, officers or directors as of December 31, 2006 and 2007.

17. SEGMENT REPORTING

In accordance with SFAS No. 131, Disclosures about segments of an Enterprise and Related Information, the
Company’s chief operating officer relies upon consolidated results of operations when making decisions about
allocating resources and assessing performance of the Company; hence, the Company has only one single operating
segment. The Company does not distinguish between markets or segments for the purpose of internal reporting.

The Company’s long-lived assets and revenue are substantially all located in and derived from the PRC.

18. FAIR VALUE MEASUREMENT

Effective January 1, 2008, the Group adopted SFAS No. 157 (“SFAS 157”), Fair Value Measurement.
SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair
value measurements. Although the adoption of SFAS 157 did not impact the Group’s financial condition, results of
operations, or cash flow, SFAS 157 requires additional disclosures to be provided on fair value measurement.

SFAS 157 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value

as follows:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in

active markets.

Level 2 — Include other inputs that are directly or indirectly observable in the marketplace.

Level 3 — Unobservable inputs which are supported by little or no market activity

SFAS 157 describes three main approaches to measuring the fair value of assets and liabilities: (1) market
approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant
information generated from market transactions involving identical or comparable assets or liabilities. The income

BAIDU, INC.

approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is
based on the value indicated by current market expectations about those future amounts. The cost approach is based
on the amount that would currently be required to replace an asset.

In accordance with SFAS 157, the Company measures cash equivalents, short-term investments at fair value.
Cash equivalents and short-term investments are classified within Level 1 or Level 2. This is because cash
equivalents and short-term investments are valued using either quoted market prices or models utilizing market
observable inputs.

Assets measured at fair value on a recurring basis are summarized below (in thousands):

New Subsidiary

In February 2009, Baidu HK established a wholly-owned subsidiary, Baidu Interaction (Shenzhen) Network
Technology Co., Ltd. in Shenzhen of the PRC. The new subsidiary offers Internet search solutions and online
marketing solutions, develops and markets scaleable web application software and provides related services.

Share Repurchase Programs

As of February 28, 2009, the Company has repurchased 32,740 ordinary shares from the open market through the
preset share repurchase program with a financial institution for an aggregate purchase price of RMB24.35 million
(US$3.57 million), including transaction cost of RMB6,700.00 (US$982.00). The repurchased shares are considered
cancelled under Cayman Islands law and the difference between the par value and the repurchase price is debited to
retained earnings.

On March 27, 2009, the Company received its US$10 million upfront cash payment with a premium of
US$0.84 million from the financial institution under the structured share repurchase program as the closing market
price of the Company’s ordinary share at the maturity date is above the predetermined price. The US$10.84 million
received by the Company was treated as an equity transaction and was credited to additional paid-in capital.

Subsequent to December 31, 2008, the Company entered into a structured stock repurchase transaction of
additional US$20 million. Based on the market condition upon maturity in the second quarter, the transaction will
be settled either in cash or by shares.

Option Modification

In February 2009, the Company cancelled certain options previously granted to certain executives with the
exercise price significantly higher than the current fair market value, and concurrently re-granted the same number
of options at the current fair market value. The vesting of the replacement option starts from the date of grant. The
expiration date is five years from the grant date. All other terms remain the same as the original option. The
cancellation and re-grant is intended to provide incentives for these executives. In accordance with FAS 123(R),
cancellation of an award accompanied by the concurrent grant of a replacement award shall be accounted for as a
modification of the terms of the cancelled award. Therefore, incremental compensation cost shall be measured as
the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation
date. The total compensation cost measured at the date of cancellation and replacement shall be the portion of the
grant-date fair value of the original award for which the requisite service is expected to be rendered (or has already
been rendered) at that date plus the incremental cost resulting from the cancellation and replacement. The Company
will amortize the total compensation cost as a result of the modification on a straight-line basis over the vesting term
of the replacement option.
