NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Google Inc. and Summary of Accounting Policies

Nature of Operations

We were incorporated in California in September 1998. We were re-incorporated in the State of Delaware in August 2003. We provide highly targeted advertising and global internet search solutions as well as intranet solutions via an enterprise search appliance.

Basis of Consolidation

The Condensed Consolidated Financial Statements include the accounts of Google and our wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.

Unaudited Interim Financial Information

The accompanying Condensed Consolidated Balance Sheet as of June 30, 2007, the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2006 and 2007, and the Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2006 and 2007 are unaudited. These unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles. In our opinion, the unaudited interim Condensed Consolidated Financial Statements include all adjustments of a normal recurring nature necessary for the fair presentation of our financial position as of June 30, 2007, our results of operations for the three and six months ended June 30, 2006 and 2007, and our cash flows for the six months ended June 30, 2006 and 2007. The results of operations for the three and six months ended June 30, 2007 are not necessarily indicative of the results to be expected for the year ending December 31, 2007.

These unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes included in our 2006 Annual Report on Form 10-K filed on March 1, 2007.

Use of Estimates

The preparation of interim Condensed Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ materially from these estimates. On an ongoing basis, we evaluate our estimates, including those related to the accounts receivable, fair values of marketable and non-marketable securities, fair values of intangible assets and goodwill, useful lives of intangible assets and property and equipment, fair values of options to purchase our common stock, traffic acquisition costs, and income taxes, among others. We base our 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. We engage third-party valuation consultants to assist management in the allocation of the purchase price of significant acquisitions.

Effect of Recent Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS No. 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. This statement is effective for us beginning January 1, 2008. We are currently evaluating the impact of the adoption of SFAS No. 157 on our financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities- including an Amendment of FASB Statement No. 115, which allows an entity to choose to measure certain financial instruments and liabilities at fair value. Subsequent measurements for the financial instruments and liabilities an entity elects to fair value will be recognized in earnings. SFAS No. 159 also establishes additional disclosure requirements. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007, with early adoption permitted provided that the entity also adopts SFAS No. 157. We are currently evaluating whether to adopt SFAS No. 159 and, if adopted, the impact of such adoption.

Note 5. Acquisitions

During the six months ended June 30, 2007, we completed ten acquisitions. One of these transactions was accounted for as an asset purchase in accordance with EITF Issue No. 98-3, Determining Whether a Nonmonetary Transaction Involves Receipt of Productive Assets or of a Business, as the acquired company was considered to be a development stage enterprise. The remaining nine transactions were accounted for as business combinations. The total initial purchase price for these transactions was $183.6 million and was paid or will be paid in cash. In addition, we are obligated to make additional cash payments of up to $41.8 million if certain performance targets are met through 2010. Since these contingent payments are based on the achievement of performance targets, actual payments may be substantially lower. A portion of these contingent payments will be accounted for as goodwill, and the remaining amounts will be expensed, when and if earned.

In addition, during the six months ended June 30, 2007, we capitalized intangible assets of $7.4 million, paid in cash, related to milestone payments for acquisitions completed prior to 2007.

The following table summarizes the allocation of the purchase price for all of the above acquisitions (in thousands):

Goodwill expected to be deductible for tax purposes is $3.1 million.

Patents and developed technology, customer contracts and other intangible assets have a weighted-average useful life of 3.2 years from the date of acquisition.

Purchased in-process research and development was expensed at the time of the acquisitions because technological feasibility had not been established and no future alternative uses existed. This amount was included in research and development expenses on the accompanying Condensed Consolidated Statements of Income.

Note 6. Goodwill and Other Intangible Assets

The changes in the carrying amount of goodwill for the six months ended June 30, 2007, are as follows (in thousands):

Table of Contents

The goodwill adjustment of $47.0 million was primarily a result of an increase to an estimate of employee termination costs and a contingent payment earned upon the achievement of certain performance targets related to business combinations initially recorded in 2006.

Information regarding our acquisition-related intangible assets that are being amortized is as follows (in thousands):

Patents and developed technology and tradenames, customer contracts and other have weighted-average useful lives from the date of purchase of 3.2 and 4.2 years. Amortization expense of acquisition-related intangible assets for the three and six months ended June 30, 2006 were $15.9 million and $31.3 million. Amortization expense of acquisition-related intangible assets for the three and six months ended June 30, 2007 were $34.3 million and $70.6 million.

Amortization expense for acquisition-related intangible assets on our June 30, 2007 Condensed Consolidated Balance Sheet for the remainder of 2007 and each of the next four years and thereafter is as follows (in thousands):

Legal Matters

Companies have filed trademark infringement and related claims against us over the display of ads in response to user queries that include trademark terms. The outcomes of these lawsuits have differed from jurisdiction to jurisdiction. Courts in France have held us liable for allowing advertisers to select certain trademarked terms as keywords. We are appealing those decisions. We were also subject to two lawsuits in Germany on similar matters where the courts held that we are not liable for the actions of our advertisers prior to notification of trademark rights. We are litigating or have recently litigated similar issues in other cases in the U.S., France, Germany, Israel, Italy, Austria and Australia.

We have also had copyright claims filed against us alleging that features of certain of our products and services, including Google Web Search, Google News, Google Video, Google Image Search, Google Book Search and YouTube, infringe their rights. Adverse results in these lawsuits may include awards of substantial monetary damages, costly royalty or licensing agreements or orders preventing us from offering certain functionalities, and may also result in a change in our business practices, which could result in a loss of revenue for us or otherwise harm our business. In addition, any time one of our products or services links to or hosts material in which others allegedly own copyrights, we face the risk of being sued for copyright infringement or related claims. Because these products and services comprise the majority of our products and services, our business could be harmed in the event of an adverse result in any of these claims.

We are also a party to other litigation and subject to claims incident to the ordinary course of business, including intellectual property claims (in addition to the trademark and copyright matters noted above), labor and employment claims, breach of contract claims, tax and other matters.

Although the results of litigation and claims cannot be predicted with certainty, we believe that the final outcome of the matters discussed above will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows.

Income Taxes

We are currently under audit by the Internal Revenue Service and various other tax authorities. We have reserved for potential adjustments to our provision for income taxes that may result from examinations by, or any negotiated agreements with, these tax authorities, and we believe that the final outcome of these examinations or agreements will not have a material effect on our results of operations. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities would result in the recognition of tax benefits in the period we determine the liabilities are no longer necessary. If our estimates of the federal, state, and foreign income tax liabilities are less than the ultimate assessment, a further charge to expense would result.
