OVERVIEW Yahoo! Inc. ("Yahoo!" or the "Company") is a global Internet media company that offers a branded network of comprehensive information, communication, and shopping services to millions of users daily. As the first online navigational guide to the World Wide Web (the "Web"), www.yahoo.com is a leading guide in terms of traffic, advertising, household and business user reach, and is one of the most recognized brands associated with the Internet. The Company was incorporated in California on March 5, 1995 and commenced operations on that date. In August 1995, the Company commenced selling advertisements on its Web pages and recognized its initial revenues. In April 1996, the Company completed its initial public offering. On October 20, 1997, the Company completed the acquisition of Four11 Corporation ("Four11"), a privately-held online communications and Internet directory company. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 6,022,880 shares of Yahoo! Common Stock for all of Four11's outstanding shares and assumed 593,344 options and warrants to purchase Yahoo! Common Stock. During the quarter ended December 31, 1997, the Company recorded a one-time charge of $3.9 million for the acquisition. These costs consisted of investment banking fees, legal and accounting fees, redundancy costs, and certain other expenses directly related to the acquisition. The consolidated financial statements for the three years ended December 31, 1998 and the accompanying notes reflect the Company's financial position and the results of operations as if Four11 was a wholly-owned subsidiary of the Company since inception. On June 10, 1998, the Company completed the acquisition of all outstanding shares of Viaweb Inc. ("Viaweb"), a provider of software and services for hosting online stores, through the issuance of 1,574,364 shares of Yahoo! Common Stock. All outstanding options to purchase Viaweb common stock were converted into options to purchase 244,504 shares of Yahoo! Common Stock. The acquisition was accounted for as a purchase in accordance with the provisions of Accounting Principles Board Opinion ("APB") No. 16. Under the purchase method of accounting, the purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of the acquisition. Results of operations for Viaweb have been included with those of the Company for periods subsequent to the date of acquisition. The total purchase price of the acquisition was $48.6 million including acquisition expenses of $1.8 million. Of the purchase price, $15.0 million was assigned to in-process research and development and expensed upon the consummation of the acquisition. The purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values as determined by the Company and pursuant to discussions with the Staff of the Securities and Exchange Commission (the "Staff"). Among the factors considered in discussions with the Staff in determining the amount of the allocation of the purchase price to in-process research and development were various factors such as estimating the stage of development of each in-process research and development project at the date of acquisition, estimating cash flows resulting from the expected revenues generated from such projects, and discounting the net cash flows, in addition to other assumptions. The remaining identified intangibles, including the value of purchased technology and other intangibles will be amortized on a straight-line basis over three and seven years, respectively. Amortization expense of purchased technology and other intangible assets was $2.9 million and $2.0 million, respectively, for the year ended December 31, 1998. In addition, other factors were considered in discussions with the Staff in determining the value assigned to purchased in-process technology such as research projects in areas supporting the online store technology (including significant enhancement to the ability of the product to support multiple users and multiple servers), developing functionality to support the ability to process credit card orders, and enhancing the product's user interface by developing functionality that would allow the product to be used outside of the United States. If none of these projects is successfully developed, the Company's sales and profitability may be adversely affected in future 2

periods. Additionally, the failure of any particular individual project in process could impair the value of other intangible assets acquired. The Company began to benefit from the purchased in-process technology in late 1998. Yahoo! is continuing the development efforts associated with online store technology, credit card processing and to a lesser extent international functionality. The development efforts with respect to the online store technology and credit card processing are on schedule with Yahoo!'s original assumptions with various features having been introduced as of December 31, 1998. Given the complexities of completing the international functionality, Yahoo! continues to make progress in the development of these features and now expects to be substantially complete by the end of June 1999. On July 17, 1998, the Company completed the acquisition of WebCal Corporation ("WebCal"), a privately-held developer and marketer of Web-based calendaring and scheduling products, and publisher of EventCal, a comprehensive database of world-wide public events. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 541,908 shares of Yahoo! Common Stock for all of WebCal's outstanding shares. The historical operations of WebCal are not material to the Company's financial position or results of operations, therefore, prior period financial statements have not been restated for this acquisition. On October 20, 1998, the Company acquired Yoyodyne Entertainment, Inc. ("Yoyodyne"), a privately-held, direct marketing services company. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 561,244 shares of Yahoo! Common Stock and options and warrants to purchase Yahoo! Common Stock for all of Yoyodyne's outstanding shares, options, and warrants. The consolidated financial statements for the three years ended December 31, 1998 and the accompanying notes reflect the Company's financial position and the results of operations as if Yoyodyne was a wholly-owned subsidiary of the Company since inception. During October 1998, the Company recorded a one-time charge of $2.1 million for acquisition-related costs. These costs consisted of broker fees, legal and accounting fees, and certain other expenses directly related to the acquisition. On December 17, 1998, the Company completed the acquisition of all of the outstanding shares of HyperParallel, Inc. ("HyperParallel"), a company specializing in data analysis, through the issuance of 74,856 shares of Yahoo! Common Stock and approximately $700,000 of cash totaling $8.1 million including acquisition costs. The acquisition was accounted for as a purchase in accordance with APB 16. Under the purchase method of accounting, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of the acquisition. Results of operations for HyperParallel have been included with those of the Company for periods subsequent to the acquisition. Approximately $2.3 million of the total purchase price was allocated to in-process research and development. This amount was developed by estimating the stage of development of each in-process research and development project at the date of the acquisition, estimating incremental cash flows generated from such projects, and discounting the net cash flows back to their present value using a discount rate of 35%, which represents a premium to the Company's cost of capital to take into account the uncertainty surrounding the successful development of the purchased in-process technology. The projections were based on management's estimates of market size and growth, expected trends in advertising and technology, expected research and development and selling and general administrative expenditures, and the expected timing of new product introductions. Approximately $1.2 million of the total purchase price was allocated to existing technology which is being amortized over 3 years. The value of the existing technology was developed based on similar assumptions using a discount rate of 25%. The projections used in developing the values should not be considered an accurate predictor of future performance for several reasons, including the consideration of many factors outside the control of the Company. The remaining purchase price of approximately $4.6 million was allocated to goodwill 3

which is being amortized over 7 years. Tangible assets acquired and liabilities assumed were not material to the Company's financial statements. The value assigned to purchased in-process technology was determined by identifying three research projects in-progress as of the acquisition date. These three research projects in-progress focus on technologies surrounding search tools. Two of the application oriented development projects were 70% and 20% complete as of the acquisition date. These projects are expected to be completed in the first and fourth quarters, respectively, of 1999. The remaining project relates to the next release of the current search tool which was approximately 20% complete as of the acquisition date and is expected to be completed in the fourth quarter of 1999. Future research and development costs to be incurred on the individual in-process projects are not expected to be material to Yahoo!'s financial position or results of operations. In addition, if none of these projects were successfully developed, Yahoo!'s revenues and profitability would not be materially adversely affected. On January 28, 1999, the Company announced the signing of a definitive agreement to acquire GeoCities, a publicly traded Internet company. Under the terms of the acquisition, which will be accounted for as a pooling of interests, the Company will exchange approximately 21,254,000 shares of Yahoo! Common Stock for approximately 31,403,000 shares of GeoCities common stock. Additionally, the Company will convert approximately 8,894,000 GeoCities stock options into approximately 6,019,000 Yahoo! stock options. The acquisition is expected to be completed in the second quarter of 1999 and is subject to certain conditions, regulatory approval, and approval by GeoCities stockholders. The Company expects to record a one-time charge in the second quarter of 1999 relating to expenses incurred with this transaction. GeoCities' operating results for the years ended December 31, 1998, 1997, and 1996 included revenues of approximately $18.4 million, $4.6 million, and $0.3 million, respectively, and net losses of approximately $19.8 million, $8.9 million, and $3.0 million, respectively. The Company's revenues are derived principally from the sale of banner and sponsorship advertisements. The Company's standard rates for banner advertising currently range from approximately $6.00 per thousand impressions for run of network to approximately $90.00 per thousand impressions for highly targeted audiences and properties. To date, the duration of the Company's banner advertising commitments has ranged from one week to two years. Sponsorship advertising contracts have longer terms (ranging from three months to two years) than standard banner advertising contracts and also involve more integration with Yahoo! services, such as the placement of buttons that provide users with direct links to the advertiser's Web site. Advertising revenues on both banner and sponsorship contracts are recognized ratably over the period in which the advertisement is displayed, provided that no significant Company obligations remain at the end of a period and collection of the resulting receivable is probable. Company obligations typically include guarantees of minimum number of "impressions," or times that an advertisement appears in pages viewed by users of the Company's online properties. To the extent minimum guaranteed impressions are not met, the Company defers recognition of the corresponding revenues until the remaining guaranteed impression levels are achieved. The Company also earns revenue on sponsorship contracts from fees relating to the design, coordination, and integration of customers' content and links into Yahoo! online media properties. These development fees are recognized as revenue once the related activities have been performed and the customer's Web links are available on Yahoo! online media properties. A number of the Company's agreements provide that Yahoo! receive revenues from electronic commerce transactions. Currently, these revenues are recognized by the Company upon notification from the advertiser of revenues earned by Yahoo!. Revenues from barter transactions are recognized during the period in which the advertisements are displayed in Yahoo! properties. Barter transactions are recorded at the fair value of the goods or services provided or received, whichever is more readily determinable in the circumstances. To date, revenues from development fees, electronic commerce transactions, and barter transactions have each been less than 10% of net revenues. 4

In August 1996, the Company entered into agreements with Visa International Service Association ("VISA") and another party (together, the "Visa Group") to establish a limited liability company, Yahoo! Marketplace L.L.C., to develop and operate a navigational service focused on information and resources for the purchase of consumer products and services over the Internet. During July 1997, prior to the completion of significant business activities and public launch of the property, the Company and VISA entered into an agreement under which the Visa Group released the Company from certain obligations and claims. In connection with this agreement, Yahoo! issued 2,797,924 shares of Yahoo! Common Stock to the Visa Group, for which the Company recorded a one-time, non-cash, pre-tax charge of $21.2 million in the second quarter ended June 30, 1997. RESULTS OF OPERATIONS NET REVENUES. Net revenues were $203.3 million, $70.5 million , and $21.5 million for the years ended December 31, 1998, 1997, and 1996, respectively. The increases from year to year are due primarily to the increasing number of advertisers purchasing space on the Company's online media properties as well as larger and longer-term purchases by certain advertisers. Approximately 3,800 customers advertised on the Company's online media properties during 1998 as compared to approximately 2,600 and 700 in 1997 and 1996, respectively. No one customer accounted for 10% or more of net revenues during the years ended December 31, 1998 and 1997, and SOFTBANK and its related companies ("SOFTBANK") accounted for 11% of net revenues during 1996. Advertising purchases by SOFTBANK, a 30% shareholder of the Company at December 31, 1998, accounted for approximately 5% and 4% of net revenues during the years ended December 31, 1998 and 1997, respectively. Contracted prices on these orders are comparable to those given to other major customers of the Company. International revenues have accounted for less than 10% of net revenues during the years ended December 31, 1998, 1997, and 1996. Barter revenues also represented less than 10% of net revenues during those periods. There can be no assurance that customers will continue to purchase advertising on the Company's Web pages, that advertisers will not make smaller and shorter term purchases, or that market prices for Web-based advertising will not decrease due to competitive or other factors. Additionally, while the Company has experienced strong revenue growth during the last three years, management does not believe that this level of revenue growth will be sustained in future periods. COST OF REVENUES. Cost of revenues consists of the expenses associated with the production and usage of Yahoo! and the Company's other online media properties. These costs primarily consist of fees paid to third parties for content included on the Company's online media properties, Internet connection charges, amortization of purchased technology, prize awards, equipment depreciation, and compensation. Cost of revenues were $26.7 million for the year ended December 31, 1998, or 13% of net revenues, as compared to $10.9 million, or 15% of net revenues, and $4.7 million, or 22% of net revenues, for the years ended December 31, 1997 and 1996, respectively. The absolute dollar increases in cost of revenues from year to year are primarily attributable to an increase in the quantity of content available on the Company's online media properties, the increased usage of these properties, and the amortization of technology purchased in the Viaweb acquisition. The Company anticipates that its content and Internet connection expenses will increase with the quantity and quality of content available on Yahoo! online media properties, and increased usage of these properties. As measured in page views (defined as electronic page displays), the Company delivered an average of approximately 167 million page views per day in December 1998 compared with an average of approximately 65 million page views per day in December 1997 and an average of approximately 20 million page views per day in December 1996. Yahoo! Japan, an unconsolidated joint venture of the Company that began operations in April 1996, is included in these page views figures and accounted for an average of approximately 13 million per day in December 1998, an average of approximately 5 million per day in December 1997, and an average of approximately 1.4 million per day in December 1996. The Company anticipates that its content and Internet connection expenses will continue to increase in absolute 5

dollars for the foreseeable future. The Company currently anticipates cost of revenues will be in the range of 10% to 13% of net revenues for 1999, however, anticipated spending levels may vary as a result of acquisitions and future business combinations. SALES AND MARKETING. Sales and marketing expenses were $92.4 million for the year ended December 31, 1998, or 45% of net revenues. For the years ended December 31, 1997 and 1996, sales and marketing expenses were $45.8 million and $16.2 million, or 65% and 75% of net revenues, respectively. Sales and marketing expenses consist primarily of advertising and other marketing-related expenses (which include distribution costs), compensation and employee-related expenses, sales commissions, and travel costs. The year-to-year increases in absolute dollars are primarily attributable to an increase in advertising and distribution costs associated with the Company's aggressive brand-building strategy, increases in compensation expense associated with growth in its direct sales force and marketing personnel, expansion in the international subsidiaries with the addition of subsidiaries in Germany, France, and the United Kingdom during 1996, Sweden, Australia, Singapore, Korea, Denmark, and Norway during 1997, and Italy, Hong Kong, and Spain as well as Yahoo! guides in Spanish and Mandarin Chinese languages during 1998, and an increase in sales commissions associated with the increase in revenues. The Company anticipates that sales and marketing expenses in absolute dollars will increase in future periods as it continues to pursue an aggressive brand-building strategy through advertising and distribution, continues to expand its international operations, and continues to build its global direct sales organization. As a percentage of net revenues, the Company currently anticipates that sales and marketing expenses will be in the range of 40% to 43% for 1999, however, anticipated spending levels may vary as a result of acquisitions and future business combinations. PRODUCT DEVELOPMENT. Product development expenses were $22.7 million, or 11% of net revenues for the year ended December 31, 1998 compared to $12.1 million and $5.7 million, or 17% and 27% of net revenues for the years ended December 31, 1997 and 1996, respectively. Product development expenses consist primarily of employee compensation relating to developing and enhancing the features and functionality of Yahoo! online media properties. The year-to-year increases in absolute dollars are primarily attributable to increases in the number of engineers that develop and enhance Yahoo! online media properties. To date, all internal product development costs have been expensed as incurred. The Company believes that significant investments in product development are required to remain competitive. Consequently, the Company expects to incur increased product development expenditures in absolute dollars in future periods. As a percentage of net revenues, the Company currently anticipates that product development expenses will range from 10% to 12% during 1999, however, anticipated spending levels may vary as a result of acquisitions and future business combinations. GENERAL AND ADMINISTRATIVE. General and administrative expenses were $11.2 million, or 6% of net revenues for the year ended December 31, 1998 compared to $7.4 million and $5.8 million, or 10% and 27% of net revenues for the years ended December 31, 1997 and 1996, respectively. General and administrative expenses consist primarily of compensation and fees for professional services, and the year-to-year increases in absolute dollars are primarily attributable to increases in these areas. The Company believes that the absolute dollar level of general and administrative expenses will increase in future periods, as a result of an increase in personnel and increased fees for professional services. As a percentage of net revenues, the Company currently anticipates that general and administrative expenses will approximate 5% during 1999, however, anticipated spending levels may vary as a result of acquisitions and future business combinations. AMORTIZATION OF INTANGIBLES. As part of the Viaweb acquisition, the Company recorded an intangible asset related to goodwill in the amount of $24.3 million. This asset is being amortized over a seven-year period beginning in June 1998. OTHER--NON-RECURRING COSTS. During June 1998, the Company completed the acquisition of all outstanding shares of Viaweb through the issuance of 1,574,364 shares of Yahoo! Common Stock. All 6

outstanding options to purchase Viaweb common stock were converted into options to purchase 244,504 shares of Yahoo! Common Stock. During the quarter ended June 30, 1998, the Company recorded a non-recurring charge of $15.0 million for in-process research and development that had not yet reached technological feasibility and had no alternative future use. On October 20, 1998, the Company completed the acquisition of all outstanding shares, options, and warrants of Yoyodyne through the issuance of 561,244 shares of Yahoo! Common Stock and options and warrants to purchase Yahoo! Common Stock. During the quarter ended December 31, 1998, the Company recorded a one-time charge of approximately $2.1 million for expenses incurred with the transaction. During December 1998, the Company completed the acquisition of all outstanding shares of HyperParallel through the issuance of 74,856 shares of Yahoo! Common Stock and some cash. During the quarter ended December 31, 1998, the Company recorded a non-recurring charge of $2.3 million for in-process research and development that had not yet reached technological feasibility and had no alternative future use. During July 1997, the Company and VISA entered into an agreement under which the Visa Group released the Company from certain obligations and claims. In connection with this agreement, Yahoo! issued 2,797,924 shares of Yahoo! Common Stock to the Visa Group, for which the Company recorded a one-time, non-cash, pre-tax charge of $21.2 million in the second quarter ended June 30, 1997. In conjunction with the October 1997 acquisition of Four11 Corporation, the Company recorded a one-time charge of $3.9 million which consisted of investment banking fees, legal and accounting fees, redundancy costs, and certain other expenses directly related to the acquisition. INVESTMENT INCOME, NET. Investment income, net of expense, was $14.6 million for the year ended December 31, 1998 compared to $4.5 million and $4.0 million for the years ended December 31, 1997 and 1996, respectively. The increase from 1997 to 1998 is primarily attributable to a higher average investment balance, principally due to proceeds of $250.0 million received by the Company on July 14, 1998 from a private placement of shares to SOFTBANK. Investment income in future periods may fluctuate as a result of fluctuations in average cash balances maintained by the Company and changes in the market rates of its investments. MINORITY INTERESTS IN OPERATIONS OF CONSOLIDATED SUBSIDIARIES. Minority interests in operations of consolidated subsidiaries were $68,000 for the year ended December 31, 1998 compared to $727,000 and $540,000 for the years ended December 31, 1997 and 1996, respectively. The decrease from 1997 to 1998 is primarily attributable to near break-even results in the European and Korean joint ventures in the aggregate. The increase from 1996 to 1997 is primarily attributable to the staggered launch dates of the joint ventures. Yahoo! Europe operations began during the third quarter of 1996 and Yahoo! Korea operations started in the third quarter of 1997. The Company expects that minority interests in operations of consolidated subsidiaries in the aggregate will continue to fluctuate in future periods as a function of the results from consolidated subsidiaries. When, and if, the consolidated subsidiaries become profitable, the minority interests adjustment on the statement of operations will reduce the Company's net income by the minority partners' share of the subsidiaries' net income. INCOME TAXES. Yahoo! recorded an income tax provision of $17.8 million in 1998. At December 31, 1998, the Company had net operating loss carryforwards and research tax credit carryforwards, which if not utilized, will begin to expire in 2003 through 2010. Deferred tax assets totaled $152.7 million of which approximately $141 million relates to net operating loss carryforwards and tax credit carryforwards from the exercise of stock options. When recognized, the tax benefit of the loss and credit carryforwards is accounted for as a credit to additional paid-in capital rather than as a reduction of income tax expense. The Company has a valuation allowance of $135.1 million for deferred tax assets for which realization is not more-likely-than-not. The Company's 1998 estimated income tax rate was impacted during the year by the release of the prior year's valuation allowance, nondeductible acquisition-related charges, and pre-acquisition losses of companies acquired in 1998. 7

NET INCOME (LOSS). The Company recorded net income of $25.6 million or $0.11 per share diluted for the year ended December 31,1998 compared to net losses of $25.5 million and $6.4 million, or $0.15, and $0.04 per share diluted for the years ended December 31, 1997 and 1996, respectively. Excluding the effect of the non-recurring charge of $19.4 million incurred in connection with various 1998 acquisitions and the amortization of $2.9 million and $2.0 million from the purchased technology and intangible assets acquired in the purchase of Viaweb, the Company earned $49.9 million or $0.22 per share diluted for the year ended December 31, 1998. Excluding the effect of the one-time, non-cash, pre-tax charge of $21.2 million recorded for the restructuring of the Yahoo! Marketplace agreements with the Visa Group and the one-time charge of $3.9 million recorded for costs incurred for the acquisition of Four11, the Company's net loss was $0.4 million or $0.00 per share diluted for the year ended December 31, 1997. LIQUIDITY AND CAPITAL RESOURCES Yahoo! invests excess cash predominantly in debt instruments that are highly liquid, of high-quality investment grade, and predominantly have maturities of less than one year with the intent to make such funds readily available for operating purposes. At December 31, 1998, the Company had cash and cash equivalents and investments in marketable debt securities totaling $482.4 million compared to $108.0 million at December 31, 1997. For the year ended December 31, 1998, cash provided by operating activities was $110.3 million compared to cash provided by operating activities of $0.5 million and cash used for operating activities of $2.4 million for the years ended December 31, 1997 and 1996, respectively. For the year ended December 31, 1998, cash provided by operating activities of $110.3 million was primarily due to earnings, before non-recurring charges of $17.3 million and depreciation and amortization of $10.2 million, increases in deferred revenue (due to invoicing and cash receipts in excess of revenue) and accrued liabilities, and tax benefits from stock option plans. The increase in deferred revenue relates principally to overall significant growth in revenue and increases in advanced payments on several new and relatively longer sponsorship agreements. For the year ended December 31, 1997, cash provided by operating activities of $0.5 million was primarily due to increases in accrued liabilities and deferred revenue, substantially offset by increases in prepaid expenses and other assets, which resulted primarily from a $5.0 million one-time non-refundable license payment to Netscape under the Netscape Guide by Yahoo! agreement and a $2.9 million payment to Netscape under the international Netscape Net Search program agreement. For the year ended December 31, 1996, cash used by operating activities was $2.4 million. Cash used in investing activities was $329.9 million for the year ended December 31, 1998. Purchases (net of sales and maturities) of investments in marketable securities and other assets during the period were $312.8 million and capital expenditures totaled $11.9 million. Capital expenditures have generally been comprised of purchases of computer hardware and software as well as leasehold improvements related to leased facilities, and are expected to increase in future periods. Cash provided by investing activities was $19.6 million for the year ended December 31, 1997. Sales and maturities (net of purchases) of investments in marketable securities during the period were $27.9 million and capital expenditures totaled $6.7 million. Cash used in investing activities was $76.2 million for the year ended December 31, 1996. Purchases (net of sales and maturities) of investments in marketable securities and other assets during the period were $72.0 million and capital expenditures totaled $3.4 million. For the year ended December 31, 1998, cash provided by financing activities of $281.3 million was due primarily to the issuance of Common Stock to SOFTBANK in the amount of $250.0 million during July 1998 and the issuance of Common Stock pursuant to the exercise of stock options. For the year ended December 31, 1997, cash provided by financing activities of $9.6 million was due primarily to the issuance of Common Stock pursuant to the exercise of stock options. For the year ended December 31, 8

1996, cash provided by financing activities of $107.2 million was primarily due to the March 1996 issuance of 5.1 million shares of Convertible Series C Preferred Stock for aggregate proceeds of $63.8 million, the April 1996 initial public offering of 17.9 million shares of Common Stock for net proceeds of $35.1 million, and other issuances of Common Stock. The Company currently has no material commitments other than those under operating lease agreements. The Company has experienced a substantial increase in its capital expenditures and operating lease arrangements since its inception, which is consistent with increased staffing, and anticipates that this will continue in the future. Additionally, the Company will continue to evaluate possible acquisitions of, or investments in businesses, products, and technologies that are complementary to those of the Company, which may require the use of cash. Management believes existing cash and investments will be sufficient to meet the Company's operating requirements for at least the next twelve months; however, the Company may sell additional equity or debt securities or obtain credit facilities to further enhance its liquidity position. The sale of additional securities could result in additional dilution to the Company's shareholders. YEAR 2000 IMPLICATIONS Many currently installed computer systems and software products are coded to accept only two-digit entries in the date code field and cannot distinguish 21st century dates from 20th century dates. These date code fields will need to distinguish 21st century dates from 20th century dates and, as a result, many companies' software and computer systems may need to be upgraded or replaced in order to comply with such "Year 2000" requirements. The Company is in the process of assessing the Year 2000 issue and expects to complete the program by the spring of 1999. The Company has not incurred material costs to date in this process, and currently does not believe that the cost of additional actions will have a material effect on its results of operations or financial condition. Although Yahoo! currently believes that its systems are Year 2000 compliant in all material respects, the current systems and products may contain undetected errors or defects with Year 2000 date functions that may result in material costs. Although Yahoo! is not aware of any material operational issues or costs associated with preparing its internal systems for the Year 2000, the Company may experience serious unanticipated negative consequences (such as significant downtime for one or more Yahoo! Media properties) or material costs caused by undetected errors or defects in the technology used in its internal systems. In addition, the Company utilizes third-party equipment, software and content, including non-information technology systems ("non-IT systems"), such as its security system, building equipment, and non-IT systems embedded microcontrollers that may not be Year 2000 compliant. The Company is in the process of developing a plan to assess whether these third parties are adequately addressing the Year 2000 issue and whether any of its non-IT systems have material Year 2000 compliance problems. Failure of such third-party equipment, software, or content to operate properly with regard to the year 2000 and thereafter could require the Company to incur unanticipated expenses to remedy any problems, which could have a material adverse effect on its business, results of operations, and financial condition. Yahoo! is in the process of fully developing a comprehensive contingency plan to address situations that may result if it is unable to achieve Year 2000 readiness of its critical operations. Finally, the Company is also subject to external forces that might generally affect industry and commerce, such as utility or transportation company Year 2000 compliance failures and related service interruptions. Furthermore, the purchasing patterns of advertisers may be affected by Year 2000 issues as companies expend significant resources to correct their current systems for Year 2000 compliance. The Company does not currently have any information about the Year 2000 status of its advertising customers. However, these expenditures may result in reduced funds available for Web advertising or sponsorship of Web services, which could have a material adverse effect on the Company's business, results of operations, and financial condition. 9

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The Company is exposed to the impact of interest rate changes, foreign currency fluctuations, and change in the market values of its investments. INTEREST RATE RISK. The Company's exposure to market rate risk for changes in interest rates relates primarily to the Company's investment portfolio. The Company has not used derivative financial instruments in its investment portfolio. The Company invests its excess cash in debt instruments of the U.S. Government and its agencies, and in high-quality corporate issuers and, by policy, limits the amount of credit exposure to any one issuer. The Company protects and preserves its invested funds by limiting default, market and reinvestment risk. Investments in both fixed rate and floating rate interest earning instruments carries 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, the Company's future investment income may fall short of expectations due to changes in interest rates or the Company may suffer losses in principal if forced to sell securities which have declined in market value due to changes in interest rates. FOREIGN CURRENCY RISK. International revenues from the Company's foreign subsidiaries were less than 10% of total revenues. International sales are made mostly from the Company's foreign sales subsidiaries in their respective countries and are typically denominated in the local currency of each country. These subsidiaries also incur most of their expenses in the local currency. Accordingly, all foreign subsidiaries use the local currency as their functional currency. The Company's international business is subject to risks typical of an international business, including, but not limited to differing economic conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate volatility. Accordingly, the Company's future results could be materially adversely impacted by changes in these or other factors. The Company's exposure to foreign exchange rate fluctuations arises in part from intercompany accounts in which costs incurred in the United States are charged to the Company's foreign sales subsidiaries. These intercompany accounts are typically denominated in the functional currency of the foreign subsidiary in order to centralize foreign exchange risk with the parent company in the United States. The Company is also exposed to foreign exchange rate fluctuations as the financial results of foreign subsidiaries are translated into U.S. dollars in consolidation. As exchange rates vary, these results, when translated, may vary from expectations and adversely impact overall expected profitability. The effect of foreign exchange rate fluctuations on the Company in 1998 was not material. INVESTMENT RISK. The Company invests in equity instruments of privately-held, information technology companies for business and strategic purposes. These investments are included in other long-term assets and are accounted for under the cost method when ownership is less than 20%. For these non-quoted investments, the Company's policy is to regularly review the assumptions underlying the operating performance and cash flow forecasts in assessing the carrying values. The Company identifies and records impairment losses on long-lived assets when events and circumstances indicate that such assets might be impaired. To date, no such impairment has been recorded. During 1998, certain of these investments in privately-held companies became marketable equity securities when the investees completed initial public offerings. Such investments, which are in the Internet industry, are subject to significant fluctuations in fair market value due to the volatility of the stock market, and are recorded as long-term investments. 10

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 1 THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES THE COMPANY. Yahoo! Inc. ("Yahoo!" or the "Company") is a global Internet media company that offers a branded network of comprehensive information, communication, and shopping services to millions of users daily. The Company was incorporated in California on March 5, 1995 and commenced operations on that date. The Company conducts its business within one industry segment. On October 20, 1998 and 1997, the Company consummated its acquisitions of Yoyodyne Entertainment, Inc. ("Yoyodyne") and Four11 Corporation ("Four11"), respectively, upon which Yoyodyne's and Four11's shareholders exchanged all of their shares for shares of the Company's Common Stock in business combinations that were accounted for as pooling of interests. The consolidated financial statements for the three years ended December 31, 1998 and the accompanying notes reflect the Company's financial position and the results of operations as if Yoyodyne and Four11 were wholly-owned subsidiaries of the Company since inception. Components of the consolidated results of operations of Yahoo! and of Four11 and Yoyodyne prior to their acquisitions by Yahoo! are as follows (in thousands): YEAR ENDED DECEMBER 31, ------------------------------- 1998 1997 1996 --------- --------- --------- NET REVENUES Yahoo!....................................... $ 201,446 $ 65,460 $ 19,073 Four11....................................... -- 1,951 624 Yoyodyne..................................... 1,824 3,039 1,793 --------- --------- --------- $ 203,270 $ 70,450 $ 21,490 --------- --------- --------- --------- --------- --------- NET INCOME (LOSS) Yahoo!....................................... $ 30,216 $ (19,973) $ (2,334) Four11....................................... -- (2,914) (1,951) Yoyodyne..................................... (4,628) (2,633) (2,142) --------- --------- --------- $ 25,588 $ (25,520) $ (6,427) --------- --------- --------- --------- --------- --------- STOCK SPLITS. During July 1998, the Company's Board of Directors approved a two-for-one Common Stock split. Shareholders of record on July 17, 1998 (the record date) received one additional share for every share held on that date. The shares were distributed on July 31, 1998 and the stock split was effective on August 3, 1998. During January 1999, the Company's Board of Directors approved a two-for-one Common Stock split. Shareholders of record on January 22, 1999 (the record date) received one additional share for every share held on that date. The shares were distributed on February 5, 1999 and the stock split was effective on February 8, 1999. All share numbers in these consolidated financial statements and notes thereto for all periods presented have been adjusted to reflect the two-for-one common stock splits. PRINCIPLES OF CONSOLIDATION. The consolidated financial statements include the accounts of Yahoo! Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The equity and net loss attributable to the minority shareholder interests that related to the Company's subsidiaries, are shown separately in the consolidated balance sheets and consolidated statements of operations, respectively. Losses in excess of the minority interest equity would be charged against the Company. Investments in entities owned 20% or more but less than 17

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1 THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) majority owned and not otherwise controlled by the Company are accounted for under the equity method. RECLASSIFICATIONS. Certain prior years' balances have been reclassified to conform with the current year's presentation. REVENUE RECOGNITION. The Company's revenues are derived principally from the sale of banner and sponsorship advertisements. The Company's standard rates for banner advertising currently range from approximately $6.00 per thousand impressions for run of network to approximately $90.00 per thousand impressions for highly targeted audiences and properties. To date, the duration of the Company's banner advertising commitments has ranged from one week to two years. Sponsorship advertising contracts have longer terms (ranging from three months to two years) than standard banner advertising contracts and also involve more integration with Yahoo! services, such as the placement of buttons that provide users with direct links to the advertiser's Web site. Advertising revenues on both banner and sponsorship contracts are recognized ratably over the period in which the advertisement is displayed, provided that no significant Company obligations remain at the end of a period and collection of the resulting receivable is probable. Company obligations typically include guarantees of minimum number of "impressions," or times that an advertisement appears in pages viewed by users of the Company's online properties. To the extent minimum guaranteed impressions are not met, the Company defers recognition of the corresponding revenues until the remaining guaranteed impression levels are achieved. The Company also earns revenue on sponsorship contracts from fees relating to the design, coordination, and integration of customers' content and links into Yahoo! online media properties. These development fees are recognized as revenue once the related activities have been performed and the customer's Web links are available on Yahoo! online media properties. A number of the Company's agreements provide that Yahoo! receive revenues from electronic commerce transactions. Currently, these revenues are recognized by the Company upon notification from the advertiser of revenues earned by Yahoo!. Revenues from barter transactions are recognized during the period in which the advertisements are displayed in Yahoo! properties. Barter transactions are recorded at the fair value of the goods or services provided or received, whichever is more readily determinable in the circumstances. To date, revenues from development fees, electronic commerce transactions, and barter transactions have each been less than 10% of net revenues. No one customer accounted for 10% or more of net revenues during 1998 and 1997, and SOFTBANK and its related companies ("SOFTBANK"), a holder of approximately 30% of the Company's Common Stock at December 31, 1998, accounted for 11% of net revenues during 1996 (see Note 4). Deferred revenue is primarily comprised of billings in excess of recognized revenue relating to advertising contracts and payments received pursuant to sponsorship advertising contracts in advance of revenue recognition. PRODUCT DEVELOPMENT. Costs incurred in the classification and organization of listings within Yahoo! properties and the development of new products and enhancements to existing products are charged to expense as incurred. Material software development costs subsequent to the establishment of technological feasibility are capitalized. Based upon the Company's product development process, technological feasibility is established upon completion of a working model. Costs incurred by the 18

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1 THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Company between completion of the working model and the point at which the product is ready for general release have been insignificant. ADVERTISING COSTS. Advertising production costs are recorded as expense the first time an advertisement appears. All other advertising costs are expensed as incurred. The Company does not incur any direct-response advertising costs. Advertising expense totaled approximately $32.7 million, $10.9 million, and $4.2 million for 1998, 1997, and 1996, respectively. BENEFIT PLAN. The Company maintains a 401(k) Profit Sharing Plan (the "Plan") for its full-time employees. Each participant in the Plan may elect to contribute from 1% to 17% of his or her annual compensation to the Plan. The Company matches employee contributions at a rate of 25%. Employee contributions are fully vested, whereas vesting in matching Company contributions occurs at a rate of 33.3% per year of employment. During 1998, 1997 and 1996, the Company's contributions amounted to $584,000, $263,000, and $81,000, respectively. CASH AND CASH EQUIVALENTS, SHORT AND LONG-TERM INVESTMENTS. The Company invests its excess cash in debt instruments of the U.S. Government and its agencies, and in high-quality corporate issuers. All highly liquid instruments with an original maturity of three months or less are considered cash equivalents, those with original maturities greater than three months and current maturities less than twelve months from the balance sheet date are considered short-term investments, and those with maturities greater than twelve months from the balance sheet date are considered long-term investments. The Company's marketable securities are classified as available-for-sale as of the balance sheet date and are reported at fair value, with unrealized gains and losses, net of tax, recorded in shareholders' equity. Realized gains or losses and permanent declines in value, if any, on available-for-sale securities will be reported in other income or expense as incurred. As of December 31, 1998, the Company recorded net unrealized gains, net of income taxes, of $21.8 million. The Company invests in equity instruments of privately-held, information technology companies for business and strategic purposes. These investments are included in other long-term assets and are accounted for under the cost method when ownership is less than 20%. For these non-quoted investments, the Company's policy is to regularly review the assumptions underlying the operating performance and cash flow forecasts in assessing the carrying values. The Company identifies and records impairment losses on long-lived assets when events and circumstances indicate that such assets might be impaired. To date, no such impairment has been recorded. During 1998, certain of these investments in privately-held companies became marketable equity securities when the investees completed initial public offerings. Such investments, which are in the Internet industry, are subject to significant fluctuations in fair market value due to the volatility of the stock market, and are recorded as long-term investments. CONCENTRATION OF CREDIT RISK. Financial instruments that potentially subject the Company to significant concentration of credit risk consist primarily of cash, cash equivalents, short and long-term investments, and accounts receivable. Substantially all of the Company's cash, cash equivalents, and short and long-term investments are managed by four financial institutions. Accounts receivable are typically unsecured and are derived from revenues earned from customers primarily located in the United States. The Company performs ongoing credit evaluations of its customers and maintains 19

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1 THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) reserves for potential credit losses; historically, such losses have been within management's expectations. At December 31, 1998 and 1997, no one customer accounted for 10% or more of the accounts receivable balance. DEPRECIATION AND AMORTIZATION. Property and equipment, including leasehold improvements, are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets, generally two to five years. Goodwill and other intangible assets are included in other assets and are carried at cost less accumulated amortization, which is being provided on a straight-line basis over the economic lives of the respective assets, generally three to seven years. The Company periodically evaluates the recoverability of its long-lived assets based on expected undiscounted cash flows and recognizes impairments, if any, based on expected discounted future cash flows. INCOME TAXES. Income taxes are computed using the asset and liability method. Under the asset and liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted tax rates and laws. A valuation allowance is provided for the amount of deferred tax assets that, based on available evidence, are not expected to be realized. STOCK-BASED COMPENSATION. The Company accounts for stock-based employee compensation arrangements in accordance with the provisions of Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees," and complies with the disclosure provisions of Statement of Financial Accounting Standards ("SFAS') No. 123, "Accounting for Stock-Based Compensation." Under APB 25, compensation cost is recognized over the vesting period based on the difference, if any, on the date of grant between the fair value of the Company's stock and the amount an employee must pay to acquire the stock. FOREIGN CURRENCY AND INTERNATIONAL OPERATIONS. The functional currency of the Company's international subsidiaries is the local currency. The financial statements of these subsidiaries are translated to United States dollars using year-end rates of exchange for assets and liabilities, and average rates of exchange for the year for revenues, costs, and expenses. Translation gains (losses), which are deferred and accumulated as a component of shareholders' equity, were $288,000, ($380,000), and ($63,000) for 1998, 1997, and 1996, respectively. Net gains and losses resulting from foreign exchange transactions are included in the consolidated statements of operations and were not significant during the periods presented. International revenues have accounted for less than 10% of net revenues in the years ended December 31, 1998, 1997, and 1996. International assets were not significant at December 31, 1998, 1997, or 1996. BASIC AND DILUTED NET INCOME (LOSS) PER SHARE. Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of the incremental common shares issuable upon conversion of convertible preferred stock (using the if-converted method) and shares issuable upon the exercise of stock options and warrants (using the treasury stock method). For 1998, common equivalent shares primarily related to shares issuable upon the exercise of stock options and approximated 40.0 million shares. Common equivalent shares in 1997 and 1996 were excluded from the computation as their effect was anti-dilutive. 20

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 1 THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) USE OF ESTIMATES. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. COMPREHENSIVE INCOME. In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS 130, "Reporting Comprehensive Income," which was adopted by the Company in the first quarter of fiscal 1998. SFAS 130 establishes standards for reporting comprehensive income and its components in a financial statement. Comprehensive income as defined includes all changes in equity (net assets) during a period from non-owner sources. Examples of items to be included in comprehensive income, which are excluded from net income, include foreign currency translation adjustments and unrealized gains and losses on available-for-sale securities. Accumulated other comprehensive income, as presented on the accompanying consolidated balance sheets, consists of the net unrealized gains on available-for-sale securities, net of tax and the cumulative translation adjustment. RECENT ACCOUNTING PRONOUNCEMENTS. In June 1998, the FASB issued SFAS 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS 133 establishes methods of accounting for derivative financial instruments and hedging activities related to those instruments as well as other hedging activities, and is effective for fiscal years beginning after June 15, 1999. The Company is currently determining the additional disclosures, if any, that may be required under this pronouncement. In March 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use." This standard requires companies to capitalize qualifying computer software costs which are incurred during the application development stage and amortize them over the software's estimated useful life. SOP 98-1 is effective for fiscal years beginning after December 15, 1998. The Company is currently evaluating the impact of SOP 98-1 on its financial statements and related disclosures. 21

At December 31, 1997, the fair value of the investments approximated cost. NOTE 4 RELATED PARTY TRANSACTIONS During 1998, 1997 and 1996, the Company recognized net revenues of approximately $10.3 million, $3.1 million, and $2.4 million, respectively, on advertising contracts and publication, development, and licensing arrangements with SOFTBANK and its related companies (such as E*Trade Group, Inc., Kingston Technology Company, and E-Loan, Inc.), a holder of approximately 30% of the Company's Common Stock at December 31, 1998. Prices on these contracts were comparable to those given to other similar customers of the Company. Additionally, three SOFTBANK-related companies provided Internet access and sales and marketing-related services for fees of approximately $3.1 million, $3.2 million, and $2.3 million during 1998, 1997, and 1996, respectively. Sequoia Capital, a holder of approximately 3% of the Company's Common Stock at December 31, 1998, was also an investor in one of these SOFTBANK-related companies. NOTE 5 ACQUISITIONS ACQUISITION OF NETCONTROLS. On July 31, 1997, the Company entered into a stock purchase agreement to acquire all of the outstanding capital stock of NetControls, Inc. for 148,668 shares of the Company's Common Stock. The acquisition was recorded as a purchase for accounting purposes and the majority of the purchase price of approximately $1.4 million is being amortized over the three-year estimated useful life of the technology acquired. Upon acquisition, the historical financial results of NetControls, Inc. were de minimis. ACQUISITION OF FOUR11. On October 20, 1997, the Company completed the acquisition of Four11 Corporation, a privately-held online communications and Internet directory company. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 6,022,880 shares of Yahoo! Common Stock for all of Four11's outstanding shares and assumed 593,344 options and warrants to purchase Yahoo! Common Stock. All outstanding Four11 preferred shares were converted into Four11 common stock immediately prior to the acquisition. During the quarter ended December 31, 1997, the Company recorded a one-time charge of $3.9 million for acquisition-related costs. These costs consisted of investment banking fees, legal and accounting fees, redundancy costs, and certain other expenses directly related to the acquisition. 23

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 5 ACQUISITIONS (CONTINUED) ACQUISITION OF VIAWEB INC. On June 10, 1998, the Company completed the acquisition of all outstanding shares of Viaweb, a provider of software and services for hosting online stores, through the issuance of 1,574,364 shares of Yahoo! Common Stock. All outstanding options to purchase Viaweb common stock were converted into options to purchase 244,504 shares of Yahoo! Common Stock. The acquisition was accounted for as a purchase in accordance with the provisions of APB 16. Under the purchase method of accounting, the purchase price is allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of the acquisition. Results of operations for Viaweb have been included with those of the Company for periods subsequent to the date of acquisition. The total purchase price of the acquisition was $48.6 million including acquisition expenses of $1.8 million. The purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values as determined by the Company and pursuant to discussions with the Staff of the Securities and Exchange Commission (the "Staff") as follows (in thousands): In-process research and development................................ $ 15,000 Purchased technology............................................... 15,000 Goodwill........................................................... 24,332 Tangible assets acquired........................................... 571 Liabilities assumed................................................ (344) Deferred tax liability............................................. (6,000) --------- $ 48,559 --------- --------- Among the factors considered in discussions with the Staff in determining the amount of the allocation of the purchase price to in-process research and development were various factors such as estimating the stage of development of each in-process research and development project at the date of acquisition, estimating cash flows resulting from the expected revenues generated from such projects, and discounting the net cash flows, in addition to other assumptions. The remaining identified intangibles, including the value of purchased technology and other intangibles will be amortized on a straight-line basis over three and seven years, respectively. Amortization expense of purchased technology and other intangible assets was $2.9 million and $2.0 million, respectively, for the year ended December 31, 1998. A deferred tax liability has been recognized for the difference between the assigned values for book purposes and the tax bases of assets in accordance with the provisions of SFAS 109. In addition, other factors were considered in discussions with the Staff in determining the value assigned to purchased in-process technology such as research projects in areas supporting the online store technology (including significant enhancement to the ability of the product to support multiple users and multiple servers), developing functionality to support the ability to process credit card orders, and enhancing the product's user interface by developing functionality that would allow the product to be used outside of the United States. If none of these projects is successfully developed, the Company's sales and profitability may be adversely affected in future periods. Additionally, the failure of any particular individual project in process could impair the value of other intangible assets acquired. The Company began to benefit from the purchased in-process technology in late 1998. Yahoo! is continuing the development efforts associated with online store technology, credit card processing and to a lesser extent international functionality. The development efforts with respect to 24

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 5 ACQUISITIONS (CONTINUED) the online store technology and credit card processing are on schedule with Yahoo!'s original assumptions with various features having been introduced as of December 31, 1998. Given the complexities of completing the international functionality, Yahoo! continues to make progress in the development of these features and now expects to be substantially complete by the end of June 1999. ACQUISITION OF WEBCAL CORPORATION. On July 17, 1998, the Company completed the acquisition of WebCal Corporation ("WebCal"), a privately-held developer and marketer of Web-based calendaring and scheduling products, and publisher of EventCal, a comprehensive database of world-wide public events. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 541,908 shares of Yahoo! Common Stock for all of WebCal's outstanding shares. The historical operations of WebCal are not material to the Company's financial position or results of operations, therefore, prior period financial statements have not been restated for this acquisition. WebCal's accumulated deficit on July 17, 1998 was $1.1 million. Net revenues and pre-tax net loss for WebCal in 1998 through the date of the acquisition approximated $2,000 and $847,000, respectively. ACQUISITION OF YOYODYNE ENTERTAINMENT, INC. On October 20, 1998, the Company acquired Yoyodyne Entertainment, Inc., a privately-held, direct marketing services company. Under the terms of the acquisition, which was accounted for as a pooling of interests, the Company exchanged 561,244 shares of Yahoo! Common Stock and options and warrants to purchase Yahoo! Common Stock for all of Yoyodyne's outstanding shares, options, and warrants. The consolidated financial statements for the three years ended December 31, 1998 and the accompanying notes reflect the Company's financial position and the results of operations as if Yoyodyne was a wholly-owned subsidiary of the Company since inception. During October 1998, the Company recorded a one-time charge of $2.1 million for acquisition-related costs. These costs consisted of broker fees, legal and accounting fees, and certain other expenses directly related to the acquisition. ACQUISITION OF HYPERPARALLEL, INC. On December 17, 1998, the Company completed the acquisition of all of the outstanding shares of HyperParallel, Inc. ("HyperParallel"), a company specializing in data analysis, through the issuance of 74,856 shares of Yahoo! Common Stock and approximately $700,000 of cash totaling $8.1 million including acquisition costs. The acquisition was accounted for as a purchase in accordance with APB 16. Under the purchase method of accounting, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of the acquisition. Results of operations for HyperParallel have been included with those of the Company for periods subsequent to the acquisition. Approximately $2.3 million of the total purchase price was allocated to in-process research and development. This amount was developed by estimating the stage of development of each in-process research and development project at the date of the acquisition, estimating incremental cash flows generated from such projects, and discounting the net cash flows back to their present value using a discount rate of 35%, which represents a premium to the Company's cost of capital to take into account the uncertainty surrounding the successful development of the purchased in-process technology. The projections were based on management's estimates of market size and growth, expected trends in advertising and technology, expected research and development and selling and general administrative expenditures, and the expected timing of new product introductions. Approximately $1.2 million of the total purchase price was allocated to existing technology which is being amortized over 3 years. The value of the existing technology was developed based on similar assumptions using a discount rate of 25%. The projections used in developing the values should not be considered an accurate predictor of 25

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 5 ACQUISITIONS (CONTINUED) future performance for several reasons, including the consideration of many factors outside the control of the Company. The remaining purchase price of approximately $4.6 million was allocated to goodwill which is being amortized over 7 years. Tangible assets acquired and liabilities assumed were not material to the Company's financial statements. The value assigned to purchased in-process technology was determined by identifying three research projects in-progress as of the acquisition date. These three research projects in-progress focus on technologies surrounding search tools. Two of the application oriented development projects were 70% and 20% complete as of the acquisition date. These projects are expected to be completed in the first and fourth quarters, respectively, of 1999. The remaining project relates to the next release of the current search tool which was approximately 20% complete as of the acquisition date and is expected to be completed in the fourth quarter of 1999. Future research and development costs to be incurred on the individual in-process projects are not expected to be material to Yahoo!'s financial position or results of operations. In addition, if none of these projects were successfully developed, Yahoo!'s revenues and profitability would not be materially adversely affected. UNAUDITED PRO FORMA DISCLOSURES OF SIGNIFICANT ACQUISITIONS. The following unaudited pro forma consolidated results of operations give effect to the acquisitions of Viaweb and HyperParallel as if they occurred as of the beginning of the period (in thousands, except per share data): YEAR ENDED DECEMBER 31, -------------------- 1998 1997 --------- --------- Net revenues............................................ $ 204,136 $ 71,392 Net income (loss)....................................... $ 22,290 $ (31,866) Net income (loss) per share--basic...................... $ 0.12 $ (0.18) Net income (loss) per share--diluted.................... $ 0.10 $ (0.18) Shares used in per share calculation--basic............. 184,835 175,929 Shares used in per share calculation--diluted........... 224,983 175,929 NOTE 6 JOINT VENTURES YAHOO! JAPAN. During April 1996, the Company signed a joint venture agreement with SOFTBANK whereby Yahoo! Japan Corporation was formed to establish and manage in Japan a Japanese version of the Yahoo! Internet Guide, develop related Japanese online navigational services, and conduct other related business. The Company's ownership interest in the joint venture upon inception was 40%. During November 1997, Yahoo! Japan Corporation completed its initial public offering, issuing 975 previously unissued shares and raising total proceeds of approximately $5.5 million. Accordingly, the Company increased its investment by $1.7 million, recorded as additional paid-in capital, to reflect the increase in the Company's share of Yahoo! Japan Corporation's net assets. The investment is being accounted for using the equity method and the Company's share of net income, to date, has been immaterial. At December 31, 1998, the carrying value of the investment was $2.9 million and is recorded in other assets. However, the fair value of the Company's 34% ownership in Yahoo! Japan, based on the quoted trading price, was approximately $170 million at December 31, 1998. YAHOO! EUROPE. On November 1, 1996, the Company signed a joint venture agreement with a subsidiary of SOFTBANK whereby separate companies were formed in Germany, the United Kingdom, 26

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 6 JOINT VENTURES (CONTINUED) and France ("Yahoo! Europe") to establish and manage versions of the Yahoo! Internet Guide for those countries, develop related online navigational services, and conduct other related business. The parties have invested a total of $6.0 million in proportion to their respective equity interests as of December 31, 1998. The Company has a majority share of approximately 70% in each of the Yahoo! Europe entities, and therefore, has consolidated their financial results. During 1998, 1997, and 1996, Yahoo! Europe incurred losses from operations of $409,000, $1,807,000 and $842,000, respectively. SOFTBANK's interest in the net assets of Yahoo! Europe at December 31, 1998 and 1997, as represented by the minority interest on the balance sheet, was $883,000 and $405,000, respectively. YAHOO! KOREA. During August 1997, the Company signed a joint venture agreement with SOFTBANK and other SOFTBANK affiliate companies whereby Yahoo! Korea was formed to develop and operate a Korean version of the Yahoo! Internet Guide, develop related Korean online navigational services, and conduct other related business. The parties have invested a total of $1.0 million in proportion to their respective equity interests. The Company has a majority share of approximately 60% in the joint venture, and therefore, has consolidated the financial results, which have been insignificant to date. SOFTBANK's interest in the net assets of Yahoo! Korea at December 31, 1998 and 1997, as represented by the minority interest on the balance sheet, was $365,000 and $311,000, respectively. YAHOO! MARKETPLACE. On August 26, 1996, Yahoo! entered into agreements with Visa International Service Association ("VISA") and another party (together, the "Visa Group") to establish a limited liability company, Yahoo! Marketplace L.L.C., to develop and operate a navigational service focused on information and resources for the purchase of consumer products and services over the Internet. Yahoo!'s principal obligations included a commitment to provide operating contributions to support implementation of the service including its look and feel, development of its software, hiring of its management, promotion of the service, promotion of VISA, a nonexclusive license to Yahoo! Marketplace to use the Yahoo! brand and search tools, and an agreement that Yahoo! Marketplace would be used exclusively for the activities defined in the operating agreement. VISA's key obligations included a commitment to provide operating contributions including encouraging VISA member banks to participate and utilize the services of Yahoo! Marketplace, assistance in implementing systems to process payments, other marketing assistance activities, providing non-exclusive rights to utilization of the VISA brand, and an agreement not to compete for 18 months by entering into a similar arrangement with a Yahoo! competitor. As of December 31, 1996, the parties had invested a total of $1.0 million. At December 31, 1996, Yahoo! owned approximately 55% of the equity interest in Yahoo! Marketplace. Yahoo! Marketplace incurred start-up losses of $246,000 in 1997 and $637,000 in 1996. During May 1997, Yahoo! received a letter from VISA formally expressing its concerns with respect to breach of contract, Yahoo! support obligations, and exclusivity. In June 1997, Yahoo! conducted numerous discussions concerning settlement of these obligations and claims and proposed a settlement with the Visa Group which was signed in July 1997, prior to the completion of significant business activities and public launch of the property. In connection with this settlement, Yahoo! issued 2,797,924 shares of Yahoo! Common Stock to the Visa Group, for which Yahoo! recorded a one-time, non-cash, pre-tax charge of $21.2 million in the second quarter ended June 30, 1997. The settlement ultimately released Yahoo! from all of its obligations described above. The agreement settled all disputes and claims arising among the parties with respect to the interpretation of and the parties' respective performance under the agreements and released the parties from further liability. It also 27

YAHOO! INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) NOTE 6 JOINT VENTURES (CONTINUED) released Yahoo! from any other further damage claims by VISA for non-performance. Yahoo! also forfeited its non-compete commitment from VISA. No portions of these agreements continued in effect subsequent to the settlement. NOTE 7 SHAREHOLDERS' EQUITY COMMON STOCK. On April 11, 1996, the Company completed its initial public offering of 17.9 million shares of its Common Stock. Net proceeds to the Company aggregated $35.1 million. As of the closing date of the offering, all of the Convertible Preferred Stock outstanding was converted into an aggregate of approximately 77 million shares of Common Stock. On July 14, 1998, the Company received proceeds of $250.0 million in exchange for 5,453,760 newly issued shares of Yahoo! Common Stock through a private placement with SOFTBANK. The shares purchased by SOFTBANK are subject to a pre-existing agreement, entered into in 1996, that prohibits SOFTBANK from purchasing additional shares of the Company's capital stock if such purchase would result in SOFTBANK owning more than 35% of the Company's capital stock (assuming the exercise of all outstanding options and warrants to purchase capital stock). STOCK OPTION PLANS. Pursuant to the consummation of the acquisitions of Viaweb Inc. and Yoyodyne Entertainment, Inc. during 1998, the Company assumed the Viaweb 1997 Stock Option Plan (the "Viaweb Plan") and the 1996 Yoyodyne Stock Option Plan (the "Yoyodyne Plan"), respectively. As of December 31, 1998, the Company had five stock-based compensation plans which are described below. The 1995 Stock Plan (the "Stock Plan"), the 1995 Four11 Stock Option Plan (the "Four11 Plan"), the Viaweb Plan, and the Yoyodyne Plan (collectively the "Plans") allow for the issuance of incentive stock options, non-qualified stock options, and stock purchase rights to purchase a maximum of 87.6 million shares of the Company's Common Stock. Under the Plans, incentive stock options may be granted to employees, directors, and officers of the Company and non-qualified stock options and stock purchase rights may be granted to consultants, employees, directors, and officers of the Company. Options granted under the Plans are for periods not to exceed ten years, and must be issued at prices not less than 100% and 85%, for incentive and nonqualified stock options, respectively, of the fair market value of the stock on the date of grant as determined by the Board of Directors. Options granted to shareholders who own greater than 10% of the outstanding stock are for periods not to exceed five years and must be issued at prices not less than 110% of the fair market value of the stock on the date of grant as determined by the Board of Directors. Options granted under the Stock Plan and the Four11 Plan generally vest 25% after the first year of service and ratably each month over the remaining thirty-six month period. Options granted under the Viaweb Plan generally vest 25% on each anniversary over four years. Options granted under the Yoyodyne Plan have various vesting periods that do not exceed thirty-six months. Options issued under the Four11 Plan may be exercised prior to vesting and are subject to repurchase in the event of a voluntary termination, at the original purchase price. At December 31, 1998, shares subject to repurchase under the provisions of the Four11 Plan were insignificant. The 1996 Directors' Stock Option Plan (the "Directors' Plan") provides for the issuance of up to 1.2 million non-statutory stock options to non-employee directors of the Company. Each person who becomes a non-employee director of the Company after the date of the Company's initial public offering will automatically be granted a non-statutory option (the "First Option") to purchase 240,000 28

Thereafter, each director of the Company will be granted an annual option (the "Annual Option") to purchase 30,000 shares of Common Stock. Options under the Directors' Plan will be granted at the fair market value of the stock on the date of grant as determined by the Board of Directors and will vest in equal monthly installments over four years, in the case of the First Option, or at the end of four years in the case of the Annual Option. Options granted under the Directors' Plan are for periods not to exceed 10 years.

Approximately $1,017,000 remains to be amortized over the remaining vesting periods of the options. EMPLOYEE STOCK PURCHASE PLAN. Effective March 6, 1996, the Company's Board of Directors adopted the Employee Stock Purchase Plan (the "Purchase Plan"), which provides for the issuance of a maximum of 1,800,000 shares of Common Stock. Eligible employees can have up to 15% of their earnings withheld, up to certain maximums, to be used to purchase shares of the Company's Common Stock on every December 31(st) and June 30(th). The price of the Common Stock purchased under the Purchase Plan will be equal to 85% of the lower of the fair market value of the Common Stock on the commencement date of each six-month offering period or the specified purchase date. During 1998, 126,000 shares were purchased at prices from $14.72 to $36.10 per share. During 1997, 537,000 shares were purchased at prices from $1.85 to $4.83 per share.

Subsequent to the offering, the fair value was determined using the Black-Scholes model. The weighted average fair market value of an option granted during 1998, 1997, and 1996 was $26.53, $4.34, and $0.79, respectively. Except for the volatility assumption which was only used under the Black-Scholes model, the following range of assumptions was used to perform the calculations: expected life of 36 months in 1998 and 1997, and 30 months in 1996; risk-free interest rate ranges of 4.2% to 5.6% during 1998, 5.6% to 6.6% during 1997, and 5.1% to 6.5% during 1996; expected volatility of 67% in 1998, 59% in 1997, and 53% in 1996; and no expected dividend yield for the three years ended December 31, 1998. Because additional stock options are expected to be granted each year, the above pro forma disclosures are not representative of pro forma effects on reported financial results for future years.

If not utilized, the federal net operating loss carryforwards will begin to expire in 2010, and the state net operating loss carryforwards will begin to expire in 2003. The Company's federal and state research tax credit carryforwards for income tax purposes are approximately $10.7 million and $10.1 million, respectively. If not utilized, the federal tax credit carryforwards will begin to expire in 2010. Approximately $13 million of net operating loss carryforwards relate to acquired entities and expire beginning in 2010. Utilization of these net operating loss carryforwards may be limited by a cumulative stock ownership change of more than 50%, or by other limitations. Deferred tax assets of approximately $141 million as of December 31, 1998 pertain to certain net operating loss carryforwards and credit carryforwards resulting from the exercise of employee stock options. When recognized, the tax benefit of these loss and credit carryforwards are accounted for as a credit to additional paid-in capital rather than a reduction of the income tax provision. Deferred tax assets include approximately $1.6 million related to net operating loss carryforwards in various foreign jurisdictions. These carryforwards will expire if not utilized. NOTE 9 COMMITMENTS AND CONTINGENCIES OPERATING LEASES. During December 1998, the Company entered into a non-cancelable operating sublease agreement that will provide the Company with additional office space at its existing Santa Clara, California location. Additionally during 1998, the Company entered into various other non-cancelable operating lease agreements for its sales offices throughout the U.S. and its international subsidiaries. Future minimum lease payments under non-cancelable operating leases with initial terms of one year or more are $3.6 million in 1999, $3.3 million in 2000, $2.7 million in 2001, $2.6 million in 2002, $2.5 million in 2003, and $0.6 million thereafter.
