1. Nature of Business Carbonite, Inc. (the “Company”) was incorporated in the State of Delaware on February 10, 2005, and focuses on the development and marketing of personal computer backup service that enables users to backup, access, and restore data files online.

2. Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. In addition, through its wholly owned subsidiary Carbonite (China) Co., Ltd. (“Carbonite China”), the Company effectively controls a variable interest entity (“VIE”), Pan Sheng An Xin Internet Technology Co., Ltd., which is incorporated under the laws of the People’s Republic of China. The People’s Republic of China restricts foreign ownership of internet-related service companies. To comply with these foreign ownership restrictions, the Company operates its business in China through this VIE. The Company has entered into certain exclusive agreements with the VIE and its shareholders through Carbonite China, which provides the ability to direct the VIE’s most significant economic activities and to receive a majority of VIE’s economic benefits. Based on these contractual arrangements, the Company consolidates the VIE as required by Financial Accounting Standards Codification (“ASC”) 810-10, Consolidation, because the Company is the primary beneficiary of the VIE through Carbonite China. Despite the lack of majority ownership, there exists a parent-subsidiary relationship between the Company and the VIE through the aforementioned agreements, whereby the equity holders of the VIE effectively assigned all of their voting rights underlying their equity interest in the VIE to Carbonite China. In addition, the Company has the ability and intention to continue to exercise its rights to obtain substantially all of the profits and to absorb all of the expected losses of the VIE. All intercompany accounts and transactions between the Company, its subsidiaries, and the VIE have been eliminated in consolidation. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States. Use of Estimates in the Preparation of Financial Statements The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management’s estimates if past experience or other assumptions do not turn out to be substantially accurate, even if such assumptions are reasonable when made. Translation of Foreign Currencies The functional currency of the Company’s foreign subsidiary and VIE are their local currency. The financial statements of the Company’s foreign subsidiary and VIE in China are translated into U.S. dollars. The Company translates the assets and liabilities of at the exchange rates in effect at period-end. Revenues and expenses are translated using average exchange rates in effect during the year. Gains and losses from foreign currency translation are recorded to accumulated other comprehensive income (loss) included in stockholders’ deficit.   Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk primarily consist of cash and cash equivalents, short-term investments, and accounts receivable. The Company maintains its cash and cash equivalent and short-term investment balances with high-quality financial institutions and, consequently, the Company believes that such funds are subject to minimal credit risk. Cash equivalents and short-term investments consist of investment grade debt securities or money market funds investing in such securities. The Company sells its services primarily to consumer and small business customers. Payment for the majority of the Company’s sales occurs via credit card. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in the Company’s accounts receivable. For the periods presented, no customer represented 10% or more of accounts receivable or revenue. Revenue Recognition The Company derives revenue from online backup subscription services. These services are standalone independent service solutions, which are generally contracted for a one- to three-year term. Subscription arrangements include access to use the Company’s software via the internet. The Company recognizes revenue in accordance with ASC 605-10, Overall Revenue Recognition. Subscription revenue is recognized ratably on a daily basis upon activation over the subscription period, when persuasive evidence of an arrangement with a customer exists, the subscription period has been activated, the price is fixed or determinable, and collection is reasonably assured. Deferred revenues represent payments received from customers for subscription services prior to recognizing the revenue related to those payments. Cash Equivalents and Short-Term Investments The Company considers all highly liquid investments purchased with an original maturity of three months or less to be the equivalent of cash for the purpose of balance sheet and statement of cash flows presentation. Short-term investments in marketable securities are classified as available-for-sale and are recorded at fair value. Realized gains and losses are included in income. Unrealized gains and losses (excluding other-than-temporary impairments) are reported as a component of accumulated other comprehensive income (loss). The Company reviews its investments for other-than-temporary impairment whenever evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. There were no other-than-temporary impairments during the year ended December 31, 2011. Property and Equipment Property and equipment are stated at cost. Expenditures for repairs and maintenance are charged to expense as incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the consolidated statement of operations. Depreciation and amortization is provided using the straight-line method over the estimated useful lives of the assets, which are as follows:   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="49%"> </td> <td valign="bottom" width="4%"> </td> <td width="47%"> </td> </tr> <tr> <td valign="bottom" nowrap="nowrap"> Asset Classification </td> <td valign="bottom"> </td> <td valign="bottom"> Estimated Useful Life </td> </tr>   <tr> <td height="16"> </td> <td height="16" colspan="2"> </td> </tr> <tr> <td valign="top"> Computer equipment </td> <td valign="bottom"> </td> <td valign="bottom">2 – 4 years</td> </tr> <tr> <td valign="top"> Software </td> <td valign="bottom"> </td> <td valign="bottom">3 years</td> </tr> <tr> <td valign="top"> Furniture and fixtures </td> <td valign="bottom"> </td> <td valign="bottom">5 years</td> </tr> <tr> <td valign="top"> Leasehold improvements </td> <td valign="bottom"> </td> <td valign="bottom">Shorter of useful life or remaining life of lease</td> </tr>  </table>   Impairment of Long-Lived Assets The Company reviews property and equipment and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the recoverability of these assets is considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the assets exceeds its estimated fair value. The Company has not identified any impairment of its long-lived assets as of December 31, 2011, 2010 and 2009. Goodwill and Acquired Intangible Assets The Company records goodwill when consideration paid in a business acquisition exceeds the fair value of the net tangible assets and the identified intangible assets acquired. Goodwill is not amortized, but rather is tested for impairment annually or more frequently if facts and circumstances warrant a review. The Company performs its annual assessment for impairment of goodwill on November 30 and considers its business to be one reporting unit for the purpose of conducting this assessment. The assessment consists of estimating the fair value of the reporting unit (based on the Company’s market capitalization) and comparing this amount to the carrying value of the reporting unit (as reflected by the Company’s total stockholders’ equity). Based on the recent evaluation, the Company determined that its goodwill was not impaired. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. As the pattern of consumption of the economic benefits of the intangible assets cannot be reliably determined, the Company amortizes acquired intangible assets over their estimated useful lives on a straight-line basis. Software and Website Development Costs The Company follows the guidance of ASC 350-40, Internal Use Software and ASC 350-50, Website Development Costs, in accounting for its software and website development costs. The costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the application is substantially complete and ready for its intended use. Because the Company believes the majority of its development efforts are categorized in operation stage (post-implementation), no costs have been capitalized to date. These costs are included in the accompanying statements of operations as research and development expense. Advertising Expenses The Company expenses advertising costs as incurred. During the years ended December 31, 2011, 2010, and 2009, the Company incurred approximately $25.1 million, $23.6 million, and $10.8 million of advertising expense, respectively, which is included in sales and marketing expense in the accompanying statements of operations. Accounts Receivable Accounts receivable are recorded at the invoiced amount. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company specifically analyzes historical bad debts, the aging of the accounts receivable, creditworthiness, and current economic trends, to evaluate the allowance for doubtful accounts. Past due balances are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted, and the potential for recovery is considered remote.   Income Taxes The Company provides for income taxes under the liability method. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates in effect when the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance to reflect the uncertainty associated with their ultimate realization. The Company accounts for uncertain tax positions recognized in the consolidated financial statements by prescribing a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Comprehensive Income (Loss) All components of comprehensive income (loss) are required to be disclosed in the consolidated financial statements. Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from nonowner sources. Accumulated other comprehensive income consists of foreign currency translation adjustments and unrealized gains or losses on available-for-sale investments for all periods. Segment Information Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business in one operating segment. The Company does not disclose geographic information for revenue and long-lived assets as revenue and long-lived assets located outside the United States do not exceed 10% of total revenue and total assets. Accounting for Stock-Based Compensation Stock-based compensation is recognized as an expense in the financial statements based on the grant date fair value of the stock awards granted. For awards that vest based on service conditions, the Company uses the straight-line method to allocate compensation expense to reporting periods over the requisite service period. The grant date fair value of options granted is calculated using the Black-Scholes option-pricing model, which requires the use of subjective assumptions including volatility, expected term and the fair value of the underlying common stock, among others. Recently Issued and Adopted Accounting Standards In June 2011, the FASB issued new accounting guidance on the presentation of comprehensive income to provide companies with two options for presenting comprehensive income. Companies can present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders’ equity. This guidance was effective for the Company on January 1, 2012. As the new guidance relates only to how comprehensive income is disclosed and does not change the items that must be reported as comprehensive income, the Company does not believe that the adoption of this standard will have a material impact on its financial position or results of operations. In September 2011, the FASB issued ASU No. 2011-08, Testing Goodwill for Impairment (the revised standard). The revised standard is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a “qualitative” assessment to determine whether further impairment testing is necessary. The revised standard was effective for the Company on January 1, 2012. The Company does not believe that the adoption of this amendment will have a material impact on the Company’s financial position or results of operations.

3. Net Loss per Share The Company calculates basic and diluted net loss per share of common stock by dividing the net loss adjusted for the dividend on the redeemable convertible preferred stock by the weighted average number of shares of common stock outstanding during the period. The Company has excluded (a) all unvested restricted shares of common stock that are subject to repurchase and (b) the Company’s other potentially dilutive shares, which include redeemable and convertible preferred stock, a warrant for redeemable convertible preferred stock, and outstanding options to purchase common stock, from the weighted average number of shares of common stock outstanding as their inclusion in the computation for all periods would be anti-dilutive due to net losses. The Company’s redeemable and convertible preferred stock are participating securities as defined by ASC 260-10, Earnings Per Share, but are excluded from the earnings per share calculation as they do not have an obligation to share in the Company’s net losses. The Company’s net loss per share is calculated as follows (in thousands, except per share data):   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse;

The Company applies the guidance in ASC 820, Fair Value Measurements and Disclosures, (“ASC 820”), which provides that fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets and liabilities or market corroborated inputs. Level 3: Unobservable inputs are used when little or no market data is available, which requires the Company to develop its own assumptions about how market participants would value the assets or liabilities. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible in its assessment of fair value. The Company’s assets and liabilities that are measured at fair value on a recurring basis, by level, within the fair value hierarchy are summarized as follows (in thousands):   <table cellspacing="0"

5. Acquisition, Goodwill, and Acquired Intangible Assets In June 2011, the Company acquired substantially all of the assets of Phanfare, Inc., for $1.9 million, net of cash acquired, and the assumption of certain liabilities. Phanfare’s service enables users to create, maintain, and share online photo and video albums. The Company maintains the former service, employees, and office location of Phanfare. The results of operations for the acquisition have been included in the Company’s operations since the date of acquisition and were not material for the periods presented.   The acquisition of Phanfare has been accounted for as a purchase of a business and, accordingly, the total purchase price has been allocated to the tangible and identifiable intangible assets acquired and the net liabilities assumed based on their respective fair values on the acquisition date.

8. Redeemable and Convertible Preferred Stock and Stockholders’ Equity (Deficit) Initial Public Offering In August 2011, the Company closed its initial public offering (“IPO”) of 7,187,500 shares of common stock at a price of $10.00 per share, including 937,500 shares of common stock pursuant to exercise of the underwriters’ option to purchase additional shares. Of the total shares of common stock sold in the IPO, 6,303,973 shares were sold by the Company and 883,527 were sold by selling stockholders. The Company received aggregate proceeds of $58.6 million, net of underwriters’ discounts and commissions, but before deducting offering expenses of approximately $3.0 million. Upon the closing of the IPO, the Company’s outstanding shares of redeemable and convertible preferred stock (“Preferred Stock”) converted into 13,483,473 shares of common stock and all outstanding warrants to purchase Preferred Stock converted into warrants to purchase 11,316 shares of common stock. Also simultaneously with the closing of the IPO, the Company’s charter was amended and restated to authorize 45,000,000 shares of common stock, par value $0.01 per share, and 6,000,000 shares of preferred stock, par value $0.01 per share, all of which preferred stock is undesignated. Stock Split In December 2009, the Board of Directors and shareholders approved a 3 for 1 stock split of the Company’s common stock. As a result of this action, every share of common stock (including all authorized, issued and outstanding shares of common stock and all outstanding warrants and options to purchase shares of common stock) was split into three shares of common stock bearing the same par value. All of the Company’s authorized, issued, and outstanding shares of common stock (including all outstanding warrants and options to purchase shares of common stock) since inception, have been restated in these financial statements to reflect the effect of the common stock split. Redeemable and Convertible Preferred Stock Prior to the Company’s IPO, at which time all shares of Preferred Stock were converted into shares of common stock, the Company’s Preferred Stock consisted of the following (in thousands, except share and per share amounts):   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="88%"> </td> <td valign="bottom" width="7%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">December 31, 2010</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Redeemable convertible preferred stock: </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> </tr> <tr> <td valign="top"> Series A-2, $0.01 par value; 506,646 shares authorized, 502,874 shares issued and outstanding, at redemption value (liquidation value of approximately $4.4 million) </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">4,404</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Convertible preferred stock: </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> </tr> <tr> <td valign="top"> Series A, $0.01 par value; 421,210 shares authorized, issued, and outstanding (liquidation value of approximately $2.4 million) </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,793</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Series A-1, $0.01 par value; 194,319 shares authorized, issued, and outstanding (liquidation value of approximately $1.1 million) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">815</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> Series B, $0.01 par value; 1,259,319 shares authorized, issued, and outstanding (liquidation value of approximately $18.6 million) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">15,200</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Series B-2, $0.01 par value; 395,100 shares authorized and 368,400 shares issued and outstanding (liquidation value of approximately $6.4 million) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">5,401</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> Series C, $0.01 par value; 1,206,802 shares authorized and 1,162,579 shares issued and outstanding (liquidation value of approximately $24.2 million) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">21,194</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Series D, $0.01 par value; 585,790 shares authorized and 563,822 and 585,790 shares issued and outstanding (liquidation value of approximately $21.2 million) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">19,923</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr> <td valign="top"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">64,326</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table>   Prior to the Company’s IPO and the related conversion of all shares of Preferred Stock into shares of common stock, the rights, privileges, and preferences of the Preferred Stock were as follows: Dividends The holders of Preferred Stock were entitled to receive, out of funds lawfully available, dividends, when, as and if they were declared by the Board, at an annual rate per share, without compounding, equal to 6% of the original purchase price. Dividends accrued, whether or not declared, and were cumulative and payable upon the occurrence of a liquidation event for all Preferred Stock, as well as upon redemption for Series A-2. Therefore, dividends were accreted on the Series A-2 such that it was presented at redemption value. No dividends were declared through the date on which the Preferred Stock was converted into common stock. Redemption Holders of Series A-2 could have elected to have their shares redeemed at any time after December 31, 2012, upon written request to the Company. The redemption amount would have been the original issue price, plus any accrued but unpaid dividends. Dividends were accreted on Series A-2 such that it was presented at redemption value. Upon conversion of the Series A-2 to common stock, all accrued dividends were reversed through accumulated deficit. Additional Rights, Preferences, and Privileges In addition to those rights described above and the registration rights described below, the holders of the Company’s Preferred Stock had certain voting rights, liquidation preferences, and conversion privileges. All rights, preferences and privileges associated with the Preferred Stock, other than the registration rights described below, were terminated at the time of the Company’s IPO in conjunction with the conversion of all outstanding shares of Preferred Stock into shares of common stock. Registration Rights Pursuant to an investors’ rights agreement, the holders of the Company’s common stock that resulted from the conversion of the Preferred Stock have certain registration rights. The holders have the right to demand that the Company register such shares of common stock pursuant to the Securities Act of 1933, as amended. Subject to certain limitations, the Company shall bear the fees, costs and expenses of such registration, other than underwriting discounts and commissions. The Company is not required to settle such registration rights by delivery of registered shares or by a net cash settlement. Warrants In October 2006, in connection with a commercial line of credit, the Company issued a warrant to purchase shares of Series A-2, which, at the time of the Company’s IPO, was converted into a warrant to purchase 11,316 shares of common stock at a price of $2.32 per share (the “Warrant”). The Warrant is exercisable at any time through expiration in October 2013. The Company valued the Warrant at the date of grant at $18 thousand, and recorded the fair value of the Warrant as a charge to interest expense. The Company remeasured the fair value of the Warrant each reporting period in accordance with the provisions of ASC 480, Distinguishing Liabilities from Equity, resulting in a fair value of $82 thousand as of December 31, 2010, which was recorded in other long-term liabilities. At the time of conversion of the Warrant in connection with the Company’s IPO, the fair value of the Warrant was $74 thousand, which was reclassified as a component of additional paid-in capital. No portion of the Warrant has been exercised as of December 31, 2011.

9. Stock-based Awards The Company’s 2005 Stock Incentive Plan (the “2005 Plan”) provided for granting of incentive stock options, non-qualified options, restricted stock, or other awards to the Company’s employees, officers, directors, and outside consultants up to an aggregate of 3,601,551 shares of the Company’s common stock. In conjunction with the effectiveness of the 2011 Equity Award Plan (the “2011 Plan”), the Board of Directors voted that no further stock options or other equity-based awards would be granted under the 2005 Plan. In 2011, the Company’s Board of Directors and stockholders adopted the 2011 Plan, which became effective concurrently with the consummation of the Company’s IPO on August 11, 2011. The 2011 Plan provides for the issuance of stock options, restricted stock, and other stock-based awards to the employees, officers, directors, and consultants of the Company or its subsidiaries. In connection with the approval of the plan, the Company reserved 1,662,000 shares of common stock for issuance under the 2011 Plan. On January 1 st of each year, beginning on January 1, 2012, the number of shares reserved under the 2011 Plan will increase by the lesser of 1,500,000 shares, 4.0% of the outstanding shares of common stock and common stock equivalents, or another amount determined by the Company’s Board of Directors. As of December 31, 2011, 794,800 shares of common stock were available for future grant under the 2011 Plan.

Certain option awards provide for accelerated vesting if there is a change of control, as defined in the 2005 Plan or 2011 Plan, as applicable. The Company has generally granted stock options at exercise prices not less than the fair market value of its common stock on the date of grant. The Company records compensation expense related to stock options based on the estimated fair value of the stock option on the date of grant amortized over the service periods for the individual awards, which generally equals the vesting periods. The Company uses the straight-line amortization method for recognizing stock-based compensation expenses. Determining the appropriate fair value model and calculating the fair value of stock-based payment awards require the use of highly subjective estimates and assumptions, including the estimated fair value of the Company’s common stock. Following its IPO, the Company used the quoted market price of its common stock to establish fair value of the common stock underlying stock options. Prior to the IPO, because there was no public market for the Company’s common stock, the Company’s Board of Directors determined the fair value of the Company’s common stock with input from management, based on the report of an unrelated third-party valuation specialist.   The Company estimates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model, which further requires the use of highly subjective estimates and assumptions, including expected stock price volatility, expected term of an award, risk-free interest rate, and expected dividend yield. The assumptions used to estimate the fair value of the stock options using the Black-Scholes option-pricing model were as follows for the years ended December 31, 2011, 2010, and 2009:   <table cellspacing="0" cellpadding="0" width="100%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="56%"> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> <td valign="bottom" width="1%"> </td> <td> </td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="5" align="center" style="border-bottom:1px solid #000000">Years Ended December 31,</td> </tr> <tr> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="center" style="border-bottom:1px solid #000000">2011</td> <td valign="bottom"> </td> <td valign="bottom" align="center" style="border-bottom:1px solid #000000">2010</td> <td valign="bottom"> </td> <td valign="bottom" align="center" style="border-bottom:1px solid #000000">2009</td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Weighted-average fair value of common stock </td> <td valign="bottom"> </td> <td valign="bottom" align="center">$12.20</td> <td valign="bottom"> </td> <td valign="bottom" align="center">$7.32</td> <td valign="bottom"> </td> <td valign="bottom" align="center">$2.08</td> </tr> <tr> <td valign="top"> Risk-free interest rate </td> <td valign="bottom"> </td> <td valign="bottom" align="center">2.12% to 2.4%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">1.45% to 3.04%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">2.09% to 3.04%</td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Expected dividend yield </td> <td valign="bottom"> </td> <td valign="bottom" align="center">—%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">—%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">—%</td> </tr> <tr> <td valign="top"> Expected volatility </td> <td valign="bottom"> </td> <td valign="bottom" align="center">53% to 62%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">61% to 64%</td> <td valign="bottom"> </td> <td valign="bottom" align="center">70% to 74%</td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Expected term (in years) </td> <td valign="bottom"> </td> <td valign="bottom" align="center">5.8 to 6.1</td> <td valign="bottom"> </td> <td valign="bottom" align="center">6.1</td> <td valign="bottom"> </td> <td valign="bottom" align="center">5 to 6.1</td> </tr>  </table> Risk-Free Interest Rate The Company bases the risk-free interest rate that it uses in the option valuation model on U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. Expected Dividend Yield The Company has not paid, and does not anticipate paying, cash dividends on shares of common stock; therefore, the expected dividend yield is assumed to be zero in the option valuation model. Expected Volatility Until the Company’s IPO, as there had been no public market for the Company’s common stock, the Company determined the volatility for options granted based on an analysis of reported data for a peer group of companies that issued options with substantially similar terms. Beginning at the time of the Company’s IPO, the expected volatility of options granted has been determined using a combination of the historical volatility measures of this peer group of companies for a period equal to the expected term of the option. Expected Term The Company has limited historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior for its stock option grants. As a result, for stock option grants made during the years ended December 31, 2011, 2010, and 2009 the expected term was estimated using the “simplified method.” The simplified method is based on the average of the vesting tranches and the contractual life of each grant. Forfeitures The Company is required to estimate forfeitures at the time of grant, and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures, and records stock-based compensation expense only for those awards that are expected to vest.   The following table

weighted-average grant date fair value of options granted to employees during the years ended December 31, 2011, 2010, and 2009 was $6.47, $4.68, and $2.08 per share, respectively. The total intrinsic value of options exercised during the years ended December 31, 2011, 2010, and 2009 was approximately $8.0 million, $1.2 million, and $0.1 million, respectively. At December 31, 2011 and 2010, there were approximately $9.4 million and $2.9 million of unrecognized stock-based compensation cost, net of estimated forfeitures, respectively, related to unvested stock options which is expected to be recognized over a weighted-average period of 2.96 and 3.48 years, respectively. The total unrecognized stock-based compensation cost will be adjusted for future changes in estimated forfeitures. Incentive Unit Agreements In 2011, the Company’s Board of Directors adopted the Incentive Unit Plan, which provides up to an aggregate of 60,000 incentive units (“Units”) to certain employees of its subsidiary in China to afford these employees the benefit of any appreciation in the value of the Company. The Units have a five year term and vest upon a performance condition, which has been satisfied, and a service period of up to four years. Upon vesting, the recipients of Units are entitled to a cash bonus based on the difference between the fair value of the Company’s stock and the base value set forth in their respective Incentive Units Agreements. As of December 31, 2011, 39,250 Units are outstanding with a weighted average base value of $8.58. These outstanding Units are being accounted for as liability awards and the liability for such awards was $0.1 million at December 31, 2011. In January 2012, the Board of Directors determined to cease to issue any further grants pursuant to the Incentive Unit Plan. Restricted Stock In 2009, the Company sold an aggregate of 72,000 shares of common stock at the fair value of $1.31 per share to non-employee members of the Board of Directors under restricted stock agreements in accordance with the terms of the Company’s 2005 Plan. During 2009, due to the departure of one board member, 18,000 of these shares were forfeited. The restricted stock vests ratably over three years from the grant date. In the event that a member of the Board of Directors ceases to serve on the Company’s Board of Directors for any reason, with or without cause, the Company has the right to repurchase some or all of the unvested shares at the fair values on the dates of issuance. The fair value of the restricted shares is based on the fair value of the Company’s common stock on the date of grant. Stock-based compensation expense related to restricted shares is recognized on a straight-line basis over the requisite service period. There are no performance-based measures.

The Company did not provide for income taxes in the years ended December 31, 2010 and 2009 due to net losses. As of December 31, 2011, the Company had U.S. federal, state, and foreign net operating loss carryforwards of $89.0 million, $83.9 million and $1.0 million, respectively. Included in the federal net operating loss carryforward is $1.6 million that relates to excess tax deductions from share-based payments, the tax benefit of which will be recorded as an increase in additional paid-in capital when the deductions reduce current taxes payable. As of December 31, 2010, the Company had federal and state net operating loss carryforwards of approximately $72.6 million and $72.4 million, respectively. The federal net operating loss carryforwards will expire at various dates beginning in the year 2026 through 2032. State net operating loss carryforwards will expire at various dates beginning in 2012 through 2017. At December 31, 2011 and 2010, the Company had approximately $2.4 million and $1.4 million, respectively, of federal and state research and development tax credit carryforwards available to reduce future income taxes payable, which will expire at various dates beginning in the year 2023 through 2032. Management of the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets. As required by the provisions of ASC 740, management has determined that it is more-likely-than-not that the Company will not utilize the benefits of federal and state deferred tax assets for financial reporting purposes. Accordingly, the deferred tax assets have been fully reserved at December 31, 2011 and 2010. The valuation allowance increased approximately $8.9 million and $10.1 million during the years ended December 31, 2011 and 2010, respectively, due primarily to the increase in the net operating loss carryforwards and research and development tax credits. Future changes in Company ownership may limit the amount of net operating loss carryforwards and research and development credit carryforwards that can be utilized annually to offset future taxable income and taxes, respectively. In general, an ownership change, as defined by Section 382 of the Internal Revenue Code of 1986, as amended, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. The Company performed an analysis of its changes in ownership through December 31, 2011 and has adjusted its net operating loss carryforwards and research and development credit carryforwards to reflect the current usage limitations. The Company’s reserves related to taxes and its accounting for uncertain tax positions are based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more-likely-than-not to be realized following resolution of any potential contingencies present related to the tax benefit. As of December 31, 2011 and 2010, the Company had no unrecognized tax benefits. The Company will recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2011, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s consolidated statements of operations. The statute of limitations for assessment by the Internal Revenue Service (“IRS”) and state tax authorities is open for tax years ending December 31, 2008, 2009, 2010, and 2011, although carryforward attributes that were generated prior to tax year 2008 may still be adjusted upon examination by the IRS or state tax authorities if they either have been or will be used in a future period. There are currently no federal or state audits in progress.

11. Commitments and Contingencies Operating Leases The Company leases various facilities under leases that expire at varying dates through 2016. Certain of these leases contain renewal options, and require the Company to pay operating costs, including property taxes, insurance, and maintenance. The Company has lease agreements to rent office space in Boston, Massachusetts (corporate headquarters) Lewiston, Maine, Princeton, New Jersey, and Beijing, China, expiring in 2016 or earlier. The Company has lease agreements to rent data center space in Boston, Massachusetts, Wakefield, Massachusetts and Phoenix, Arizona, expiring in 2016 or earlier. The terms of the several of these leases include escalating rent and free rent periods. Accordingly, the Company recorded a deferred rent liability related to the free rent and escalating rent payments and rent is being recognized on a straight-line basis over the terms of the leases. At December 31, 2011 and 2010, $0.4 million and $0.2 million, respectively, are included in accrued expenses and other long-term liabilities related to the deferred rent. The Company also maintains a hosting service agreement with a third-party data center vendor that is subject to annual renewal and a 120 day cancellation right. Future non-cancellable minimum lease payments under all operating leases as of December 31, 2011, are as follows (in thousands):   <table cellspacing="0" cellpadding="0" width="84%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="69%"> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> <td valign="bottom" width="5%"> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td valign="bottom" nowrap="nowrap"> Years Ended December 31, </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Office Leases</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Data Center Leases</td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" colspan="2" align="center" style="border-bottom:1px solid #000000">Total</td> <td valign="bottom"> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> 2012 </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,234</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">1,932</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">3,166</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> 2013 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,531</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,802</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">3,333</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> 2014 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,279</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,340</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">2,619</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> 2015 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,368</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,221</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">2,589</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> 2016 </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,408</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">63</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">1,471</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr> <td valign="top"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">6,820</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">6,358</td> <td nowrap="nowrap" valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">13,178</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table>   Other Non-cancellable Commitments As of December 31, 2011, the Company had non-cancelable commitments of $5.1 million payable in 2012, and $0.7 million payable in 2013, and $0.3 million payable in 2014, primarily consisting of marketing and technology services contracts. Litigation In August 2010, Oasis Research, LLC (“Oasis Research”) filed a lawsuit against the Company and many other companies in the U.S. District Court for the Eastern District of Texas, alleging, with respect to the Company, that the Company’s online backup storage services infringe four patents held by Oasis Research. Oasis Research seeks an award for damages in an unspecified amount. The Company expects that a trial date will be set for late 2012 or early 2013. Neither the ultimate outcome of this litigation nor an estimate of a probable loss or any reasonably possible losses can be assessed at this time. The Company intends to defend itself vigorously. In the ordinary course of business the Company is involved in litigation incidental to its business; however, the Company’s management is not aware of any pending legal proceeding or other loss contingency, whether asserted or unasserted, affecting the Company for which it might become liable or the outcome of which management expects to have a material impact on the Company.

12. Retirement Plan The Company has a 401(k) defined contribution savings plan for its employees who meet certain employment status and age requirements. The plan allows participants to defer a portion of their annual compensation on a pre-tax basis. The Company did not contribute to this plan for the years ended December 31, 2011, 2010, and 2009. Effective January 1, 2012, the Company has elected to make a matching contribution of up to 4% of each employee’s wages.

13. Related Party Transactions One investor in certain of the Company’s perferred stock financings is also the Company’s Assistant Secretary and primary outside legal counsel. Legal fees paid to this firm totaled $4.2 million, $1.1 million and $0.5 million for the years ended December 31, 2011, 2010, and 2009, respectively. At December 31, 2011 and 2010, the Company had outstanding payables and accruals to the legal firm of $0.4 million and $0.5 million, respectively. In December 2011, in connection with an employee/affiliate exercise of stock options, the Company remitted $0.1 million on such employee/affiliate’s behalf for payroll taxes. The Company was reimbursed in full in January 2012.

14. Revolving Credit Facility The Company maintains a revolving line of credit with a bank pursuant to which the Company may borrow up to $15 million through August 31, 2012. Advances under the line of credit bear interest on the outstanding daily balance, at an annual rate equal to the lender’s prime reference rate plus 1%. The Company has pledged its accounts receivable, equipment, and shares of its subsidiaries to the lender to secure its obligations under the credit facility, and has also agreed not to grant a security interest in or pledge its intellectual property to any third party.
