                                DOUBLECLICK INC.

                        1999 Employee Stock Purchase Plan

                          Notes to Financial Statements


1.   Description of the plan

     The following description of the DoubleClick Inc. 1999 Employee Stock
     Purchase Plan (the "Plan")provides only general information. Participants
     should refer to the Plan document for a more complete statement of the
     Plan's provisions.

     General

     The Plan is intended to promote the interests of DoubleClick Inc. (the
     "Company") by providing eligible employees with the opportunity to acquire
     a proprietary interest in the Company through participation in a payroll
     deduction based employee stock purchase plan designed to qualify under
     Section 423 of the Internal Revenue Code. Under the Plan, shares of the
     Company's common stock will be offered through a series of successive
     Offering Periods, each of which cannot exceed 24 months in length. Each
     Offering Period is comprised of a series of one or more consecutive
     Purchase Periods in which participants' payroll deductions are accumulated.

     On the last business day of each Purchase Period (the "Purchase Date"),
     these accumulated deductions are used to purchase shares of the Company's
     common stock at a per share price equal to 85% of the lesser of (1) the
     closing price of a share of the Company's common stock on the participant's
     entry date into the Offering Period and (2) the closing price of a share of
     the Company's common stock on the last business day of the Purchase Period.
     Should the per share closing price of the Company's common stock on any
     Purchase Date within an Offering Period be less than the per share closing
     price of a share of the Company's common stock on the start date of that
     Offering Period, then that Offering Period automatically terminates and a
     new Offering Period begins on the next business day following the Purchase
     Date.

     For period from April 3, 2000 (inception) to March 31, 2001, the Plan had
     two consecutive Offering Periods that extended from April 3, 2000 to
     September 30, 2000 and October 1, 2000 to March 31, 2001, respectively.

     The Plan, which was approved by the Company's Board of Directors on
     November 30, 1999, became effective on April 3, 2000 and was initially
     authorized to issue up to 1,000,000 previously un-issued or treasury shares
     of stock to participants. The number of shares of common stock available
     for issuance under the Plan automatically increases on the first trading
     day of January each calendar year by an amount equal to the lesser of 1% of
     the total number of shares of common stock outstanding on the last trading
     day in December of the immediately preceding calendar year or 900,000
     shares At March 31, 2001, Plan participants had purchased 239,986 whole
     shares of stock since the Plan's inception, leaving 1,660,014 whole shares
     of stock available for future purchases by Plan participants.

     The Plan is neither qualified under Section 401 (a) of the Internal Revenue
     Code of 1986, as amended, nor subject to any of the provisions of the
     Employee Retirement Income Security Act of 1974 ("ERISA").

     Eligibility

     All full-time or part-time employees of the Company and its eligible
     subsidiaries, who customarily work at least 20 hours per week and five
     months a year are eligible to participate in the Plan. Eligible employees
     may only enroll in the Plan prior to the beginning of an Offering or
     Purchase Period.

                    Notes to Financial Statements - continued


     Stock purchases

     On the last business day of each Purchase Period, the amount of each
     participant's accumulated payroll deductions is applied towards the
     purchase of the maximum number of whole shares of Company common stock
     possible, determined by dividing the participant's total contribution by
     the per-share purchase price in effect for the Purchase Period. The maximum
     number of shares of common stock purchasable per participant in any one
     Purchase Period cannot exceed 500 shares, and the aggregate number of
     shares of common stock purchasable by all participants in any one Purchase
     Period cannot exceed 250,000 shares. Purchased shares of common stock are
     then issued by the Company and transferred to a brokerage account outside
     of the Plan in the name of the participant.

     Participant contributions

     Participants may elect to have 1% to 10% of their "Cash Compensation" (as
     defined in the Plan) deducted on an after-tax basis for the purchase of
     shares of the Company's common stock subject to a limit of $25,000 worth of
     stock for each year in which the Offering Period is outstanding, based on
     the closing price of the Company's common stock on the participant's entry
     date into the Offering Period. Increases in participants' deduction
     percentages take effect on the commencement of a new Purchase Period.
     Participants may reduce their deduction percentage a maximum of one time
     per Purchase Period with immediate effect. No interest is paid or accrued
     on participants' accumulated payroll deductions. Once made, the Company may
     use the payroll deductions for any corporate purpose. The Company has no
     obligation to segregate employees' payroll deductions from any other funds
     of the Company or to hold funds representing the same pending the
     application of such amount to the purchase of shares at the end of each
     Payment Period in accordance with the Plan.

     Any accumulated contribution amount that is insufficient to purchase a
     whole share of common stock at the end of a Purchase Period is carried
     forward and applied to the purchase of whole shares of stock in future
     Purchase Periods or refunded to the participant upon withdrawal from the
     Plan. Such amounts are recorded as the liability "Residual participant
     contributions" at March 31, 2001.

     Employer contributions

     The 15% discount from market value granted to Plan participants on the
     purchase of whole shares of common stock at the end of each Purchase Period
     represents the Company's non-cash contribution to the Plan. This non-cash
     contribution amounted to $672,558 for the year ended March 31, 2001.

     Participant withdrawals

     Plan participants may withdraw from the Plan at any time prior to the next
     scheduled Purchase Date by properly notifying the Company. A participant's
     accumulated payroll deductions prior to withdrawal will, at the election of
     the participant, be immediately refunded or held for the purchase of whole
     shares of common stock on the next Purchase Date.

     Participants who cease to be Eligible Employees for any reason during a
     Purchase Period will have their accumulated payroll deductions refunded
     immediately.

                    Notes to Financial Statements - continued


     Plan termination

     Although it has not expressed any intent to do so, the Company has the
     right to terminate the Plan at any time. The Plan will also terminate at
     the earlier of the last business day in January 2010 or the date when all
     of the shares of common stock reserved for the purposes of the Plan have
     been purchased. Upon termination of the Plan, all payroll deductions not
     used to purchase shares of common stock will be refunded to Plan
     participants.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of accounting

     The accompanying financial statements have been prepared using the accrual
     basis of accounting.

     Administrative expenses

     The Company bears all costs in connection with the Plan, including
     administrative fees and all fees associated with the issuance of common
     stock. Administrative expenses related to the Plan amounted to
     approximately $8,000 for the year ended March 31, 2001.

     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 and
     disclosure of contingent assets and liabilities as of the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

3.   INCOME TAXES

     The Plan meets the requirements of an "employee stock purchase plan" as
     defined by Section 423 of the Internal Revenue Code. As such, the Plan is
     not obligated to file income tax returns or pay income taxes. Under Section
     423, a participating employee will generally recognize no income, and the
     Company will be entitled to no corresponding deduction, for federal income
     tax purposes when an employee enrolls in the Plan or when a participant
     purchases whole shares of common stock under the Plan.

4.   CHANGE IN PLAN YEAR

     Following the approval of the Board of Directors on February 27, 2001, the
     Plan adopted a fiscal year ending on January 31, effective for the 2002
     fiscal year. To account for this change, the first Purchase Period for the
     2002 fiscal year will be shortened by two months and will extend from April
     1 to July 31, 2001. As a result, the entire 2002 fiscal year will be 10
     months in length.
