Pete Krainik
DoubleClick Inc.
111 Eighth Avenue
New York, NY 10011

Dear Pete:

          This letter agreement will confirm our understandings and obligations in connection with your separation from DoubleClick Inc. As used in this letter agreement, “DoubleClick” is defined to include, as appropriate, DoubleClick Inc., any directly or indirectly held subsidiary, any affiliated entity, and any successor to any of the foregoing.

          Resignation. You hereby resign, effective January 1, 2005, from your position as DoubleClick’s Chief Marketing Officer and from any other currently held positions with DoubleClick. This letter agreement confirms that, as of January 1, 2005, you are no longer an “executive officer” of DoubleClick (as that term is defined in Rule 3b-7 under the Securities Exchange Act of 1934) and that you no longer perform a “policy-making function” (as that term is used in Rule 16a-1 under the Securities Exchange Act of 1934). From today through and including the earlier of July 1, 2005, or the date upon which you begin new full-time employment, which date will be the effective date of your termination (the “Termination Date”), you will continue to be employed by DoubleClick. During the period from today through and including January 1, 2005, you will assist in those special projects as may be designated by DoubleClick’s Chief Executive Officer or President and reasonably acceptable to you. DoubleClick acknowledges that you will be able to serve in your new capacity without being present in DoubleClick’s offices on a daily basis. During the period from January 2, 2005 through the Termination Date, you will be on a leave of absence with pay (the “Leave Period”). During the Leave Period, you will perform no work for DoubleClick, will have no DoubleClick authority, and agree not to bind or attempt to bind DoubleClick as its agent in any way.

          Separation Pay. In consideration for your agreeing to the terms of this agreement, you (or, in the event of your death, your estate) will receive: (a) your regular salary at your current base rate of pay for the period from today through and including the Termination Date payable in the ordinary course of business, provided that in the event that the Termination Date occurs prior to July 1, 2005, the then

remaining unpaid balance shall be paid to you in a lump sum within thirty (30) days of the Termination Date rather than through salary continuation; and (b) a lump-sum payment of $93,600 in payment of your 2004 bonus, payable upon the earlier of (i) thirty (30) days after the Termination Date or (ii) at the same time such bonus payments are paid to employees in the ordinary course of business ((a) and (b) together the “Separation Pay”). All payments will be less customary deductions and withholdings.

          You agree to notify me in writing upon your acceptance of full-time employment with any other employer.

          Stock Sales. You acknowledge that you are familiar with the trading and reporting requirements applicable to a former Section 16 reporting officer, and that it is your responsibility to ensure that all applicable filings are made as required under the federal securities laws. DoubleClick will assist you with those filings through the Termination Date provided that you notify our Legal Department not later than the day of the trade. Until February 15, 2005, you agree to continue to abide by DoubleClick’s insider trading policies, including all applicable blackout periods, for which purposes you shall remain a “Listed Employee.”

          Stock Options. This agreement confirms that all stock options granted to you by DoubleClick prior to the date of this letter will continue to vest according to their respective terms through and including January 1, 2005.

          Release of Claims. You, on your own behalf and on behalf of any spouse, heirs, legal representatives, successors-in-interest, and assigns, waive, release, and discharge DoubleClick Inc., its present and former subsidiaries, divisions, departments, affiliated entities, predecessors, partners, joint venturers, directors, officers, shareholders, agents, employees, successors, and assigns from any and all claims, rights, demands, debts, obligations, damages or accountings of whatever nature which you may have, may have had, or, in the future, may believe you had, against DoubleClick occurring prior to the date of your signing this agreement, whether known or unknown, asserted or unasserted, including but not limited to: (a) all claims and liability for any acts that violated or may have violated your rights under any contract, tort, or other common law, any federal, state, or local fair employment practices or civil rights law or regulation, any employee relations statute, executive order, law, regulation, or ordinance, any workers compensation law, or any other duty or obligation of any kind, including but not limited to rights created by 42 U.S.C. § 1981, Title VII of the Civil Rights Act of 1964 (“Title VII”), the Age Discrimination in Employment Act (“ADEA”), the Americans with Disabilities Act (“ADA”), the Family and Medical Leave Act (“FMLA”), the Sarbanes-Oxley Act of 2002, 18 U.S.C. § 1514A, and all other federal, state, and local laws prohibiting employment discrimination of whatever kind or nature; (b) all liability for any claims whatsoever which were or may have been alleged against or imputed to DoubleClick by you or anyone acting on your behalf; (c) all rights to or claims for wages, commissions, monetary or equitable relief, or

compensatory, punitive, or liquidated damages, or reemployment or reinstatement in any position; and (d) all rights to or claims for attorneys’ fees, costs, or disbursements.

          On or promptly following the Termination Date, you hereby agree to execute a separate release in the form attached hereto as Exhibit A. You acknowledge and agree that DoubleClick’s obligation to pay any Separation Pay to you hereunder (other than salary continuation) is expressly contingent upon your execution of the release attached as Exhibit A.

          Confidentiality. You shall keep the terms and conditions of this agreement strictly confidential other than as required by law.

By signing below, you agree that you will return to DoubleClick, on or before January 1, 2005, any documents (including electronic documents, disks, and files) that you received and/or created as part of your employment with DoubleClick and that remain in your possession, custody, or control, and you further agree that you will not, to the best of your knowledge and belief, have retained (yourself or through an agent) any copies thereof. You further agree that you will, on or before January 1, 2005, return all tangible company property that remains in your possession, custody, or control, including but not limited to company-sponsored credit cards and/or calling cards, cellular telephones, computer equipment, keys, badges, and any other company property; notwithstanding the forgoing, however, you may retain your Company laptop until February 1, 2005 at which time it must be returned to the Company.

You hereby acknowledge that the scope of this non-competition obligation is fair and reasonable, and is given in consideration of the other benefits set forth in this agreement.

          Non-Disparagement. DoubleClick agrees not to disparage your professional or personal reputation.

However, DoubleClick will not (except to the extent otherwise currently provided in DoubleClick’s certificate of incorporation or bylaws) be obligated to indemnify or defend you in any instance in which DoubleClick, in its

reasonable discretion exercised in good faith, believes that you have been involved in an act of fraud, gross negligence, or willful misconduct.

          Benefits. You are entitled to the following benefits: You will receive any accrued but unused Paid Time Off days through January 1, 2005.

Your entitlement to stock option vesting and change of control benefits under DoubleClick’s Stock Option Plan shall cease completely as of that date.

          Your benefits and coverage under the medical insurance arrangements to which you are subject as of the date of this agreement will continue, under the current terms and conditions, through the last day of the month in which the Termination Date falls, on which date such benefits and coverage will cease and you will be eligible to continue such benefits and coverage at your expense pursuant to the federal law known as COBRA. You will be receiving more detailed information concerning your option to continue your health coverage under separate cover. Other than the foregoing benefits and the Separation Pay set forth above, you will not be entitled to any form of payment or benefit.

          The Company agrees to not contest your application for unemployment insurance benefits.

          Entire Agreement/Choice of Law/Severability. This agreement contains the entire agreement between the parties and shall be governed by the laws of the State of New York without giving effect to its principles of conflicts of law. You hereby agree that you are subject to the jurisdiction of the courts of the State of New York. This agreement may not be changed orally, but only by an agreement in writing signed by the party against whom enforcement of any waiver, change, modification or discharge is sought.

          Should any provision of this agreement be declared or be determined by any court of competent jurisdiction to be illegal or invalid, the validity of the remaining parts, terms, or provisions shall not be affected thereby and said illegal or invalid part, term, or provision shall be deemed not to be part of this agreement.

          Remedy for Breach of Promises. If you commence, continue, join in, or in any other manner attempt to assert any claim released in this agreement, or otherwise breach any promises made in this agreement, DoubleClick shall have a right to the return of all amounts and benefits paid hereunder, and to cease furnishing to you

any further salary, vesting of stock options, and medical insurance coverage described in this agreement. DoubleClick’s rights under this paragraph are without prejudice to its other rights, including the continued effect of your release and waiver of any and all claims against DoubleClick and the right of DoubleClick to seek preliminary and permanent injunctive relief in court to preclude any irreparable harm arising out of a violation or threatened violation of this Agreement, and to seek an award of compensatory and/or exemplary damages arising from any breaches of this agreement.

          Acknowledgment. You acknowledge by signing this agreement that you have read it in its entirety, understand all of its terms and conditions, and knowingly and voluntarily assent to those terms and conditions. Any alterations to this agreement shall not affect its terms; your signature shall be deemed an acceptance of its terms without modification. You further acknowledge that you have been advised of your right to consult with counsel in connection with this agreement.

          You have 21 days from your receipt of this agreement to consider it (a period which you may waive) before signing it and returning it to me. In addition, if you sign this agreement, you have seven days after signing it to revoke your release and waiver of claims under ADEA by notifying me, in writing. You understand that, in the event you revoke your release of claims under ADEA, DoubleClick will be relieved of its obligation to provide you the Separation Pay. Therefore, the promise to provide to you the Separation Pay will take effect eight days after you return this signed agreement (assuming you do not revoke your release of ADEA claims).

          To signify your acceptance of these terms, please sign and date this agreement in the space provided and return the original to me within 21 days.

          We wish you the best of success in your future endeavors.
