          (a) Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a list describing all inventions, original works of authorship, developments, improvements, and trade secrets which were made by me prior to my employment with the Company (each referred to as “Prior Invention”), which belong to me, which relate to the Company’s proposed business, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached.

Exhibit C — comScore Networks, Inc. Incentive Plan

COMSCORE NETWORKS, INC.

INCENTIVE PLAN

      1. Creation of Incentive Plan

          In order to encourage and reward certain officers, certain founders and key employees of comScore Networks, Inc. (the “Company”) for making efforts to increase company and stockholder value, remaining in the Company’s service, pursuing a potential change of control transaction, if appropriate, and/or transferring any personal goodwill relating to the Company, the Company’s Board of Directors (the “Board”) has resolved to create this Incentive Plan, as may be amended from time to time (the “Plan”). Any capitalized terms shall have the meaning set forth in this plan. The Plan is an incentive plan and is not subject to the Employee Retirement Income Security Act of 1974, as amended.

      2. Determination of Participants

          2.1 A portion of the payments under the Plan will be provided to certain predetermined individuals (or their affiliated entities) pursuant to Section 4.1 (the “Predetermined Participants”). The Predetermined Participants shall consist of the following: (i) partnerships or limited liability companies affiliated with Magid Abraham and Gian Fulgoni, (ii) all individuals employed by the Company at the time of a Liquidation Event (defined below) with titles and positions at least as senior as a Vice President of the Company and (iii) former employees of the Company (or their respective heirs) who, at the time of such employee’s separation from the Company, (x) were members of a select group of management or highly compensated employees and (y) were designated by the Company’s Chief Executive Officer as Participants.

          2.2 The Plan Committee (as defined in Section 8.3), in its sole discretion, may from time to time select any other officers and key employees eligible to participate in the Plan (the “Discretionary Participants”). The list of Discretionary Participants shall be set forth on Exhibit A hereto, which may be amended by the Plan Committee from time to time. The Plan Committee may select any or all of the Discretionary Participants at any time after the date of the adoption of this Plan until immediately prior to the consummation of a Liquidation Event. The Plan Committee may select Discretionary Participants who are also Predetermined Participants, such that those individuals (or their affiliated entities) may receive payments pursuant to Section 4.1 and Section 4.2 hereunder The Plan Committee, in its sole discretion, may select new Discretionary Participants or withdraw previously selected Discretionary Participants from the Plan. Together, the Predetermined Participants and the Discretionary Participants are the “Participants.”

          2.3 In addition to the condition specified in Section 2.1, it shall be a condition precedent to a Participant’s eligibility for a payment under the Plan that such Participant (or in the case of any Participants which are partnerships or limited liability companies affiliated with Magid Abraham and Gian Fulgoni. Magid Abraham and or Gian Fulgoni as natural persons) execute and ?????? revoke a waiver and release in favor of the Company in the form attached as Exhibit B hereto (a “Release”), all as provided in this Section 2.3. Prior to the distribution of any payments pursuant to

this plan the Company shall send by overnight courier or by hand delivery to each Participant a written notice describing the material terms of the Liquidation Event, at the address last shown on the records of the Company for such Participant (the “Transaction Notice”). A Participant may elect to share in the Potential Transaction Payment (as defined below), on the terms and conditions set forth in Plan, by notifying the Company of such election in writing and delivering to the Company an executed Release (such election and delivery, a “Plan Election”) by overnight courier or by hand delivery to the Company’s principal office. A Participant may make a Plan Election at any time prior to the distribution of any payments under this Plan. Any Participant who does not submit a Plan Election shall not be entitled to share in the Potential Transaction Payment hereunder and shall be deemed not to be a Participant hereunder. Furthermore, no Participant shall be eligible to receive any Liquidation Proceeds (as defined below) under this Plan unless and until he or she executes and delivers to the Company a participation notice in the form attached as Exhibit C hereto (a “participation Notice and Agreement”).

     3. Amount of Potential Transaction Payment

          3.1 The maximum amount of payments available, in the aggregate, under this Plan (the “Potential Transaction Payment”) shall be an amount up to 10% of any Liquidation Proceeds (as defined below).

          3.2 Subject to the terms of this Plan, the Potential Transaction Payment shall be paid to Participants in the same form of consideration as received by the Company’s stockholders in the Liquidation Event; provided that, the Company (or its acquirer or successor) may, in the sole discretion of the Board, attempt to provide that, to the extent reasonably practicable, payments shall be paid in the form of cash or readily tradable securities to the extent necessary to satisfy the tax obligations, of the Participants occurring by reason of their receipt of payments under this Plan, To the extent payments hereunder are paid in the same securities as received by the Company’s stockholders, the value of such securities for the purposes of payment of payments shall be determined in the same manner as the value of the Liquidation Proceeds is determined for purposes of calculating applicable liquidation preferences under Article IV. Section B(2)(d)(ii)the Company’s Amended and Restated Certificate of Incorporation (the “Restated Certificate”). Payments payable to a Participant hereunder shall be payable by the Company (or its acquiror or successor) and such payments are and, after the Liquidation Event, shall remain the liability and obligation of the Company (or its acquiror or successor).

      4. Participant Allocations

          4.1 Subject to the conditions precedent hereunder, as consideration for their services to and or personal goodwill relating to the Company, and subject to adjustment pursuant to Section 5.2 below, each Predetermined Participant shall receive a pro-rata share of the Liquidation Proceeds equal to the product of (i) 0.75 and (ii) the quotient of (x) the sum of (A) the number of shares of common stock held by such Predetermined Participant and (B) the number of Earned Options (as defined below) held by such Predetermined Participant and (y) the aggregate number of shares of common stock and Earned Options held by all Predetermined Participants (the “Predetermined Transaction Percentage”). Subject to adjustment pursuant to Section 5.2 below,

the aggregate Predetermined Transaction Percentage shall not exceed 75% of the Potentia Transaction Payment.

          4.2 Subject to the conditions precedent hereunder, as consideration for their services to and or personal goodwill relating to the Company and subject to adjustment pursuant to section 5.2 below, each Discretionary Participant shall receive a percentage of the Liquidation Proceeds as determined by the Plan Committee, in its sole discretion, from time to time (the “Discretionary Transaction Percentage”). Each Discretionary Participant’s Discretionary Transaction Percentages shall be as set forth opposite the name of such Discretionary Participant or Exhibit A hereto, as amended by the Plan Committee from time to time; provided that, subject to Section 5.2, the aggregate percentage of the Potential Transaction Payment allocated to the Discretionary Participants shall not exceed 25% (the “Maximum Aggregate Discretionary Percentage”) No later than the time of a Liquidation Event, the Maximum Aggregate Discretionary Percentage shall have been allocated by the Plan Committee. The Plan Committee, in its sole discretion, may increase or decrease each Discretionary Participant’s Discretionary Transaction Percentage, subject to the limit on the Maximum Aggregate Discretionary Percentage set forth above. Together, the Predetermined Transaction Percentages and the Discretionary Transaction Percentages are both “Transaction Percentages.”

          4.3 The Potential Transaction Payment shall be determined (in good faith by the Plan Committee) immediately after the Liquidation Date, unless the Liquidation Proceeds include Contingent Consideration. In such event, the portion of the Potential Transaction Payment not attributable to the Contingent Consideration (the “Non-Contingent Payment”) will be determined (in good faith by the Board) immediately after the Liquidation Date, and the portion of the Potential Transaction Payment attributable to the Contingent Consideration, and each Participant’s portion of the payment payment attributable to such Contingent Consideration, will be paid on a pro-rata basis to all Participants, in proportion to each Participant’s percentage of the Non-Contingent Payment.

      5. Amount of Participant Payment

          5.1 Provided that a Participant meets the eligibility requirements set forth in Section 2 and 4 of this Plan and this Plan has not been terminated, the payment amount for each Participant shall equal the sum of (a) the Fixed Amount (as defined below) and (b) the aggregate Variable Amounts (as defined below).

               (a) The “Fixed Amount” for a particular Participant shall equal (i) the individual Payment (as defined below) minus (ii) the value, as of the Liquidation Date, of the individual Payment for such Participant that is attributable to the Contingent Consideration set forth in the merger agreement or other agreements evidencing the Liquidation Event (if any).

               (b) Each “Variable Amount” for a particular Participant shall equal the individual Payment for such Participant that is attributable to the Contingent Consideration Amount (as defined below) set forth in the merger agreement or other agreements evidencing the Liquidation Event.

          5.2 The “Individual Payment” for a particular Participant shall equal the greater of zero and (i) the product of (x) the Potential Transaction Payment and (y) such Participant’s Transaction Percentage (the “Plan Proceeds”) minus (ii) amounts to be received by such Participant as a result of the exercise or cash-out of options to purchase the Company’s common stock issued pursuant to any incentive plan of the Company (net of any exercise price) or the ownership of the Company’s common stock originally purchased as common stock (the “Equity Proceeds”). For avoidance of doubt, to the extent that the Individual Payment as calculated hereby is negative for a particular Participant, such that the Equity Proceeds exceed the Plan Proceeds for such Participant. such Participant shall receive only the Equity Proceeds, but shall not owe the Company anything in respect of the negative Individual Payment. To the extent that Equity Proceeds are deducted from a particular Participant’s Individual Payment, the amount of such Equity Proceeds shall also be deducted from the aggregate Potential Transaction Payment; the amounts deducted shall not be redistributed among the other Participants. The Plan Committee in its good faith shall determine the amounts described in this Section 5, based on the values set forth in the merger agreement or other agreements evidencing the Liquidation Event.

     6. Payment Date

          Payments (less applicable tax withholdings) will be paid to each eligible Participant by the Company (or its acquiror or successor) as follows: (a) the Fixed Amount, if any, shall be paid within thirty (30) calendar days after the Liquidation Date and (b) each Variable Amount, if any, shall be paid within 30 days after the date of the actual payment of the corresponding Contingent Consideration Amount to the Company’s stockholders. No payments will be paid under this Plan if no Liquidation Event closes prior to the termination of this Plan.

      7. Excise Tax

          7.1 This Section 7 shall apply, as to a particular Participant, only if the Auditors (as defined below) determine that such Participant, on an after-tax basis, would receive more value under this Plan after the application of this Section 7 than before the application of this Section 7. For this purpose, “after-tax basis” shall mean a calculation taking into account all federal and state income and excise taxes imposed on the Participant, including (without limitation) the excise tax described in Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”). If this Section 7 is applicable, it shall supersede any conflicting provision of this Plan.

               (a) Basic Rule. The Company shall not make any payment or property transfer to, or for the benefit of, the Participant (under this Plan) that would subject the Participant to the excise tax described in Section 4999 of the Code. All calculations required by this Section 7 shall be attested to by the independent auditors retained by the Company most recently prior to the Liquidation Event (the “Auditors”), based on information supplied by the Company and the Participant, and shall be binding on the Company and the Participant. All fees and expenses of the Auditors shall be paid by the Company. Any proceeds not distributed to any Participants pursuant to section 7 shall be added to the Liquidation Proceeds which may be allocated to the Discretionary Participants by the Board pursuant to Section 4.2; provided that, the Board, in its sole descretion, may determine that any or all of such amounts may be deducted from the aggregate Potential Transaction Payment and not redistributed among the Participants.

               (b) Reductions. If the amount of the aggregate payments or property ??????fer to the Participant must be reduced under this Section 7, then the Participant shall direct in ??????ing which order the payments or transfers are to be reduced, but no change in the timing of any ??????ment or transfer shall be made without the Company’s written consent.

      8. Effective Date; Amendment/Termination of Plan
