     2.3 Exclusions to VSI/WSS License. Notwithstanding anything in this Agreement to the contrary, VSI/WSS expressly acknowledges and agrees that the VSI/WSS License granted under this Agreement does not permit VSI/WSS (or therefore any VSI/WSS Customers or VSI/WSS Providers) the right to:

(i) [ ^* ]; or

(ii) [ * ]; or

(iii) [ * ].

     2.4 Reservation of Rights.

          (i) Any and all rights not expressly granted to VSI/WSS in this Agreement with respect to the NetRatings Patents, including, without limitation, the rights reserved under Section 2.3 to practice the NetRatings Patents and the right to enforce the NetRatings Patents against third parties and collect royalties and/or damages in connection therewith, are hereby reserved and retained exclusively by NetRatings.

     2.5 Sublicense Rights

          (i) Sublicense Rights of VSI/WSS. As part of its rights under the VSI/WSS License, and only to the extent of such rights, VSI/WSS may grant to (1) VSI/WSS Customers a limited, non-exclusive, non-transferable, written sublicense under the VSI/WSS License solely for the purpose of allowing such entities to purchase or use the Licensed VSI/WSS Products and (2) VSI/WSS Providers a limited, non-exclusive, non-transferable, written sublicense under the VSI/WSS License solely for the purpose of allowing such entities to manufacture or develop any Licensed VSI/WSS Product for VSI/WSS, or offer for sale, sell, import, export, resell, license,

combine or distribute to VSI/WSS Customers any Licensed VSI/WSS Product whether on a standalone basis or in combination with its own products or services, including but not limited to, for the purpose of providing the Licensed VSI/WSS Product or any service depending thereon to a third party. Such sublicenses shall in no event apply to products, services or technology of a VSI/WSS Customer or VSI/WSS Provider which, without the Licensed VSI/WSS Product, infringes any independent claim of any NetRatings Patents. Other than as expressly provided by this Section 2.5(i), no other sublicenses of any kind may be granted by VSI/WSS under this Agreement, and any such sublicenses shall be null and void. Any sublicenses granted under this Section 2.5(i) are only valid and in effect when and if the VSI/WSS License is valid and in effect.

          (ii) Sublicense Rights of NetRatings. As part of its rights under the NetRatings License, and only to the extent of such rights, NetRatings may grant to (1) NetRatings Customers a limited, non-exclusive, non-transferable, written sublicense under the NetRatings License solely for the purpose of allowing such entities to purchase or use the Licensed NetRatings Products and (2) NetRatings Providers a limited, non-exclusive, non-transferable, written sublicense under the NetRatings License solely for the purpose of allowing such entities to manufacture or develop any Licensed NetRatings Product for NetRatings, or offer for sale, sell, import, export, resell, license, combine or distribute to NetRatings Customers any Licensed NetRatings Product whether on a standalone basis or in combination with its own products or services, including but not limited to, for the purpose of providing the Licensed NetRatings Product or any service depending thereon to a third party. Such sublicenses shall in no event apply to products, services or technology of a NetRatings Customer or NetRatings Provider which, which without the Licensed NetRatings Product, infringes any independent claim of any VSI/WSS Patents. Other than as expressly provided by this Section 2.5(ii), no other sublicenses of any kind may be granted by NetRatings under this Agreement, and any such sublicenses shall be null and void. Any sublicenses granted under this Section 2.5(ii) are only valid and in effect when and if the NetRatings License is valid and in effect.

     2.6 Markings and Samples. VSI/WSS and NetRatings shall each fully comply with the patent marking provisions of the United States or other applicable patent laws. In furtherance of the foregoing, VSI/WSS and NetRatings will clearly label their respective Licensed VSI/WSS Products and Licensed NetRatings Products with, in the case of Licensed VSI/WSS Products, identifying numbers of any issued NetRatings Patents, specifying that the Licensed VSI/WSS Products are licensed under such NetRatings Patents, and in the case of Licensed NetRatings Products, identifying numbers of any issued VSI/WSS Patents, specifying that the Licensed NetRatings Products are licensed under such VSI/WSS Patents. As may be requested from time to time, but in no event more than once each calendar year of the Term, VSI/WSS and NetRatings shall submit to each other five (5) samples of each of their respective Licensed VSI/WSS Products and Licensed NetRatings Products, or such other evidence, including screen captures, as will be reasonably sufficient to show that the marking requirements of this Section 2.6 are being fulfilled. The marking of any Licensed VSI/WSS Product or Licensed NetRatings Product pursuant to this Agreement shall not be deemed to constitute an admission by VSI/WSS or NetRatings that their respective Licensed VSI/WSS Products and Licensed NetRatings Products are covered by either the NetRatings Patents or the VSI/WSS Patents, as the case may be.

3. PAYMENT OF ROYALTIES

     3.1 Royalty Fees for VSI/WSS License.

          (i) Initial Royalty. As partial consideration for the settlement of the New York and California Actions and the VSI/WSS License granted under this Agreement, and regardless of whether any additional payments are paid under Section 3.1 of this Agreement, VSI/WSS shall pay nine-million U.S. dollars ($9,000,000) to NetRatings (the “Initial Royalty”) as follows: (1) within five (5) business days from the date on which VSI/WSS executes this Agreement and receives a copy of this Agreement that has been fully executed by a duly authorized representative of NetRatings, VSI/WSS shall pay two-million U.S. dollars ($2,000,000) to NetRatings; and (2) commencing on March 31, 2008, and continuing thereafter on the last day of each calendar quarter through and including June 30, 2011, VSI/WSS shall pay five-hundred thousand U.S. dollars ($500,000) to NetRatings, for a total of seven-million U.S. dollars ($7,000,000) in quarterly payments. Notwithstanding the foregoing, in the event of a VSI/WSS Change of Control Event the final four quarterly payments provided for under Section 3.1(i)(2), totaling two-million U.S. dollars ($2,000,000), will be accelerated and will become immediately due and payable by VSI/WSS to NetRatings as of the effective date of the VSI/WSS Change of Control Event (the “Accelerated Initial Royalty”). VSI/WSS shall pay the Accelerated Initial Royalty within fifteen (15) business days of the VSI/WSS Change of Control Event and shall continue making the quarterly payments provided under Section 3.1(i)(2) until a total of seven-million U.S. dollars ($7,000,000) in such quarterly payments (including the Accelerated Initial Royalty) has been paid by VSI/WSS to NetRatings.

          (ii) Additional Royalty. As further consideration for the VSI/WSS License granted under this Agreement, and in addition to the other payments required pursuant to Section 3.1 of this Agreement, VSI/WSS will pay to NetRatings an additional royalty, in the aggregate amount of two-million two-hundred fifty-thousand U.S. dollars ($2,250,000) (the “Additional Royalty”), which Additional Royalty shall be required to be paid within fifteen (15) business days of the occurrence of a VSI/WSS Change of Control Event, provided that such Additional Royalty will only be payable in connection with the first VSI/WSS Change of Control Event to occur following the Effective Date.

          (iii) VSI/WSS Acquisition Royalties. As further consideration for the VSI/WSS License granted under this Agreement, and in addition to the other payments required pursuant to Section 3.1 of this Agreement, in the event that, during the Term, VSI/WSS (or a wholly owned subsidiary formed in connection with such acquisition transaction) acquires, whether by merger, asset purchase, consolidation, reorganization, or other similar transaction or series of transactions, (a) all or substantially all the technology, customers, or other assets of an entity, (b) fifty percent (50%) or more of the combined voting power of an entity’s then outstanding securities or (c) all or substantially all of the Web Analytics assets of an entity (in any case, the entity or assets so acquired being referred to herein as the “VSI/WSS Acquired Entity” and the transaction by which the entity or assets are so acquired being referred to herein as the “VSI/WSS Acquisition”), then, if VSI/WSS elects to have any of such VSI/WSS Acquired Entity’s products, services or technology considered Licensed VSI/WSS Products pursuant to Section 16.1 of this Agreement as of and from the date of any such transaction, then within thirty (30) business days following the closing date of any such transaction VSI/WSS will: (1) if the

acquisition is of a VSI/WSS Acquired Entity listed in Schedule C to this Agreement, pay NetRatings an additional royalty of [ ^* ] percent [ ^* ] of the Revenues of such VSI/WSS Acquired Entity generated from Web Analytics products, services and technologies and recognized by such VSI/WSS Acquired Entity within the four most recently completed calendar quarters preceding the closing of such acquisition; or (2) if the acquisition is of a VSI/WSS Acquired Entity not listed in Schedule C, pay an additional royalty of [ * ] percent [ * ] of the Revenues of such VSI/WSS Acquired Entity generated from Web Analytics products, services and technologies and recognized by such VSI/WSS Acquired Entity within the four most recently completed calendar quarters preceding the closing of such acquisition (either of the foregoing royalties referred to as a “VSI/WSS Acquisition Royalty”). Upon payment of a VSI/WSS Acquisition Royalty by VSI/WSS (or if no VSI/WSS Acquisition Royalty need be paid by VSI/WSS as a result of the provisions of Section 3.1(iv)), NetRatings shall immediately provide a release (consistent with Section 7.1) of VSI/WSS and the VSI/WSS Acquired Entity for all actions, claims, demands, causes of action, charges, judgments, damages and attorneys fees from the beginning of time up to and including the date of any such transaction relating to the VSI/WSS Acquired Entity’s products, services, or technology; provided, however, that if the VSI/WSS Acquired Entity is an entity listed on Schedule C to this Agreement or is a party to litigation with NetRatings based on a claim of infringing any NetRatings Patent as of the date of the announcement of a transaction (any such entity, a “Designated Acquired Entity”), then, unless no Acquisition Release Royalty need be paid by VSI/WSS as a result of the provisions of Section 3.1(iv), the Acquisition Release Royalty set forth in Section 3.1(v) would be required to be paid to NetRatings in addition to the VSI/WSS Acquisition Royalty in order for VSI/WSS and such Designated Acquired Entity to receive any such release.

          (iv) For purposes of Section 3.1(iii), the “Revenues” of the products, services, or technology for any such VSI/WSS Acquired Entity (and any Designated Acquired Entity) shall be counted as defined in Section 1.9 of this Agreement, but shall be limited to Revenues generated from Web Analytics products, services or technologies. Notwithstanding the foregoing and Section 3.1(v) below, VSI/WSS need not pay the VSI/WSS Acquisition Royalties nor the Acquisition Release Royalties for any transaction (and VSI/WSS and the VSI/WSS Acquired Entity (including any Designated Acquired Entity) shall be deemed licensed and released pursuant to Sections 3.1(iii) and 3.1(v) as though such royalties had been paid), if and only if (1) VSI/WSS has paid (regardless of the type of consideration) less than [ * ] for such VSI/WSS Acquired Entity (including any Designated Acquired Entity) or the assets or securities thereof in a single transaction or in any series of related transactions, (2) the VSI/WSS Acquired Entity (including any Designated Acquired Entity) already has a license from NetRatings under the NetRatings Patents which covers the acquired technology, customers or other assets of the VSI/WSS Acquired Entity (including any Designed Acquired Entity); provided, however, that any payments due to NetRatings under a license agreement between NetRatings and the VSI/WSS Acquired Entity (including any Designated Acquired Entity) will still be due and payable in accordance with the terms of such license agreement, or (3) VSI/WSS’s royalty payment obligations have terminated prior to the closing date of such transaction pursuant to

Section 3.2. For the avoidance of doubt, an acquisition by VSI/WSS under Section 3.1(iii) cannot also be deemed a VSI/WSS Change of Control Event.

          (v) Acquisition Release Royalties for Designated Acquired Entities. In the event that, during the Term, VSI/WSS acquires, whether by merger, asset purchase, consolidation, reorganization, or other similar transaction or series of related transactions, (a) all or substantially all of the technology, customers, or other assets of a Designated Acquired Entity, (b) fifty percent (50%) or more of the combined voting power of a Designated Acquired Entity’s then outstanding securities, or (c) all or substantially all of the Web Analytics products, services or technology of a Designated Acquired Entity, then, at VSI/WSS’s election, in exchange for a release (consistent with Section 7.1) of VSI/WSS and the Designated Acquired Entity by NetRatings for all actions, claims, demands, causes of action, charges, judgments, damages and attorneys fees relating to such Designated Acquired Entity’s products, services, or technology from the beginning of time up to and including the date of any such transaction, within thirty (30) business days following the closing date of any such transaction, VSI/WSS will pay NetRatings an additional royalty of [ ^* ] of the Revenues of such Designated Acquired Entity recognized by such Designated Acquired Entity within the four most recently completed calendar quarters preceding the closing of such acquisition for all Web Analytics products, services, or technology sold, leased, licensed or otherwise distributed by such Designated Acquired Entity during such period (the foregoing royalties referred to as an “Acquisition Release Royalty”). Upon payment of an Acquisition Release Royalty by VSI/WSS (or if no Acquisition Release Royalty need be paid by VSI/WSS as a result of the provisions of Section 3.1(iv)), NetRatings shall immediately provide such release to VSI/WSS and such Designated Acquired Entity.

     3.2 Termination of VSI/WSS Royalty Obligations. In the event that, and only in the event that, every claim of every one of the NetRatings Patents is determined to be invalid or unenforceable by a final, unappealable decision of a court having competent jurisdiction and authority to issue such a holding or by the Federal Circuit Court of Appeals, whichever is earlier, then the payment obligations set forth in Section 3.1 shall be terminated as of the date of such decision, and from that date forward, no further Initial Royalty (including any Accelerated Initial Royalty), Additional Royalty, VSI/WSS Acquisition Royalty or Acquisition Release Royalty payments will be due. The termination of the payments pursuant to this Section 3.2 shall not entitle VSI/WSS to a refund of any payments previously made.

     3.3 No Contest.

          (iv) VSI/WSS shall provide written notice of its intent to assign this Agreement to a VSI/WSS Purchaser upon or following a VSI/WSS Change of Control Event prior to or concurrently with the effective date of the assignment.

obligations hereunder, including without limitation the VSI/WSS License, to any third party (other than to an Affiliate) without the prior express written approval of NetRatings; provided that VSI/WSS may assign this Agreement to an Affiliate without any such approval.

The provisions of the Agreement shall be binding upon and shall inure to the benefit of the Parties hereto, their heirs, administrators, successors and assigns, but only to the extent permitted under this Section 15. For avoidance of doubt, in connection with each successive assignment permitted under this Section 15, the assignee of this Agreement, including without limitation the VSI/WSS License, shall enjoy all the rights and benefits of, and shall be subject to all of the obligations of, VSI/WSS under this Agreement, and all references to VSI/WSS in this Agreement shall be deemed to refer to such assignee from and after each such assignment.

If VSI/WSS does not timely pay NetRatings the required VSI/WSS Acquisition Royalties, if any, and timely provide the Section 3.6 royalty statement, then the VSI/WSS License granted in this Agreement shall not extend to any products, services, or technology developed, created or offered by the VSI/WSS Acquired Entity, including to the extent any products, services or technology developed, created or offered by the

VSI/WSS Acquired Entity are incorporated into any of the Licensed VSI/WSS Products, until such time as such required VSI/WSS Acquisition Royalties, if any, are paid, and such Section 3.6 royalty statements are provided, to NetRatings. Nothing in this Section 16 or otherwise shall preclude VSI/WSS from combining, merging, bundling or incorporating any unlicensed product, service or technology into or with a Licensed VSI/WSS Product (or any portion thereof) if such unlicensed product, service or technology does not, by itself, infringe any claim of any NetRatings Patent, and the license granted in this Agreement shall continue to extend to such Licensed VSI/WSS Product notwithstanding any such combining, merging, bundling or incorporating.

     16.2 For the avoidance of doubt, in the event VSI/WSS acquires a VSI/WSS Acquired Entity or the products, services, technology, customers or other assets thereof pursuant to Section 3.1(iii), and VSI/WSS is not obligated to pay the VSI/WSS Acquisition Royalties for one or more of the reasons set forth in Section 3.1(iii) or (iv), then the VSI/WSS Acquired Entity’s Web Analytics products, services or technology will be considered Licensed VSI/WSS Products under this Agreement as of the effective date of the acquisition.

     16.3 VSI/WSS’s election not to obtain a license and/or release for an acquisition pursuant to Section 3.1(iii) or (v) by paying the VSI/WSS Acquisition Royalty and/or Acquisition Release Royalty and subsequent use or sale of unlicensed products shall not be deemed a breach of this Agreement.

18. SEVERABILITY

     If any term, clause or provision hereof is held invalid or unenforceable by a court of competent jurisdiction, such invalidity shall not affect the validity or operation of any other term, clause or provision and such invalid term, clause or provision shall be deemed to be severed from the Agreement.

19. COUNTERPARTS

22. ENTIRE AGREEMENT; AMENDMENT

     This Agreement constitutes the entire understanding of the Parties, and revokes and supersedes all prior agreements between the Parties and is intended as a final expression of their agreement. For the avoidance of doubt, the Virginia Action Agreement shall remain in full force and effect; provided, however, that in the event of any conflict between this Agreement and the Virginia Action Agreement, this Agreement shall control. Each of VSI/WSS and NetRatings acknowledges and agrees that such party is not currently aware of any such conflict. Notwithstanding and without limitation of the foregoing, nothing in this Agreement is intended nor shall be deemed to void the payment obligations of VSTLLC to NetRatings under Section 3.1(i) and 3.1(ii) of the Virginia Action Agreement. All negotiations and representations made prior to the execution of this Agreement shall be deemed to have been integrated into the terms and conditions of this Agreement. This Agreement shall not be modified or amended except in writing signed by the Parties hereto and specifically referring to this Agreement.

Statements in this press release that are not a description of historical facts are forward-looking statements.

At least once during each calendar year of the Term, Licensee shall submit to NetRatings one sample of each of the foregoing items to be marked sufficient to show that the marking requirements of this Section 2.6 are being fulfilled. Neither the marking of any Licensed Product pursuant to this Agreement or this Section shall be deemed to constitute an admission by Licensee that the Licensed Products are covered by the NetRatings Patents.

3. PAYMENT OF ROYALTIES

     3.1 Royalty Fees.

          (i) As partial consideration for the settlement of the Action and the License granted under this Agreement, and in addition to any payments that may be required under Section 3.1(ii) of this Agreement, Licensee shall pay one-million U.S. dollars ($1,000,000) to NetRatings (the “Initial Royalty”). The Initial Royalty shall be deemed immediately owing to NetRatings as of the Effective Date. Notwithstanding the foregoing, and as an accommodation to Licensee, NetRatings shall accept payment of the Initial Royalty in the following manner: (1) within five (5) business days from the date on which Licensee executes this Agreement and receives an original of this Agreement, including all Exhibits, that has been executed by a duly authorized representative of NetRatings, Licensee shall pay one-hundred thousand U.S. dollars ($100,000) to NetRatings, (2) on or before December 16, 2005, Licensee shall pay one-hundred thousand U.S. dollars ($100,000) to NetRatings, and (3) for the calendar quarter commencing January 2006, and continuing therefrom until a total of 40 payments equaling eight-hundred thousand U.S. dollars ($800,000) have been made, within fifteen (15) days following the end of each calendar quarter, Licensee shall pay twenty-thousand U.S. dollars ($20,000) to NetRatings. After the payments required under this Section 3.1(i) have been paid in full, no further royalty fees will be due under this Section 3.1(i).

NetRatings: ____

Licensee: _____

          (ii) As further consideration for the License granted under this Agreement, and in addition to the payments of the Initial Royalty required pursuant to Section 3.1(i) of this Agreement, Licensee will pay NetRatings an additional royalty of up to one million U.S. dollars ($1,000,000) (the “Additional Royalty”) as follows: (i) for each calendar year in which Licensee’s Revenue reaches at least [ ^* ], Licensee will pay NetRatings [ * ]; (ii) for each calendar year in which Licensee’s Revenue exceeds [ * ], Licensee will pay NetRatings [ * ]; and (iii) for each calendar year in which Licensee’s Revenue exceeds [ * ], Licensee will pay NetRatings [ * ]. The Additional Royalty shall be calculated and paid to NetRatings by Licensee at Licensee’s sole expense on a yearly basis within thirty (30) days following the end of each calendar year (each a “Royalty Period”) during the Term. Licensee’s obligation to pay the Additional Royalty on a yearly basis during the Term of this Agreement will terminate when the total amount of Additional Royalty fees paid by Licensee to NetRatings pursuant to this Section 3.1(ii) reaches one million U.S. dollars ($1,000,000), after which time the payments required under this Section 3.1(ii) shall be deemed to be paid in full, and no further royalty fees will be due under this Section 3.1(ii).

          (iii) Termination of Additional Royalty Obligations. In the event that, and only in the event that, every claim of every one of the NetRatings Patents is held to be invalid and/or unenforceable against all persons or entities by a final, non-appealable decision of a court having competent jurisdiction and authority to issue such a holding, then the Additional Royalty shall terminate as of the date of such final, non-appealable decision. From that date forward, no Additional Royalty payments will be due. The termination of the Additional Royalty payments pursuant to this Section 3.1(iii) shall not entitle Licensee to a refund of any payments previously made. For the avoidance of any doubt, this Section 3.1(iii) does not and shall not be construed to affect the payment of the Initial Royalty required under Section 3.1(i) of this Agreement and the Initial Royalty is due and payable as of the Effective Date irrespective of any subsequent event, including any holding as to the validity or unenforceability of the NetRatings Patents.

     3.2 Method of Payment. Unless otherwise specified in writing by NetRatings, all payments to be made by Licensee under this Agreement shall be made by wire transfer of funds to the account of NetRatings as set forth in Exhibit B hereto.

     3.3 Interest on Late Payments. Late payments shall incur interest at the rate of One Percent (1%) per month from the date such payments were originally due hereunder.

     3.4 Royalty Statements. Simultaneously with the making of any of the Additional Royalty payments which may be required under Section 3.1(ii) of this Agreement, Licensee shall provide NetRatings with a written statement in the form attached as Exhibit C hereto indicating the basis for the calculation of such Additional Royalty payments. Such royalty statements shall be certified as accurate by a duly authorized officer of Licensee. Such statements shall be

NetRatings: ____

Licensee: _____

furnished to NetRatings regardless of whether any Licensed Products are sold or provided during the Royalty Period or whether any actual Additional Royalty payments were owed. The receipt or acceptance by NetRatings of any royalty statement or Additional Royalty payment shall not prevent NetRatings from subsequently challenging the validity or accuracy of such statement or Additional Royalty payment.

4. RECORD INSPECTION AND AUDIT

     4.1 Right To Inspect and Audit. NetRatings shall have the right, upon reasonable notice to Licensee, such reasonable notice not to be less than thirty (30) days, up to one (1) time during each calendar year during the Term and for three (3) years thereafter, to have a designated independent accounting firm that is mutually agreed upon by NetRatings and Licensee inspect Licensee’s books and records and all other documents and materials in Licensee’s possession or control as such designated independent accounting firm deems necessary for the sole purpose of verifying the contents of all royalty statements and in order to conform the basis and accuracy of Additional Royalty payments for all Licensed Products. Such designated independent accounting firm must agree in writing to maintain the confidentiality of such books and records, including an obligation not to disclose any information from such books and records to NetRatings.

     4.2 Underpayments. In the event that an inspection of books and records pursuant to Section 4.1 reveals an underpayment by Licensee of Additional Royalty payments under this Agreement, Licensee shall immediately pay NetRatings the difference between the amounts actually paid and the amounts required to be paid under this Agreement, plus interest calculated at the rate of One Percent (1%) per month. If such underpayment is in excess of Ten Percent (10%) less than the required Additional Royalty payment during any Royalty Period, Licensee shall also reimburse NetRatings for the cost of such inspection, including reasonable costs of retaining the accounting firm referenced in Section 4.1.

5. REPRESENTATIONS AND WARRANTIES

     5.1 Representations of NetRatings.
