Section 3.02. Without limiting the generality of the provisions of Article II of this Agreement, and notwithstanding anything therein to the contrary, each of the parties hereto acknowledges, recognizes and agrees that, after the Distribution, ACNielsen shall own all right, title and interest in, to and under those patents and patent applications identified in Schedule C, together with all Intellectual Property related thereto and associated therewith, for the exclusive use and benefit of ACNielsen in connection with the ACNielsen Business as it is now or may hereafter be conducted anywhere in the world. Section 3.03. Notwithstanding the provisions of Article II of this Agreement, each of the Parties hereto acknowledges, recognizes and agrees that NCH Promotional Services, Inc., shall own all right, title and interest in, to and under those patents identified in Schedule D, together with all Intellectual Property related thereto and associated therewith, for the exclusive use and benefit of NCH Promotional 6 Services, Inc., in connection with its business as it is now or may hereafter be conducted anywhere in the world. TRADEMARKS AND TRADEMARK APPLICATIONS Section 3.04. Notwithstanding the provisions of Article II of this Agreement, each of the Parties hereto acknowledges, recognizes and agrees that, after the Distribution, Cognizant shall own all right, title and interest in, to and under those trademarks, service marks, registrations and applications therefor identified in Schedule E, together with all goodwill and Intellectual Property related thereto and associated therewith, for the exclusive use of Cognizant in connection with the Cognizant Business as it is now or may hereafter be conducted anywhere in the world. Section 3.05. Without limiting the generality of the provisions of Article II of this Agreement, and notwithstanding anything therein to the contrary, each of the Parties hereto acknowledges, recognizes and agrees that, after the Distribution, ACNielsen shall own all right, title and interest in, to and under those trademarks, service marks, registrations and applications therefor identified in Schedule F, together with all goodwill and Intellectual Property related thereto and associated therewith, for the exclusive use of ACNielsen in connection with the ACNielsen Business as it is now or may hereafter be conducted anywhere in the world.

Section 3.07. Notwithstanding the provisions of Article II of this Agreement, each of the Parties hereto acknowledges, recognizes and agrees that, after the Distribution, all right, title and interest in, to and under those trademarks, service marks, registrations and applications therefor identified in Schedule H, together with all goodwill and Intellectual Property related thereto and associated therewith, shall be owned by the LLC, which shall have sole responsibility for maintaining and preserving the quality of those trademarks, service marks, registrations and applications therefor in a manner consistent with the high standards and reputation for quality associated with the "NIELSEN" name. The LLC will be organized and governed according to the LLC Agreement, substantially in the form of Schedule I and as it may be amended or modified by Cognizant and ACNielsen pursuant to its terms, with the fundamental purpose at 6 all times of assisting both Cognizant and ACNielsen in achieving their legitimate business purposes to the greatest extent possible while also preserving the integrity of the trademarks, service marks, registrations and applications therefor owned by the LLC and minimizing the risk of confusion to any relevant group of consumers for any product or service associated with any such trademark, service mark, registration or application therefor. Schedule H also identifies those trademark and service mark applications that may not be immediately transferred or assigned to the LLC under the law prevailing in the relevant jurisdiction. Legal ownership of each such application shall be retained by ACNielsen for the benefit of the LLC pursuant to an escrow agreement until such application is granted; at which time the registration and all goodwill and Intellectual Property related thereto and associated therewith, if any, shall be transferred to the LLC, as shall be specified in both the LLC Agreement and the pertinent escrow agreement. If either Cognizant or ACNielsen desires to use, register and/or apply for registration of any trademark or service mark incorporating, referring to or derived from the "NIELSEN" name or "split-N" symbol in any country or with any authority where no such trademark or service mark has previously been used, registered or applied for, the party desiring to make such use, registration or application shall cause the LLC to determine, by obtaining the advice of counsel with expertise in the law prevailing in the relevant jurisdiction, whether that country or authority is an Associated Marks Country (as defined in the LLC Agreement) before making any such use, registration or application. That party shall not use, register or apply for any such trademark or service mark unless and until the LLC has determined that the country or authority in question is not an Associated Marks Country, or if it is determined to be an Associated Marks Country, shall proceed with the use, registration or application of such trademark or service mark only as a Common Heritage Trademark as defined in and subject to the LLC Agreement. Section 3.08. Reversion of Certain Property. Schedule H also identifies certain trademarks and service marks incorporating, referring to or derived from the "NIELSEN" name or "split-N" symbol that shall be distributed, together with all goodwill and Intellectual Property related thereto and associated therewith, by the LLC to either Cognizant or ACNielsen as indicated therein and to the extent appropriate under the LLC Agreement, in the event that the relevant local law pursuant to which rights in such trademarks or service marks are granted should subsequently, in the opinion of counsel to the LLC with expertise in the relevant local law, both (a) permit the ownership of such trademarks or service marks by unrelated entities without substantial jeopardy to their validity or enforceability, and (b) not present a substantial likelihood of denial for any future application for registration of such trademarks or service marks, if applications for concurrent registration of such trademarks or service marks for similar goods or services or for goods or services in the same class were 8 to be made by unrelated entities. In no event, however, shall any trademark or service mark consisting of the "NIELSEN" name or the "split-N" symbol, standing alone, be so distributed, for so long as both Cognizant and ACNielsen shall continue to use any trademark or service mark anywhere in the world incorporating, referring to or derived from the "NIELSEN" name. Section 3.09. Clear Identification of Source. Cognizant and ACNielsen agree that, subsequent to the Distribution Date, neither Cognizant nor ACNielsen shall possess or acquire any right to use the "NIELSEN" name or "split-N" symbol standing alone or by itself in any manner for any purpose, including use of the name as an Internet domain name or the equivalent or as the name or logo for a business, corporation, or other legal entity, except as may otherwise be agreed by and between Cognizant and ACNielsen; provided, however, that both Cognizant and ACNielsen may continue to use the "NIELSEN" name or "split-N" symbol in any usage for which each, respectively, is currently using the name or symbol, including usage of the name as part of electronic mail or messaging addresses for its employees using existing systems, during a transitional period of six months subsequent to the Distribution Date or under the circumstances specified in Section 2.14(b)(iii) of the Distribution Agreement (a "Transitional Use"). Subsequent to the Distribution Date, except for a Transitional Use, any use that Cognizant or ACNielsen may make of the "NIELSEN" name or "split- N" symbol for any business purpose, including any use in trade, advertising, publicity, packaging, or labeling, and including any use of any trademark or service mark identified in Schedule H or in Schedules E and F that incorporates, refers to, or is derived from the "NIELSEN" name or "split-N" symbol, shall only be made in conjunction with other words, names, symbols or logos prominently displayed in as near proximity thereto as is reasonably feasible and, at minimum, on the same page, panel, sheet or screen therewith, clearly identifying the source of the communication, good or service: (a) with regard to Cognizant, as "NIELSEN TV," "NIELSEN MEDIA," "NIELSEN MEDIA RESEARCH," or another entity using a name not incorporating, referring to, or derived from the "NIELSEN" name; and (b) with regard to ACNielsen, as "ACNIELSEN," "A.C. NIELSEN," or another entity using a name not incorporating, referring to, or derived from the "NIELSEN" name. In addition, in the event that ACNielsen enters into any television audience measurement business in the United States or Canada subsequent to the Distribution Date, its use of any name incorporating, referring to, or derived from the "NIELSEN" name in connection with such business shall be subject to the provisions of Schedule J. Section 3.10. Limitations on Concurrent Use. The provisions in this Article shall in no way restrict the rights of Cognizant or ACNielsen to sell any product or service or enter into any business identical or similar to any product or service sold, or business conducted by, the other before or after the Distribution Date. Cognizant and ACNielsen agree, however, that 9 in the event that either Cognizant or ACNielsen sells any product or service, or enters into any business, after the Distribution Date in any country that is identical or substantially similar to those sold or conducted by the other in that country prior to the Distribution Date, the second party desiring to sell such a similar product or service or desiring to enter such a similar business shall not use any name incorporating, referring to or derived from the "NIELSEN" name or the "split-N" symbol to describe or identify such product, service, or business; provided that any product, service or business relating to the measurement of Internet usage or to research and analysis of Internet usage, utilization, advertising, or purchasing patterns, by businesses or consumers, shall not be subject to such restriction and shall only be subject to the restrictions set forth in Section 3.09, and provided further that any product or service that may in future be sold by ACNielsen in connection with any television audience measurement business in the United States or Canada shall be subject to both this restriction and the provisions of Schedule J. Cognizant and ACNielsen further agree that any future use of any Common Heritage Trademark (as defined in the LLC Agreement) shall only be made by or pursuant to license from the LLC. Section 3.11. Clear Fields. Cognizant and ACNielsen agree that, subsequent to the Distribution Date, neither Cognizant nor ACNielsen shall use as a trademark or service mark (except pursuant to license), register or attempt to register any trademark or service mark (whether registered or not) that has been used (except pursuant to license), owned or applied for by the other in any country or geographic area as of the Distribution Date, including but not limited to those trademarks and service marks identified in Schedules A, F, G and H, in either that country or geographic area or in any other country or geographic area. This provision shall not apply to the "MIDAS" trademark used and/or registered by ACNielsen in Germany, the "MIDAS" trademarks or service marks used and/or registered by IMS (Cognizant) in Germany and elsewhere, the "PRIZMA" trademark used and/or registered by IMS (Cognizant) in Greece, the "PRISMA FOLDER" trademark used and/or registered in the Benelux countries by ACNielsen, the "NIELSEN PRISMA" trademark used and/or registered in Germany by ACNielsen, the "PROMOTRAK" trademark or service mark used and/or registered by IMS (Cognizant) in the United States, or the "PROMOTRACK" name and/or trademark or service mark used and/or registered by ACNielsen elsewhere in the world. With regard to these specific items, each party shall retain and have such rights with respect to such items that it would otherwise have or become entitled to under the laws of any relevant jurisdiction in the absence of this provision. Section 3.12. Notice and Publicity. Prior to or subsequent to the Distribution, both Cognizant and ACNielsen agree to give or cause to be given, in each distinct geographic area or line of business in which they intend to operate or to sell any product or service, such notice and publicity of their 10 separation and distinct identities as the source of any such business, product or service as may be reasonable under the circumstances or required by the relevant local law, where the local law imposes such a duty so to notify and/or publicize. Section 3.13. Internet Hyperlinks. Cognizant and ACNielsen agree to assign and transfer all rights in the existing "nielsen.com" Internet domain name to the LLC, and to cause the LLC to provide and maintain an Internet or Web site using that domain name for the purpose of providing and maintaining "hyperlinks" to the principal Internet or Web sites maintained by both Cognizant and ACNielsen. In addition, both Cognizant and ACNielsen agree to provide and maintain in any Internet or Web site maintained by Cognizant or ACNielsen, respectively, for a period of two (2) years subsequent to the Distribution Date, a hyperlink to the principal Internet or Web site maintained by the other. All such hyperlinks shall be displayed together with appropriate text indicating the nature and purpose of the hyperlink and describing in summary the separation and distinct identities of each as sources of their respective goods and services. Cognizant and ACNielsen further agree to cooperate reasonably in the identification of appropriate addresses and/or domain names and in resolving technical issues necessary to provide and maintain such hyperlinks. Section 3.14. Assignments and Sublicenses; Remedies for Improper Use. Cognizant and ACNielsen agree that any form of transfer of, or grant of rights in or to, any trademark or service mark (whether registered or not) incorporating, referring to or derived from the "NIELSEN" name or "split-N" symbol (including, but not limited to, all rights received by either Cognizant or ACNielsen pursuant to license from the LLC) by either Cognizant or ACNielsen (the "Granting Party") to a non- party to this Agreement shall be made explicitly subject to all pertinent provisions of Article III of this Agreement concerning the Granting Party's own use of any such trademark or service mark, and notice shall be given by the Granting Party to the Party other than the Granting Party (the "Interested Party") of any such transfer or grant of rights. Any such grant of rights that is not an outright transfer, assignment, sale or disposition of all of the Granting Party's rights and interests in any such trademark or service mark, including any sub-license, consent or permission to use, to a non-party to this Agreement (a "Grantee") shall be pursuant to a written instrument that shall both (a) explicitly bind the Grantee to all pertinent provisions of this Agreement restricting the Granting Party's own use of any such trademark or service mark, and (b) explicitly provide that the Granting Party may revoke the grant of rights, in its sole discretion, upon not more than thirty days' notice to the Grantee. It shall be the obligation of the Granting Party to use its best efforts to police the use made of any such trademark or service mark by a Grantee. If the Granting Party reasonably believes that a Grantee is using any such trademark or service mark in a manner that is (c) inconsistent with the terms of this 11 Agreement or (d) injurious to the high standards and reputation for quality associated with the "NIELSEN" name (an "Improper Use"), the Granting Party shall promptly so notify both the Grantee and the Interested Party. If the Grantee does not thereafter correct or terminate the Improper Use within thirty days, the Granting Party shall revoke the grant of rights to the Grantee, and shall give notice thereof to the Interested Party. If the Interested Party reasonably believes that the use made by a Grantee of rights granted by the Granting Party is an Improper Use, it may so notify the Granting Party, which shall thereupon take appropriate measures to investigate the use in question and shall notify the Interested Party within fourteen (14) days as to whether it also reasonably believes that the Grantee is engaging in an Improper Use. If the Granting Party, after receiving notice from the Interested Party, also reasonably believes that the Grantee is engaging in an Improper Use, it shall take all appropriate measures to correct or terminate the Improper Use, including the giving of notice of revocation to the Grantee, if necessary. If the Granting Party (x) gives notice to the Interested Party that it does not reasonably believe that a Grantee is engaging in an Improper Use, or (y) fails to take appropriate measures to correct or terminate an Improper Use after giving notice to the Interested Party that it reasonably believes a Grantee is engaging in an Improper Use, or (z) is unable to correct or terminate an Improper Use by a Grantee within sixty (60) days of the first notice of suspected Improper Use given by either the Granting Party or the Interested Party, the Interested Party may both commence any action or proceeding at law or equity that it believes it has an appropriate and independent basis to assert against the Grantee and invoke its contractual rights against the Granting Party in the event of an Intellectual Property Dispute as defined in this Agreement. Section 3.15. Duty to Avoid Confusion. The Parties hereto confirm their belief that likelihood of confusion will not result from the Parties' use of their respective trademarks and service marks as provided for in this Agreement, due to the differences in the environments in which and the customers to whom the goods and services of the Parties associated therewith are primarily offered and sold. The Parties further believe that any potential future confusion will be prevented under the terms of this Agreement. Furthermore, in order to enable and permit each other to continue using and to register their respective trademarks and service marks and to ensure that there is no confusion in any relevant marketplace between them, the Parties agree to use their best efforts to avoid actual or potential confusion arising from their use, to advise any other affected Party of any instance of actual or potential confusion that comes to a Party's attention concerning use of their respective trademarks and service marks, to take all such steps as may be appropriate and necessary to remedy any actual or potential confusion caused by their actions, and to cooperate with each other in good faith to avoid and prevent actual or potential confusion. 12 Section 3.16. Consent to Registration. Subject to the other provisions of this Article, each Party agrees that any other Party may use a copy of this Agreement to evidence the other Party's express consent to registration of the Party's trademarks or service marks, if necessary to obtain or maintain a registration of such mark in the United States Patent and Trademark Office or any other pertinent governmental agency in any country or group of countries; and further agrees to take any other necessary action that any other Party may reasonably request to express or confirm such consent. Section 3.17. Transfer at or Prior to Distribution. The Parties agree to execute all such documents, and to take all such actions, prior to or at the Distribution as they may deem to be necessary to achieve or confirm the respective ownership of rights in the Nielsen Intellectual Property as contemplated in this Article to be effective upon the Distribution Date. Section 3.18. Construction. In the event of any inconsistency between Article III and Article II of this Agreement with respect to the Nielsen Intellectual Property, then Article III shall prevail. ARTICLE IV. FURTHER ASSURANCES AND COOPERATION. Section 4.01. Without limiting the obligations of any party under Article III of this Agreement, each Party hereto shall execute and deliver, or cause to be executed and delivered, as and when reasonably requested by any other Party hereto, all such documents and instruments and shall take, or cause to be taken, all such further or other actions as such other Party may reasonably deem necessary or desirable to effect the purposes of this Agreement and/or to clarify or confirm the respective ownership rights of the Parties as provided for in this Agreement. Section 4.02. Without limiting the obligations of any party under Article III of this Agreement, each Party hereto shall reasonably cooperate with the other Parties with respect to any government filings or any other actions reasonably necessary to maintain and enforce the rights to the Intellectual Property covered by this Agreement. Section 4.03. Without limiting the obligations of any Party under Article III of this Agreement, each Party hereto shall, upon the prior written request of another Party, arrange for the provision of appropriate copies of Records in its possession or control (or the originals thereof if the Party making the request has a reasonable need for such originals) created prior to the Distribution Date and relating to the Intellectual Property, as soon as reasonably practicable following the receipt of such request, but only to the extent 13 such items are not already in the possession or control of the requesting Party.

In the event of any inconsistency between this Agreement and the LLC Agreement, this Agreement shall prevail. Other than Sections 2.7, 2.14 and 4.5 of the Distribution Agreement, which shall prevail over any inconsistent or conflicting provisions in this Agreement notwithstanding any other provisions in this Agreement to the contrary, in the event and to the extent that there shall be an inconsistency between the provisions of this Agreement and the provisions of the Distribution Agreement, this Agreement shall prevail.
