     WHEREAS, Citadel concurrently herewith has made an equity investment in comScore; and

     WHEREAS, the terms of such equity investment have induced Citadel to enter into this Agreement, and the terms of this Agreement have induced Citadel to make such equity investment;

     NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Citadel and comScore agree as follows:

1.

DEFINITIONS

     The terms used in this Agreement with initial capital letters shall have the respective meanings set forth in the Agreement (including this Article 1).

1.1

comScore Materials. “comScore Materials” means all tangibles and intangibles owned, controlled or licensed by comScore or its Affiliates whether created pursuant to this Agreement or otherwise including, but not limited to, the Core Materials, Non-Core Materials, comScore Trademarks, comScore Developed Materials, Know-How, Intellectual Property and Documentation. For purposes of

this Agreement, Core Materials, Non-Core Materials, comScore Trademarks and comScore Developed Materials (including Know-How, Intellectual Property and Documentation related thereto) are collectively referred to herein as “Licensed Materials.”

Notwithstanding the foregoing, comScore and Citadel may disclose the existence and terms of this agreement and other necessary Confidential Information to its debt or equity sources of funding, attorneys and accountants, subject to a confidentiality agreement entered into between comScore or Citadel, as applicable, and such sources. Each party may, however, disclose the Confidential Information of the other to those of such party’s personnel, subcontractors, or agents engaged in a use permitted by this Agreement (excluding the comScore and Citadel Competitors) and with a need to know, provided that such personnel, subcontractors, or agents: (i) are directed to treat such Confidential Information confidentially and not to use it other than as permitted hereby and (ii) are subject to a legal duty to maintain the confidentiality thereof. Each party shall be responsible for any improper use or disclosure of any Confidential Information of the other by such party’s and its subcontractors’ officers, partners, principals, employees, agents or independent contractors (including individuals who hereafter become former partners, principals, employee, agents or independent contractors).

Required Disclosure. The Receiving Party shall not be liable to the Disclosing Party for disclosure of any of the Disclosing Party’s Confidential Information if such disclosure is made pursuant to a governmental or judicial mandate, provided that the Receiving Party shall have given the Disclosing Party immediate notice of such mandate prior to the submission of said Confidential Information and taken all reasonable steps and cooperated with the Disclosing Party to limit or restrict such disclosure and further provided that the Receiving Party shall have taken no action to prevent or interfere with any lawful efforts the Disclosing Party might take to intervene in any such proceedings or otherwise prevent such disclosure.

	9.4		Confidentiality Agreements. comScore covenants that each of its employees and the employees of any and all permitted subcontractors performing Services shall be subject to the terms of an employment or other agreement that (a) requires such employee to protect comScore’s clients’ confidential information, including Internal Citadel Data, and that offers no less degree of protection than that which is required hereunder and (b) in the case of employees, requires such employee to grant its employer ownership of, or in the case of permitted subcontractors, requires the grant of ownership to comScore of any and all comScore Materials and Citadel Owned Developed Materials created or developed by such employee. Without regard to whether any individual is subject to any such agreement and without regard to its terms, comScore shall be responsible for, and shall remain fully liable for, any action or inaction by each of its agents and permitted subcontractors, and each of their employees, with respect to the Confidential Information and Internal Citadel Data that results in a breach of this Section 9.

	9.6		Return of Confidential Information. Unless a party is expressly authorized by this Agreement to retain the other party’s Confidential Information, such party shall promptly return or destroy, at the disclosing party’s option, the disclosing party’s Confidential Information, and all copies thereof, within five (5) days of the disclosing party’s written request, and shall certify to the disclosing party that it no longer has in its possession or under its control any Confidential Information in any form whatsoever, or any copy thereof.

in the six-month period after the expiration of the Term, without the prior written consent of the other party, directly or indirectly:

	10.3.2.		in addition to its right to damages and any other rights the non-breaching party may have, injunctive or other equitable relief to restrain any breach or threatened breach or otherwise to specifically enforce the provisions of Section 10.1 and 10.2 of this Agreement, it being agreed that money damages alone would be inadequate to compensate the non-breaching party and would be an inadequate remedy for such breach.
	10.3.3.		The rights and remedies of the parties to this Agreement are cumulative and not alternative.

COMSCORE TECHNOLOGY

comScore
Population Size Estimation, Panelist Description,
In-Tab Sample Selection & Projection Weight Calculation

Models, algorithms and analytical tools related to the following:

1. Population Definitions

comScore currently provides measurements for these four populations:

U.S. Home. This is the population of computers used to access the Internet for more than e-mail in the last [* * * *] days from private residences in the U.S., excluding those that are in private residences for which a head of household is a fulltime student and those that are in a home office. A fulltime student is someone who was enrolled fulltime at a post-secondary, title IV institution in the most recent October. A home office is a place in a private residence from which a resident operates a business.

U.S. Work. This is the population of computers used to access the Internet for more than e-mail in the last [* * * *] days from workplaces in the U.S., except for those computers that have more than one user and those for which Internet access is significantly restricted. Workplaces include home offices, where a home office is a place in a private residence from which a resident operates a business. There are four categories of Internet access: unrestricted, screened, targeted, and e-mail only. A computer’s access to the Internet is significantly restricted if the access is only “targeted” access, which means that a user can view pages only from domains in some list of domains, like an intranet plus documented research sites, or if the computer can only send and receive email. A computer’s access to the Internet is not significantly restricted if the access is “screened,” which means that a user cannot view pages from domains in some list of domains, like known adult or gambling sites, or if the access is unrestricted.

U.S. School. This is the population of computers owned by full-time students that have been used to access the Internet for more than e-mail in the last [* * * *] days from group quarters or a private residence for which a head of household is a full-time student. A fulltime student is someone who was enrolled full-time at a post-secondary, title IV institution in the most recent October. Group quarters include dormitories and fraternity and sorority houses. This population excludes computers that are not privately owned, such as the computers owned by educational institutions.

International. This is the population of computers used to access the Internet for more than e-mail in the last [* * * *] days by people who are not residents of the U.S.

2. Population Size Estimation

U.S. Home. The size of the U.S. Home population in any month is estimated in these three steps:

	1.		We estimate the proportion of households that have at least one member accessing the Internet from a computer in the U.S. Home population. The data used to estimate this proportion are from a continuously administered telephone survey, that we call the Population Survey ([* * * *] completed interviews every month) of adults living in private residences in the U.S. The survey is administered by [* * * *] effective September 2003. Only one adult in any household is interviewed. For any month, the estimate of the proportion is the average calculated with the data collected during the 20 weeks ending with the week containing the last day of the month. This same survey also yields estimates of the average number of computers in the U.S. Home population calculated across households that have at least one.
	2.		We estimate the total number of households in any month by linearly interpolating between projections purchased from another company, [* * * *], that are based on both the decennial census and the Current Population Survey.
	3.		We multiply the estimated number of households by the estimate of the proportion of households with at least one member accessing the Internet from a computer in the U.S. Home population. This then is multiplied by the average number of computers in the U.S. Home population calculated across households with at least one.

U.S. Work. The size of the U.S. Work population is similarly estimated in three steps:

	1.		We estimate the proportion of adults who access the Internet from a computer in the U.S. Work population, and we calculate the average number of such computers across adults who use at least one. The same Population Survey that provides data for estimating the size of the U.S. Home population also yields the information required to estimate this proportion of adults. The proportion is an average calculated with the data from the 20 weeks ending with the week containing the last day of the month.
	2.		We use data acquired from [* * * *] and linear interpolation to estimate the number of adults in any month.
	3.		We multiply the estimated number of adults by the estimate of the proportion of adults accessing the Internet from a U.S. Work computer. This then is multiplied by the average number of U.S. Work computers calculated across adults who use at least one.

U.S. School. We use information from both primary research and secondary sources to estimate the total number of computers owned by students and used to access the Internet.

The U.S. School population consists of two segments: computers belonging to students living in group quarters (21%) and computers belonging to students living in a private residence headed by a full-time student (79%). To estimate the size of the first segment, we ask respondents [* * * *] survey how many of their family members are students living in group quarters and how many of them own a computer that they use to access the Internet. From this we derive the rate at which students living in group quarters own computers and use them to access the Internet. We then apply this rate to estimates of the total number of students living in group quarters obtained from [* * * *].

To estimate the size of the second segment, we use responses to the Population Survey from people in households headed by fulltime students. We estimate the proportion of households that are headed by fulltime students, the proportion of those for which at least one member uses the Internet, and the average number of computers used to access the Internet among those households with at least one such computer. We take the product of these and multiply it by our estimate of the number of households in the U.S.

We corroborate our estimates of U.S. School computers by looking for consistency with information from a periodic survey of college students called [* * * *], information published by institutions that require computer ownership, and other public or syndicated research of students.

International. We currently do both primary and secondary research to estimate the numbers of computers used to access the Internet in each of 240 countries. In Canada, we have commissioned [* * * *] to do a quarterly survey. We also purchase data from periodic surveys executed by other research companies, such as [* * * *], which enables population enumeration for about 40 countries. Finally, to estimate the sizes of populations in remaining countries, we use summarized data from a large number of reports from inter-governmental agencies, like the [* * * *] and the [* * * *]; from government statistical agencies, such as [* * * *], the [* * * *], and the [* * * *]; from private research organizations, such as the [* * * *]; from news releases; and from companies making mechanical measurements of the size of the Internet, such as [* * * *].

3. Panelist Description

Our projection process includes post-stratification and so requires descriptive information about the computers in our samples and the households that use them. Most of this information is obtained in the “registration process,” the online process required of someone who has been persuaded to include one’s computer in [* * * *]. However, sometimes a participant does not answer all questions, answers some questions falsely or, over time, a participant’s answers become outdated.

For U.S. panelists, we test for incorrect information. For all U.S. panelists, we purchase demographic data from [* * * *], and we also have block-varying projections of household characteristics based on Census data. We compare information provided during the registration process to the [* * * *] and Census data and search for inconsistencies that suggest that the data from the registration process are false. In cases where we do not have a response to a registration or we suspect the response we have is false or outdated, we will substitute information acquired from [* * * *] or inferred from the Census data. For the work sample, the [* * * *] data does not provide information about the company size in the place of work. This limits comScore’s ability to adjust for company size in its work projections.

For panelists outside of the U.S., we do not currently buy data from [* * * *] or any similar company.

For all panelists, including those not in the U.S., we automatically search the data we continuously accumulate for evidence of panelists’ ages and genders, and we record and use this information in cases where panelists did not provide the information during the registration process. We also use the data we continuously accumulate to detect a panelist’s current ISP, connection type (broadband or non-broadband), and use of languages (we count the numbers of pages requested that use each of the major languages).

4. In-Tab Sample Selection.

For any month, we select a subset (the “in-tab sample”) of the computers that have been registered for [* * * *] for the calculation of measurements for the month. The criteria for that a computer must satisfy to qualify for the in-tab sample for a month include:

	•		[* * * *]
	•		[* * * *]
	•		[* * * *]

•

[* * * *]

The in-tab sample selection process is the same for all populations.

5. Projection Weight Calculation

To calculate projection weights for computers in the U.S. Home population, we stratify them on characteristics of the computers and of the households that use them, including certain aggregate measures of Internet activity. These include:

[* * * *]

The underlying assumption, behind the projection weights, is that the sample (both machine and people) within each strata is representative of the population in the same strata. There maybe other strata that are appropriate and practical in the future, that take into account other demographic variables, Computer Characteristics such as the number of machines used in the household to explicitly adjust for multiple machines in the household that are not monitored by [* * * *], or other more detailed Internet Activity.

Our information about the distribution of these characteristics in the population has three sources. We estimate the joint frequencies of the demographic variables with data from the Population Survey. The marginal distributions of service provider, browser used and connection type are also estimated with data from the Population Survey.

Joint frequencies of the measures of Internet activities are projected from a calibration sample. A calibration sample is a relatively small probability sample of computers recruited so that it will not have the biases of a panel recruited using primarily online advertising and e-mail solicitations, which are the primary means of recruiting computers for the [* * * *] panel. Although much smaller than the in-tab sample, it is sufficiently large to estimate the frequency

distribution of Internet user sessions and the frequency of visits to any domain in a cluster of domains. The calibration sample consists of the computers used by [* * * *] households, the panel of households acquired when Media Metrix assets were purchased, which are households recruited from among those with telephone numbers in random samples. We continuously recruit households for the [* * * *] panel to replace those that leave the panel. Samples are purchased from [* * * *] and the recruitment is done by [* * * *].

To project population distributions from the calibration sample, projection weights are calculated for computers in this sample. This is done by stratifying them on region of residence, total income and total size of the households that own them. The number of U.S. Home computers in each stratum is estimated using the responses to the Population Survey obtained during the [* * * *] weeks ending with the week that includes the last day of the period for which weights are required. The weight for each computer in a stratum is this estimate divided by the number of calibration sample computers in the stratum.

▇▇▇▇▇▇▇, Categorical Data Analysis, 1990

To calculate projection weights for the sample of computers used to access the Internet by people not in the U.S., we stratify first on country group, and then have different methods for calculating weights for different country groups. Many country groups consist of a single country, such as Canada.

For Canada, we stratify on characteristics of the households using the Internet, on characteristics of their members, and on a measure of the intensity of use of “Canadian sites”.

The distribution of the population by frequency of use of Canadian sites is projected from a calibration sample, which is the subset of Canadian panelists who are [* * * *] panelists.

For the UK, France, and Germany, we stratify on:

[* * * *]

For 20 other countries, we stratify on:

We stratify on language use because large numbers of panelists from these countries registered at our English-language registration sites. The source of distributions of the populations of Internet users in other countries by language use is [* * * *] survey.

MEDIA METRIX 2.0 TECHNOLOGY

Media Metrix 2.0 presents marketers, ad agencies and content providers with the most comprehensive Internet audience measurement system in the industry. Media Metrix 2.0 was introduced in November ’02 and is the end result of the integration of:

Media Metrix				comScore Networks’
who created online media measurement				enhanced capabilities to capture online
and set the industry standard for Internet		+		transactions & niche audiences
reporting

The following discusses Media Metrix 2.0 study procedures, highlighting major changes and benefits incorporated from the legacy Media Metrix service. Please feel free to contact your account representative with any additional questions or comments.

SAMPLE AND FIELDWORK

Media Metrix 2.0 is based upon a core panel of Internet users that is recruited using Random Digit Dial (RDD) methodology, supplemented by sizable numbers of work and university panels recruited online. Integration of the latter two panelist groups provides increased granularity of reporting. As a result, Media Metrix 2.0 now provides increased data detail and reliability essential to making better informed decisions for online advertising, marketing, and commerce.

CORE PANEL SAMPLE AND RECRUITMENT

comScore Media Metrix uses Random Digit Dial (RDD) recruitment methodology to build the core U.S. panel that has served as the industry standard in Internet audience measurement. RDD procedures are essential to building representative panels that minimize bias in the initial contact and subsequent recruitment. The panel was comprised primarily of Internet users from home and work, with some limited representation among university students.

Recruitment starts with the acquisition of random-generated samples of telephone numbers from working exchanges and then matched to national directories to obtain mailable addresses where possible. Households with matching phone numbers and mailing addresses are mailed a recruitment package seeking their participation in the panel. This mailer is designed to encourage panel membership by more fully describing the benefits of panel membership. It allows for ▇▇▇▇▇▇ discussion of how panelist’s behavior is measured unobtrusively and provides potential panelists with the information and time to make an informed decision on whether to join the panel.

All non-responders to the mailing, as well as households with non-matching phone numbers, are called directly by telephone to enlist their participation in the panel. Up to [* * * *] recontacts via phone/mail are made to everyone in the sample to ensure as complete coverage of all potential panel members, as possible.

Persons agreeing to panel membership are re-screened to confirm eligibility (must use Internet). They join the panel by entering into a panel membership contract, including an expressed privacy agreement, and completing a short survey describing Internet users in the household. Note: other eligible household members (2+ years old) are enrolled at this time.

Persons who use the Internet at work are directed to set-up measurement of their online behavior at this location, if they are the primary user of their work PC. These persons comprise a very important sub-group within the core panel and comprise the base for at-work Internet reporting. Students (18+) living in dormitories or off-campus apartments are now included in the College/University sample rather than Home sample.

WORK AND UNIVERSITY SUPPLEMENT SAMPLES AND RECRUITMENT

The Media Metrix 2.0 panel also includes supplementary samples representing usage from the workplace and college/university environments. The addition of these panelists improves the robustness and reliability of information on Internet usage data from these locations that are increasingly critical to a ▇▇▇▇▇▇ understanding of the online marketplace.

Workplace Measurement: Historically Media Metrix reported at-work Internet usage from panelists recruited via RDD (as described above).

Despite a lengthy and intense effort over the last four years to increase the effectiveness of RDD in building a more robust workplace panel, the total at-work panelists never exceeded [* * * *] users. The at-work sample was adequate for reporting overall workplace Internet usage, but limited when providing detailed coverage of smaller sites, business-to-business vendors, and critical volume of online transactions during workday hours. It became clear that broader recruitment strategies would have to be implemented.

After extensive study, comScore Media Metrix adopted a hybrid recruiting methodology which maintains RDD recruitment while using online recruiting to supplement the at-work sample. The latter online procedure is akin to research procedures of over-sampling of hard to reach sub groups that are then weighted-back to proper representation.

That RDD procedures alone are insufficient for building meaningful work samples was buttressed by the ARF in a recent analysis of comScore recruitment methodology for the netScore product (the sister service to Media Metrix 2.0). The ARF noted that:

The industry’s veneration of probability samples stems from the conviction that we are less likely to have bias in our measurement with this sampling, and that if bias does somehow sneak in, with random sampling, we are equipped to find it and root it out. However, that conviction has weakened with the continuing declines in response rates to levels that, for some, has made “random” a dubious promise.¹

The ARF also found great benefit in the use of increased sample sizes “to take media measurement the “final mile” – from media exposure to advertising exposure and even to linking that exposure to behavioral response.”²

As already stated: The Media Metrix 2.0 work sample includes the sample of users recruited via traditional RDD and originally included within prior Media Metrix reporting supplemented by a diverse sample of employed Internet users recruited via online.

UNIVERSITY MEASUREMENT

Like the workplace sample described above, the Media Metrix 2.0 sample includes college/university students (18+) recruited via RDD supplemented by a diverse student sample recruited via electronic means. The RDD recruitment enlisted students in homes; the supplementary sampling also enlists students in dorms.

Historically, Media Metrix did not report university users separately, but they were counted as part of the home sample. The RDD and supplementary university sample was implemented in response to marketer’s desire for in-depth coverage.

This change not only provides the ability to analyze Internet usage of full-time students, but also provides a sharper picture of at-home only usage, without potentially confounding activity from college users who may reflect usage different from that of the typical home use

PANEL MEMBERSHIP

Panelists receive incentives ranging from [* * * *] quarterly to protection from viruses for their e-mail.

INTERNET UNIVERSE ESTIMATES

The release of Media Metrix 2.0 signaled two immediate changes in the universe estimates. The first is the projection of home, work, college, and total (home + work + college), that is consistent with the audience segments reportable in the service.

The second change involves the universe estimates for the total online-population, which shows an increase from prior Media Metrix reports because of a correction in the projection process made to address a slight understatement in legacy Media Metrix universe estimates. Note: This correction was being phased-in over time but the release of the 2.0 platform provided the opportunity for a quick fix. The methodology for projecting the US Internet universe has been maintained from legacy Media Metrix.

Media Metrix has contracted ▇▇▇▇▇▇▇▇ International to conduct an ongoing survey of US households to enumerate who is using the World Wide Web. The surveys use probability sampling and random-digit dialing methodology. Each month, up to [* * * *] minutes telephone interviews are completed with one person per household.

The information gathered by the enumeration surveys is used to derive estimates of the proportion of the US population that currently uses the Internet. The enumeration survey provides the estimated proportion for:

	•		Persons 2+, using the Internet at home
	•		Adults 18+, using the Internet at home/work

A [* * * *] week rolling average is used to ensure stability in proportion-estimates derived from these surveys. The derived-proportions are then applied to [* * * *] to calculate target population sizes.

Enumeration of students accessing the Web is similar to the above. The school population is segmented into two groups of students, those living in group quarters and those in a private residence headed by a full time student. The population Survey provides the basic information used to derive at-college Internet population proportion, which is then applied to estimates of the total number of students obtained from [* * * *] to derive targets.

The enumeration is also used for determining variable-targets for sample balancing purposes. The variable-targets used include: gender, age, household income, # of people in households, presence of children and region. Iterative proportional fitting is used to the weight panelist sample to correct for panel imbalances and thereby enhance its representation of the Internet population.

The enumeration procedure outlined above is used to establish universe estimates for Total Digital Media. Internet activity currently reported for the US populations are shown in the table below:

Digital Media & World Wide Web Universes (October 2002)

		Digital Media
		(Millions)
Total population:
Persons 2+, used the Internet			142.7
Persons 2+, used the Internet at Home			123.8
Adults 18+, used Internet at Work			47.9
Adults used Internet at both Home/College and Work			38.5
Adults 18+, used Internet at University			9.5

AUDIENCE ESTIMATES

Enhancements to Media Metrix 2.0 also provided the opportunity to re-examine the legacy-weighting scheme with regards to audience estimates, which led to a new weighting scheme for projecting unduplicated audiences. The new scheme better estimates Internet usage between dual usage locations.

Legacy audience projection: The integration of home and work panel data used in audience projections required identification of panelists who accessed the Internet at both locations. Simply adding panelists who visited a site from either location would double-count those who visited the same site from both sites. As a result, estimates of unduplicated site audience required a correction procedure that subtracted the total number of dual-location site-visitors from the sum of total visitors from home and total visitors from work. This procedure generally produced satisfactory, unbiased unduplicated audience projections.

However, since the combined home/work panel group is a sub-set of total home users and total work users, the correction procedure could provide volatile projections for sites with small audiences. The projected unique visits by people visiting the Internet from both home and work had the possibility of being larger than either the projections of the at home or at work estimates so that the resulting unduplicated audience could be smaller than the audience from one or both of the home/work panels. This problem arose because of the large variance of estimates obtained as based on small size of this sample.

Media Metrix 2.0 audience projection: Media Metrix had been considering the implementation of a new method for estimating total site audience based solely on visiting either from home or from work. The method is based on defining a function that includes a parameter whose value can be estimated from a “both” sample. This parameter represents the correlation of a visit to a web entity from home with a visit to the same entity from work among people using the Internet from both locations. For the current report, the parameter values were calculated by averaging across six months. The details of how the modeling is derived and how it is applied in audience projection are available upon request.

DATA COLLECTION TECHNOLOGY

Media Metrix 2.0 features comScore’s proprietary, patent-pending proxy measurement platform. This

advanced monitoring technology operates on a high-performance server network that captures usage data as it flows between each panelist’s PC and the Internet. This represents a major improvement from the older approach of collecting data through a software “meter” installed on each user’s PC. The comScore measurement platform provides uninterrupted reporting of all previously measured Internet behavior including expanded coverage of AOL and other proprietary networks. This platform also captures the details of crucial activities such as online buying, subscriptions, search engine queries, etc.

OVERVIEW OF PROXY METHODOLOGY

Upon agreement to join the comScore panel, members’ browsers are configured to unobtrusively route their Internet activity through comScore’s network of dedicated servers. At the start of Internet activity, panelists identify themselves from a list on the User Identification Screen (allowing for measurement of user age, gender, education and other demographics). The identification screen disappears and computer usage continues as normal. If the computer is inactive for more than 30 minutes during an online session, the user is again prompted for identification, to ensure that any change in user is properly reflected.

The panelist’s Internet activity is captured regardless of type of browser used. This is important since many users use multiple browser brands and versions – sometimes simultaneously – when surfing the Web. Activity is captured regardless of whether an Internet connection is established via a commercial Internet Service Provider (ISP) or an office-hosted LAN. Information that can potentially be captured on an individual member basis includes site visited, page viewed, ad seen, promotion viewed, product or service bought, price paid, and more. This contrasts to the data collection system employed prior to Media Metrix 2.0, which was limited to capturing activity via the URL window in a panelist’s browser. Data capture and reporting are conducted in adherence to strict, industry-leading privacy protection policies. Data provided by participating panel households about each Internet user’s identity are stored in an encrypted, access-controlled database. Data is reported only in aggregate form.

BASIC URL CAPTURE

Media Metrix 2.0 data are collected via a proxy server methodology which is very similar to that used to track server logs. The proxy captures the details of communications to and from a panelists’ computer on a site-specific, individual-specific basis. This capture ranges from outgoing browser commands to view a page (i.e. internet content) to incoming fulfillment including pages, ad banners, pop-ups etc. Currently, requests for image files (this would include most banner ads) are not routed through proxy servers but to servers serving these files.

The proxy captures the full URL address of each individual item that comprises a page (request fulfillment) such as banner, heading, etc. These are matched to a dictionary of URL addresses currently numbering over [* * * *] Internet sites. Capture of browser requests are important to in determining whether the Internet session is live or whether the in the background. Note: because the to and from communications are captured and stored on the proxy servers, actual pages can be called up for further coding and identification purposes.

DIGITAL APPLICATIONS MEASUREMENT

In addition to improving the capture of basic website visitation, the change to the proxy collection method has allowed for enhanced measurement of a number of digital media applications. The two most immediate affected applications are described below.

1.		AOL PROPRIETARY: One of the most significant enhancements of the new proxy data collection system is an improved measurement of the AOL Proprietary network. In Media Metrix’ legacy processes, measurement of AOL relied on collection of the titles in users’ Blue Bars (the text that appears in the upper left hand corner of pages within the proprietary service).
		While this method was largely reliable for cataloging AOL proprietary pages, it required significant manual effort to link non-standard Blue Bar titles to respective channels within AOL. This effort was further complicated whenever the coding team encountered ambiguous Blue Bar titles that were not immediately identifiable with a particular channel. These were ultimately coded using a series of rules based on assumptions to approximate proper channel classification.
		The newly implemented system captures the unique proprietary URL that is associated with each page of the AOL service, thereby allowing to track and report the AOL Proprietary service in the same automated manner as standard websites. Each proprietary URL contains a code that is unique to a channel and these unique codes have been identified and attributed to the proper AOL Channel.
2.		INSTANT MESSENGER SERVICES: The legacy meter was only able to see that a messenger application was active but could not determine any level of user interaction with the tool. The proxy technology observes instant message packets transmitted to and from panelists machines and can detect the difference between when a user sends an instant message, and when information is forced to the user’s messenger application, (i.e. when a stock quote is automatically updated in an instant messenger application.) Records of when users actually send instant messages are now used to calculate measures of Unique Visitors.

SCHEDULE 7.1.1

METHODOLOGY

Panel Recruitment and Composition

Inclusive of all samples under measurement, comScore Networks collects data from a total panel of approximately 1.5 million global Internet users.

comScore Networks uses an industry-standard Random Digit Dial (RDD) telephone and Random Direct Mail (RDM) methodology to recruit a core U.S. panel of up to [* * * *] Internet users.

Recruited participants join the comScore panel by entering into a panel membership contract that gives comScore explicit permission to monitor all online activity that occurs on their computers. Each panelist provides their name and household address, and completes a short survey identifying all Internet users in the household and key demographic characteristics in the household. Panelists also agree to receive periodic online consumer surveys from comScore.

comScore enhances this core panel with the addition of three unique samples:

	•		[* * * *]-person U.S. at-work panel
	•		[* * * *]-person university panel
	•		[* * * *]-person “megapanel” – allowing analysis at the worldwide level, across dozens of countries and regions, and nearly [* * * *] local markets across the U.S.

These three groups have been recruited using opt-in online techniques.

Population Estimates

comScore conducts regular surveys, again using an RDD methodology, to enumerate the size and characteristics (e.g., demographics, type of Internet connection, etc.) of the Internet-using population. These universe estimates are updated on a monthly basis to account for the growth of Web users. Using a sophisticated and proprietary systems, all comScore sample data are stratified and then balanced and weighted according to the enumeration data to ensure accurate representation of the online population. Projection weights are developed through iterative proportional fitting and the target population percentages are derived from the monthly enumeration data.

comScore Data Collection Technology

Upon agreeing to join the comScore panel, participants’ browsers are configured to unobtrusively route all of their computers’ Internet activity through comScore’s network of several hundred dedicated servers. This technology captures the details of all online sessions, including all communication to and from each individual’s computer, on a site-specific, individual-specific basis.

comScore’s systems capture the majority of http and https requests of consumer interest, across publicly accessible Internet sites, and the majority of Internet ▇▇▇▇▇▇▇ used. This is relevant since some people use multiple browsers – sometimes simultaneously – when surfing the Web. Activity is also captured regardless of whether an Internet connection is established via a commercial Internet Service Provider (ISP) or an office-hosted LAN.

comScore’s technology operates throughout non-secure and secure (SSL) connections, and across HTML and proprietary (e.g., AOL) content. The information comScore routinely captures goes far beyond the limitation of traditional clickstream data, by encompassing data on every site visited, page viewed, ad seen, promotion used, product or service bought, price paid, and more. comScore also collects merchant-specific information contained in the credit card statements that are viewed online by panelists, allowing for the estimation of both online and offline spending. comScore’s data capturing and coding technology can also be customized to identify and capture virtually any event or sequence of events or content deemed to be critical to a client analysis.

SCHEDULE 7.1.2

CERTAIN STANDARDS

1.		comScore will conduct monthly Mystery Shops on randomly selected sites with an emphasis on the top [* * * *] visited sites.

The average number of improperly captured pages in a transaction during the monthly Mystery Shops shall not exceed [* * * *]%. “Mystery Shops” is defined as having properly instrumented machines conduct actual ecommerce and travel transactions at sites/domains coded by comScore and comparing the transaction detail as it happened on the machine to the transaction detail as it was captured and recorded by the comScore Data collection system.
2.		comScore will maintain a comScore Data collection system record loss of less than [* * * *] percent [* * * *]% per month.
3.		comScore’s data collection network for its collection of comScore Data shall be operating and available at least 99% of the time in any given month.
4.		comScore shall operate its comScore’s data collection network across a minimum of [* * * *] separate Internet backbones.
5.		Each data center will have at least [* * * *] autonomous uplinks.

Such hours shall expire in April 2007 and shall not be included in any calculation of the carry-forward of Services Commitment hours as specified in Section 3.4. Unless specified by Citadel in writing, Services performed under the Agreement shall first be applied to the existing balance of Services Commitment hours and then to the balance of Supplemental Services Commitment hours. The hours available under the Supplemental Services Commitment may be used by Citadel in the same manner as the hours available under the Services Commitment.
3.		comScore Personnel – Key Personnel. The parties shall designate at least one (1) comScore employee (the “Key Personnel”) to perform Services for Citadel at Citadel’s offices, Monday through Friday, eight (8) hours per day, subject to Citadel’s holiday schedule, unforeseen personal events requiring that such Key Personnel take leave (e.g., illness, jury duty, etc.), Key Personnel’s personal vacations, Key Personnel’s attendance at periodic employee and team meetings reasonably required by comScore (e.g., seminar on benefits, meeting on state of the company, etc.) and Key Personnel’s attendance at comScore-sponsored training or professional development opportunities as reasonably required by comScore. Prior to his/her assignment as Key Personnel, the comScore employee selected for such assignment must agree to accept such assignment for a twelve (12) month period without the ability to request a transfer within comScore. Commencing on April 20, 2004, the initial Key Personnel is [* * * *], who has agreed to accept his assignment through April 20, 2005. The first date on which a comScore employee serves as Key Personnel shall be referred to as the “Key Personnel Start Date.” The last date on which a comScore employee serves as Key Personnel shall be referred to as the “Key Personnel End Date.” The twelve-month period during which the Key Personnel serves as Key Personnel shall be referred to as the “Key Personnel Term”. Except as set forth herein, during the Term, comScore shall not: (i) replace or reassign the Key Personnel, except if such Key Personnel is incapacitated or resigns; or (ii) terminate the employment of any of comScore’s Key Personnel, except with regard to termination for “good cause” (which term, as used in this Agreement, shall mean cause for termination as determined in accordance with comScore’s employment policies, consistently applied). No less than ninety (90) days prior to the then-current Key Personnel End Date, comScore shall notify Citadel either (a) of its intent to extend the then-current Key Personnel Term by an additional twelve (12) month period commencing on the anniversary of the then-current Key Personnel Start Date, or (b) replace the existing Key Personnel with a new Key Personnel, such replacement to be effective on a date specified by comScore, which date shall be no less than ninety (90) days after Citadel’s receipt of such notice (except to the extent that such period is made impossible, due to unforeseeable circumstances beyond Vendor’s reasonable control). Thirty (30) days following such notice (except to the extent that such period is made impossible, due to unforeseeable circumstances beyond Vendor’s reasonable control), comScore shall designate the replacement Key Personnel that is at least as well qualified to perform such functions and responsibilities as the person being replaced, such replacement to be subject to the consent of Citadel, such consent not to be unreasonably withheld. In making any such replacement, comScore shall ensure that there is at least a sixty (60) day period of overlap during which the person being replaced transfers appropriate knowledge and provides appropriate training to the new holder of the position (except to the extent that such period is made impossible, due to unforeseeable circumstances beyond Vendor’s reasonable control). For each new Key Personnel and to cover the overlap period, Citadel shall receive two hundred (200) hours of Services from such new Key Personnel at no additional cost to mitigate the costs of transitioning to such new Key Personnel.
