RECITALS

The parties wish to provide for a license to Partner to display LookSmarts Paid Listings on the Partner Network sent by LookSmart
in response to search queries, ad requests based on site pages, and other ad calls or requests for listings made by Partner to LookSmart.

NOW, therefore, for good and adequate consideration, the receipt of which is acknowledged, the parties agree as follows:



|1. | DEFINITIONS.

1.1 AClick occurs when a bona fide Internet user (which excludes a robot, spider, software, scraper or other mechanical, artificial or fraudulent means, or a person who is not seeking to use the Partner Network for a legitimate web
search, e.g., has been paid or otherwise motivated to click, as determined by LookSmarts click filtering and tracking systems) clicks on a Listing and accesses the destination site.

1.2 Listing means a link to a website that includes the display URL, a title, text that describes the site to which
the listing links or encourages the user to visit the site, and may include a tracking URL.

---

|3. | PAYMENT TERMS.
|-- | --------------

3.1
Cost Per Click. Subject to the terms and conditions hereof, for any given calendar month, LookSmart will pay Partner a share of revenues from LookSmart invoices or charges for all qualified Clicks on listings advertisements, as recorded by
LookSmarts, or its customers as applicable, click tracking systems. For each Click, the share of revenue paid to Partner will be equal to the cost-per-click (CPC) bid by LookSmart for the corresponding keyword(s), less a
month-end adjustment for credit card fraud, advertising complaints and similar items. LookSmart will determine the CPC bid and include it in the Paid Listings feed sent in response to such request. LookSmart will have sole discretion to decide the
CPC bid for each Listing, and such CPC bid may change frequently. Partner may use the CPC bid included in the Paid Listings feed from LookSmart solely for the purpose of ranking the Paid Listings and gauging payments from LookSmart, but the parties
agree that all CPC bid amounts submitted by LookSmart are confidential information for internal use only, and shall not be posted on Partners web pages or disclosed to any third parties. LookSmart shall have no obligation to pay for clicks if
Partner makes any material misrepresentations in Exhibit C or if Partner violates the license terms set forth in Section 2 above.

3.2 Reporting and Payment. LookSmart will make its PUBLISHER CENTER available to Partner for preliminary daily
reporting of clicks, and Partner acknowledges and agrees that (i) such reporting may not represent the number of qualified Clicks for which LookSmart will pay Partner and (ii) it will control access to and maintain the confidentiality of
its password for accessing the POP Portal. Within 30 days after the end of each calendar month during the Term, LookSmart will deliver (a) a report describing invoices and billings to LookSmart customers for such calendar month pursuant to
Section 3.1 and (b) payment pursuant to Section 3.1; provided, that Partner acknowledges and agrees that to the extent Partner has not provided the Query Source Identification as described in section 2.5, above. For every request,
without such information LookSmarts ability to determine which clicks and ads are qualified or billable is impaired and thus LookSmart may not pay Partner for the clicks and ads. Partner shall also notify LookSmart of any changes,
inaccuracies, or incompleteness of any statement Partner makes on Exhibit C, Part II. LookSmart reserves the right to deduct from payments made pursuant to Section 3.1, or otherwise recoup any amounts paid to Partner in prior months for
non-qualified Clicks.

3.3 Audit. Each party will maintain accurate records with respect to the calculation of all
Clicks and/or payments due under this Agreement. The other party (the Examining Party) may, upon no less than 15 days prior written notice to the first party (the Audited Party) and no more than once in any
twelve month period, cause an independent auditor of nationally recognized standing to inspect the appropriate records of the audited party reasonably related to the calculation of such Clicks and/or payments during the Audited Partys normal
business hours. Such examination will be undertaken in a manner reasonably calculated not to interfere with the Audited Partys normal business operations. The fees charged by such auditor in connection with the inspection will be paid by the
Examining Party, unless the auditor discovers an underpayment of greater than 10%, in which case the Audited Party will pay the reasonable fees of the auditor.

3.4 Non-qualified Clicks.LookSmart shall have no obligation to pay for clicks which are non-qualified clicks as determined
by its click filtering and tracking systems. Non-qualified clicks may come as a result of but are not limited to clicks (i) generated via automated crawlers, robots or click generating scripts, (ii) that an advertiser receives and rejects,
(iii) that come as a result of auto-spawning of browsers, automated redirects, and clicks that are required for users to navigate on the Partner Network, (iv) that are from users in countries other than those explicitly agreed to in
Exhibit C by Partner





---

and LookSmart, (v) that are on expired, cached or over-budget ads, or (vi) that come as a result of any incentive such as cash, credits or loyalty points. LookSmart reserves the right
to require Partner to provide server log files that include, but are not limited to, the daily number of clicks delivered to LookSmart. In the event that LookSmart determines in its sole discretion that Partner or any third party site in the Partner
Network has delivered non-qualified clicks, low quality traffic, or traffic that violates any material term of this Agreement, LookSmart may, at its option, (1) immediately terminate this Agreement upon written notice to Partner, or
(2) require Partner to immediately cease displaying, and allowing third party sites in the Partner Network to display, Paid Listings via any particular means, method, product, or third party distributor, and/or (3) not pay Partner for the
offending clicks.

3.5 Account Manager. LookSmart will provide a designated account manager to Partner.

EXHIBIT A

IMPLEMENTATION

The following Sections 1-7 apply to the distribution of Paid Listings on the Partner Network.



|1. | Display of Paid Listings. Partner will make or refer search queries, ad requests based on site pages, and other ad calls or requests for listings to
LookSmarts servers via a live data feed. If any Paid Listings are returned by LookSmarts servers in response to such requests, such Paid Listings will be displayed on the Partner Network. Partner will not display or allow any third party
in the Partner Network to display any CPC or price-related data that would allow users to determine the price paid by advertisers in connection with Paid Listings. Partner will cooperate with LookSmart to allow LookSmart to track Clicks on Paid
Listings displayed on the Partner Networks, including the use of redirects, tracking URLs or other methods as reasonably requested by LookSmart. Other than as set forth herein, Partner shall be solely and exclusively responsible for the design,
development, operation and maintenance of the Partner Network and for all advertising, sponsorship or other use of the media contained therein. Partner will implement the Paid Listings within ten (10) days of the Effective Date, such
implementation to be verified by LookSmart recording at least one Click attributable to the Partner Network.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Partner Display Ordering; De-duplicating. Partner represents that it sorts, ranks and delivers Paid Listings for the Partner Network as indicated to LookSmart in
Exhibit C, Part II. In the event that Partner decides to change the method by which it determines the ranking of its Paid Listings, Partner will provide to LookSmart thirty (30) days prior written notice of such change. Partner further
represents that, to the extent it displays its own or other third party listings on the Partner Network in addition to the Paid Listings, if any such listing is duplicative with any Paid Listing, Partner will decide whether to show such listing or
the Paid Listing on the basis of which one carries the higher CPC.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Position in Paid Listings. If Partner sorts, ranks and delivers listings on the Partner Network based on CPC amounts, a) Partner must deliver LookSmarts
Paid Listings above or in a more favorable position than (i) any other listing with the same CPC and (ii) the listing with the next lowest CPC; and b) Partner will in no way manipulate the Paid Listings to deliver LookSmarts Paid
Listings in a position below or less favorable than listings with CPCs lower than the Paid Listings.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4. | Top Bid Pricing. Partner agrees to provide LookSmart with an automated, regularly updated mechanism from which LookSmart can determine the bid prices (CPC
paid to partner) of the top 5 listings advertisements sent to Partner Network for individual and specific queries from Partner. For example, Partner may make available an API or other data interface that provides such data.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | CPC Bid.To optimize CPC bid pricing, LookSmart may designate Partner ad calls/requests to be directed to certain of its servers, and Partner shall follow such
designations as they are provided to Partner.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|6. | Traffic Volume and Increases. Partner will provide LookSmart with 3 days prior written notice before launching with new affiliates or traffic sources that
will, in Partners reasonable opinion, increase the number of Partner queries by the lesser of 50% over then-current levels or 500,000 queries per day. LookSmart will have no obligation to pay for Clicks for which a timely notice is not
provided under this section.
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|7. | Blocking Distribution. LookSmart may request that Partner block distribution of Paid Listings to a specified list of sources (keywords, portions of Partner
Network, sites and/or IP addresses) or via any distribution method deemed questionable by LookSmart. LookSmart also reserves the right to make a written request to Partner for it to block specific Paid Listings for display to specific domains. Once
LookSmart makes this request, LookSmart is not obligated to pay Partner for any clicks from such domain(s). If Partner identifies the domain that the query originates from to LookSmart, then LookSmart may perform this blocking. LookSmart reserves
the right to ask Partner to block any international traffic, including international queries and clicks, for international users and listings appearing on international sites. LookSmart also reserves the right to ask Partner to block all
adult-related traffic, including adult queries and clicks generated as a result of these adult queries. LookSmart may update the list of prohibited distribution partners or sources from time to time, in its sole discretion. All sources
contained within the list must be blocked from distribution by Partner as soon as practicable after, but in any event within 5 business days from, receipt of notice from LookSmart. LookSmart shall have no obligation to pay Partner for qualified
Clicks on Paid Listings after LookSmart makes the relevant request.

EXHIBIT B

Service Levels

Below is the level of service to be supplied by LookSmart in connection with LookSmarts provision of Paid Listings (the
Service). The Service to be provided to Partner shall consist of a feed of Paid Listings as defined in the Agreement.

Partner Implementation Guide. Following the execution of this Agreement, LookSmart will provide Partner with a partner
implementation guide to assist in the process of implementing the technical aspects of the Service. The parties will use commercially reasonable efforts to abide by the procedures and steps set forth in the guide.

Service Integration Technical Assistance. During the Term, LookSmart agrees to provide a designated technical account manager
during normal business hours (8am  5pm Pacific Time) to Partner to assist in the effective integration of the Service onto the Partners site. In no event will such support exceed ten (10) hours per month, and all such support will
be provided during business hours. The parties agree that the Service is provided in a standard format and is well documented. LookSmart will not provide technical assistance relating to on-site server configuration or programming.

Service Response Time. The load time for a non-page-load query (i.e. where the data returned does not include the formatted
page), as measured round-trip from the time Partner servers send a search request to LookSmart to the time of Partners servers receipt of a completed set of search result(s) will be less than 375 milliseconds at least 98% of the time, as
measured daily, weekly, and monthly, from domestic locations.

Service Uptime. The Service will be available 24
hours/day, 7 days/week. Scheduled downtime will be communicated to partners with 5 business days notice. The Service is guaranteed to be up 99.5% of the time as measured weekly and 99.8% of the time as measured monthly, excluding scheduled downtime.
Should LookSmart determine that a reconfiguration of the Service is required, such as major software version changes, changes in hosting facilities or other network reconfiguration; LookSmart will provide Partner with 30-day notice of such change,
and will work in good faith to minimize any Service outages.

Quality Criteria. LookSmart will use commercially
reasonable efforts to ensure that the Paid Listings returned by the Service shall not contain more than 3% Inactive Links out of any random sample of 10,000+ queries. Inactive Links shall be defined as any link provide by the Service
which, when clicked, does not result in the user receiving a web page within 60 seconds at least 3 out of 5 times in any 1 week period.

TECHNICAL SUPPORT

To ensure that problems with the Service are identified, addressed and resolved in a timely manner, the following framework shall be
followed for reporting problems, communicating progress on troubleshooting activities, resolving problems, and, if necessary, escalating the level of attention placed on such problems.This framework proposes a three-category approach to
technical support for dealing with problems. The first type deals with general technical support such as consultation regarding technical specification interpretation and understanding the process, the second with changes in the
Service, and the third addresses problem reporting and resolution associated with the Service.



---

Type 1: General Technical Support

This category of service provides consultation regarding the proper interpretation of format specifications and data, as well as support on how the
Service works, the quality or content of Service results for specific queries or how Partners might integrate the Service into their Web site(s). It does not address any desired changes in the basic service parameters. Within 3 business days of the
Execution Date of this Agreement, Partner will be provided with the names of both a business development account manager and a technical account manager who will provide this type of service during normal business hours, up to 10 hours per month,
for the first three months. Partner should expect a response to Type 1 issues within 2 business days, after which they should be escalated as detailed below.

Type 2: Changes

Requests for changes in
the Service should be directed to the business development account manager who will be assigned to Partner within 3 days of the Execution Date of this Agreement. Partner should expect a response to Type 2 issues within 2 business days, after which
they should be escalated as detailed below.

Type 3: Problem Reporting and Resolution

Problems reaching LookSmart servers (e.g., major networking issues, Service outage, etc.) should be addressed with the LookSmart Technical
Operations team as detailed below. ALL OTHER requests (e.g. product issues) should be treated as Type 1 or Type 2 issues.
