Google Inc. AdWords Reseller Addendum

This Google Inc. AdWords Reseller Addendum (“Addendum”), effective as of May 1, 2011 (“Effective Date”), is entered into by the reseller executing this Addendum (“Reseller” or “Customer”) and Google Inc. (“Google”). This Addendum is an addendum to the Google Inc. Advertising Program Terms (available at www.google.com/ads/terms, the “Ads Terms”), which are hereby incorporated by reference. Any use of the AdWords API by Reseller will also be subject to the terms and conditions of the AdWords API (available at www.google.com/apis/adwords/terms.html, the “API Terms”). This Addendum, the Ads Terms, and, if applicable, the API Terms (collectively, the “Reseller Agreements”) govern Reseller’s participation in Google’s AdWords advertising program (the “AdWords Program”) as a reseller appointed by Google (the “Reseller Appointment”). Any capitalized terms not defined in this Addendum have the meanings assigned to them in the Ads Terms.

1. Reseller Appointment. Google authorizes Reseller to be a non-exclusive authorized reseller of AdWords Program advertising inventory that is made generally commercially available by Google (“AdWords Inventory”). AdWords Inventory can be sold by Reseller only to local small-medium advertisers, whose principal place of business is located in the United States, Canada, [*****] and [*****] (each an “Advertiser”). Based on market conditions and upon mutual agreement of the parties, parties may change the countries in which Reseller is permitted to sell AdWords Inventory under this Addendum. The Minimum Qualified Advertiser Threshold for North America is set forth in Exhibit B. 90 days prior to July 2012, parties will agree upon the Minimum Qualified Advertiser Threshold for [*****] and amend this Addendum to include the Minimum Qualified Advertiser Threshold for [*****]. 90 days prior to January 2014, parties will agree upon the Minimum Qualified Advertiser Threshold for [*****] and amend this Addendum to include the Minimum Qualified Advertiser Threshold for [*****]. Two Performance Periods after Reseller begins to sell AdWords Inventory in a particular country, parties may, upon mutual agreement of the parties, revise the Minimum Qualified Advertiser Threshold for that country. Parties acknowledge and agree that this Addendum is part of a global arrangement between Google and Reseller to extend the Reseller Appointment to various agreed upon countries. In the event this Addendum is terminated, parties will work together to re-evaluate the terms of the agreement in other regions to make sure that the mutual global goals of the parties are still aligned. Google, in its sole discretion, reserves the right to disallow certain Advertisers from being activated or served through Reseller (even after initially accepting the Advertiser). For purposes of clarification, AdWords Inventory does not include Google TV Ads; provided, however, that the exclusion of Google TV Ads inventory from this Addendum is not intended to limit any Google TV Ads inventory options available to Reseller without a performance bonus under the Ads Terms.

2. Obligations.

a. Reseller Obligations. Reseller will (i) use commercially reasonable efforts to activate Advertisers, (ii) ensure that any description of a final product incorporating AdWords Inventory that Reseller sells to Advertisers (“Retail Product”) includes the product characteristics set forth in Exhibit A, (iii) perform its obligation under this Addendum in a timely and professional manner with competent qualified individuals exercising due skill and care; (iv) make commercially reasonable and good faith efforts to comply with Google’s business partner due diligence process, including, without limitation, providing requested information; and (v) comply with all applicable laws, including, without limitation, the U.S. Foreign Corrupt Practices Act of 1977, which prohibit corrupt offers of anything of value, either directly or indirectly, to a government official to obtain or keep business. “Government officials” include any government employee; candidate for public office; and employee of government-owned or government-controlled companies, public international organizations, and political parties.

b. Google Obligations. Google will make available a dedicated Google AdWords account manager to support Reseller. Google will pay Reseller one performance bonus per Performance Period in accordance with Exhibit B provided that Reseller has complied with the conditions set forth in Exhibit B. Google may select the form of performance bonus (i.e., by check, wire transfer or AdWords Program credit) at its sole discretion.

c. Joint Obligations. Reseller and Google will have executive business reviews to discuss key operational, sales and marketing objectives, agreed upon actions and observed impact, and potential growth opportunities, the details of such business reviews (e.g., location, timing and format) to be agreed upon by the parties.

3. Brand Features. Each party will own all right, title and interest to trade names, trademarks, service marks, logos and domain names secured by such party from time to time (“Brand Features”). In performing its obligations under this Addendum, Reseller may only refer to itself as a “Google AdWords Authorized Reseller”. Google authorizes Reseller to display the “Google AdWords Authorized Reseller” Brand Feature, as provided to Reseller by Google in writing, in the United States, Canada, [*****] and [*****] during the Term solely in accordance with the Trademark Guidelines available at www.google.com/permissions/guidelines.html and solely for the purpose of fulfilling Reseller’s obligations set forth in this Addendum. Reseller must submit all materials containing Google’s Brand Features to Google for prior written approval. Reseller authorizes Google to use Reseller’s Brand Features in connection with this Addendum during the Term in connection with Google’s marketing presentations and materials (e.g., a web page created by Google that contains the Reseller’s Brand Features and links to the Reseller home page or relevant page on the Reseller’s website).

Reseller remains responsible for compliance of subcontractor and its personnel in all respects with this Addendum. To the extent that any act or omission by any subcontractor appointed pursuant to this Section 6 would constitute a breach of this Addendum if committed by Reseller, Reseller shall be liable to Google for such act or omission as if the act or omission had been committed by Reseller.

On a quarterly basis, Reseller will provide to Google a list of top Channel Partners and Google may work directly with such Channel Partners upon 6 month prior notice to Reseller.

12. Term; Termination. This Addendum will commence on the Effective Date and will continue through the third year anniversary of the Effective Date (the “Term”), unless terminated earlier in accordance with this Section. Either party may terminate this Addendum: (a) if the other party materially breaches any term or condition of this Addendum and fails to cure such breach within 30 calendar days after receiving written notice thereof; or (b) for any reason or no reason (1) before any renewal, upon 60 calendar days’ prior written notice to the other party and (2) after any renewal, upon written notice to the other party.

Notwithstanding the foregoing, with respect to subparagraphs (D), (E), (F) and (G), Google may only terminate with respect to the Reseller territory that has failed to comply with such requirements. Upon termination or expiration of the Ads Terms or the API Terms, this Addendum will automatically terminate. Sections 9(c), 11 and 12 will survive any expiration or termination of this Addendum. Termination or expiration of this Addendum does not (x) terminate the Ads Terms which will continue to apply to all AdWords accounts created by Reseller on its own behalf or on behalf of Advertisers, or (y) prevent Reseller from participating in the AdWords program pursuant to the Ads Terms.
