Developer Addendum

This Developer Addendum (this "Addendum") is effective as of May 14, 2010 (the "Effective Date") and is made between Facebook, Inc. ("we" or "us") and Zynga Game Network Inc. ("you" or "your"). We and you are sometimes referred to in this Addendum individually as a "party" and collectively as the "parties". The parties hereby agree as follows:

Recitals

We and you are parties to our then-current standard online Statement of Rights and Responsibilities (together with all referenced policies, terms and guidelines, including without limitation, the online Developer Principles and Policies and the Facebook Credits Terms, the "SRR") which set forth the terms and conditions for your use of Facebook. The SRR is located at http://www.facebook.com/terms.php?ref=pf, or some other such URL designated by us in writing;

As a high-volume user of Facebook, your use of Platform far exceeds some or all of the thresholds in Section II.11 of the Developer Principles and Policies;

You acknowledge that supporting your use of Facebook requires significant operational, technical infrastructure, performance, employee and financial resources. Accordingly, in order to be able to continue to support your use of Facebook, we need to invest significant additional resources to help ensure the continued stability and reliability of our services.

You wish to assist us in our effort to help us provide our users with a safe, secure, simple and efficient experience on Facebook. In furtherance of such efforts, you agree to comply with the terms of this Addendum and cooperate with us in our efforts to encourage the adoption of Facebook Credits.

Accordingly, the parties mutually agree to the terms and conditions of this Addendum. This Addendum supplements the SRR as set forth herein.

Capitalized terms not defined in this Addendum or its Exhibits have the meanings given to them in the SRR.

For mutual and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, we and you agree as follows:

Agreement

1. API. Subject to your continued compliance with this Addendum and the SRR, during the Term, we will provide you with access to our public APIs that we generally make available to all other developers. For purposes of clarity, nothing herein obligates us to provide you with access to any distribution channels (e.g., requests, bookmarks, streams) for any Zynga Services or Covered Zynga Services.

2. Facebook Ad Units.

a. Implementation of Facebook Ad Units. Subject to the terms herein, beginning on a date to be determined by us (the "Facebook Ad Unit Launch Date") and continuing for so long as we wish to utilize Facebook Ad Units (defined below) during the remainder of the Term, you will enable us to display advertising purchased by a third party or other advertising purchased by us ("Content") through an iFrame (or some other functionality or technology that is mutually agreed upon by the parties in writing) provided by us that shall appear on Zynga Game Pages (and only Zynga Game Pages) on which you decide to implement such iFrame (the "Facebook Ad Unit") (all such Zynga Game Pages, "Properties"). We will provide you with ninety (90) days prior written notice in the event that we elect to cease serving Content through Facebook Ad Units for display on the Properties.

b. Conditions and Restrictions Relating to Facebook Ad Units. The following conditions and restrictions apply to Facebook Ad Units on Properties:

(i) Each Facebook Ad Unit you implement shall (1) appear on the right hand side of the web page of all Properties so the user is not required to scroll horizontally to see the Facebook Ad Unit, and (2) be subject to and comply with the same dimension and substantially the same position and placement requirements that we use for and apply to third party advertisements placed on Canvas Pages as of the Effective Date, as such dimension, positioning and placement requirements are depicted and described in Exhibit F. You acknowledge and agree that we will be the "executive producer" of all Facebook Ad Units. Accordingly, and subject to Section 2.b (vii) below, you agree that we will have sole control over the appearance, design, layout, look-and-feel, Content (including adding, changing or removing Content), advertisers whose Content appear within, features, and functionality of all Facebook Ad Units and the methods and means used to monetize Facebook Ad Units.

(ii) You must have and abide by an appropriate privacy policy. Your privacy policy should also include information about user options for cookie management.

(iii) You agree to comply with commercially reasonable specifications provided by us from time to time to enable proper delivery, display, tracking, and reporting of Content and to enable proper tracking and reporting of impressions, clicks and other actions taken in connection with Content.

(iv) You agree to direct to us, and not to any advertiser, any communication regarding any Content displayed in connection with Facebook Ad Units.

(v) You are solely responsible for the Properties, including all content and materials, maintenance and operation thereof and the proper implementation of our specifications. We are not responsible for anything related to Properties except for the serving of Content that appears in the Facebook Ad Units implemented on such Properties.

(vi) You will not (a) directly or indirectly generate impressions, clicks, or any other user engagement with Content through any automated, deceptive, fraudulent or other invalid means, including through repeated manual clicks, the use of robots or other automated tools or software; (b) modify or change in any way any Content; (c) use any interstitial, pop-up windows, other intermediate steps or any other technology or content which acts as a barrier to the transition of a user from any Facebook Ad Unit to any web page or other location accessed by an end user after clicking on any Content ("Page"); (d) remove, minimize, frame, or otherwise inhibit the full and complete display of any Page; (e) display any Content on any web page or web site that contains pornographic, hate-related, violent or illegal content; (f) redirect an end user away from any Page or provide a version of any Page that is different from the page an end user would access by going directly to the Page, intersperse any content between the Content and the Page; or otherwise provide anything other than a direct link from Content to a Page; (g) directly or indirectly access, launch, and/or activate Content through or from any software application, web site, or other means other than Properties and then only to the extent expressly permitted by this Section 2.b(vii); and (h) index, "crawl", "spider" or in any non-transitory manner store or cache information obtained from any Content. In addition, you will not facilitate or encourage any of the foregoing. Notwithstanding

anything to the contrary herein, we acknowledge that you may offer users the option to play games that are Covered Zynga Services in full screen mode, so long as such option shall be presented to a user in a manner that is not materially more prominent than the implementation of such option on Covered Zynga Services as of the Effective Date and as reflected in Exhibit G.

(vii) You agree not to display on the same web page on which any Facebook Ad Unit or Content is displayed, any advertisement(s) or content that an end user of any Properties would reasonably confuse with one of our advertisements or otherwise associate with us (e.g., by utilizing our branding or using the same font or branding elements used in the Facebook Ad Unit).

(viii) We will not serve any advertisement (A) for any Named Entity or (B) that disparages you or (C) that contains pornographic, hate-related, violent or illegal content, or (D) that contains animation, in each case within any Facebook Ad Unit displayed on any Properties. In the event we do serve any such advertisement described in the foregoing (A) – (D), you will notify us and, as your sole and exclusive remedy, we will promptly remove the advertisement, but in no event within more than [*] following receipt of such notification. In the event that we serve any Facebook Ad Unit that causes a material degradation in or otherwise materially impedes the functionality of any of your Properties, as your sole and exclusive remedy, you will be entitled to remove the Facebook Ad Unit and you will notify us immediately of such removal. You will reinstate the removed Facebook Ad Unit within 12 hours of us notifying you that we have cured the issue giving rise to the applicable material degradation or material impediment.

(ix) We represent and warrant that, for the calendar month of April 2010, the average RPM for advertisements shown in connection with Covered Zynga Services on your Canvas Pages is [*].

(x) [*] Notwithstanding the foregoing, we may allow advertisers to choose not to place ads on your Properties or third party websites in general. You acknowledge and agree that if we offer any third party the ability to display advertising on its website as part of an official advertising network using iFrames that are larger than the Facebook Ad Unit, doing so shall not be deemed a breach of this Section 2.(x), and we agree to offer you the same larger iFrame format.

(xi) We will provide advertisement partner management support to drive advertising revenue derived from Facebook Ad Units.

(xii) You acknowledge and agree that certain Content may, when clicked upon or otherwise engaged with by a user, render or generate an overlay, pop-up, or interactive functionality (collectively, an "Overlay"), and you hereby agree not to block, inhibit, impede, or interfere with the rendering, performance, or use of any such Overlay. You acknowledge and agree that the rendering of an Overlay in and of itself does not constitute a material degradation in, or a material impediment of, the functionality of any of your Properties.

3. Fees.

a. Within 15 days of the end of each month of the Term you shall send us a report that (1) identifies the specific Properties on which you implemented the Facebook Ad Unit during the previous month and (2) the number of Page Views generated during the previous month of all Zynga Game Pages on which a Facebook Ad Unit was not implemented ("Monthly Page View Count").

b. Each month during the Term, for all Properties on which you implemented, during the previous month, the Facebook Ad Unit, we will pay you a percentage of Net Revenue ("Ad Share") arising from such Properties for the previous month. Such Ad Share will be [*]. Notwithstanding anything to the contrary in this Addendum, we shall not be liable for any payment identified by us within [*] after the date of such payment as having been based on: (a) any amounts which result from fraud, invalid queries or invalid clicks or impressions on Content generated by any person, bot, automated program or similar device, as reasonably determined by us, including without limitation through any clicks or impressions (i) originating from your IP addresses or computers under your control, (ii) solicited by payment of money,


		3		*Confidential Treatment Requested.

false representation, or request for end users to click on Content, or (iii) solicited by payment of money, false representation, or any illegal or otherwise invalid request for end users to complete events; (b) Content delivered to end users whose browsers have JavaScript disabled; (c) placeholder or transparent Content that we may deliver; or (d) clicks co-mingled with a significant number of invalid clicks described in (a) above, or as a result of any breach of this Addendum by you for any applicable pay period. We reserve the right to withhold payment or charge back your account due to any of the foregoing pending our reasonable investigation of any of the foregoing (provided that such investigation shall not exceed [*], or in the event that an advertiser whose Content is displayed in connection with Properties defaults on payment for such Content to us. Our records and figures, as determined by us using our tracking methodologies will be used to determine all Ad Share payments and will govern in all circumstances.

c. For each month during the Term after the Facebook Ad Unit Launch Date in which we served Content for display on the Properties, for all Zynga Game Pages on which you did not, during the previous month, implement the Facebook Ad Unit (other than as a result of the removals made pursuant to Section 2.b(viii)), you will pay us an amount equal to [*]. In no event shall the foregoing monthly payment exceed [*] for any given month. Each payment made by you pursuant to this Section 3.c will be accompanied by a detailed report verifying amounts paid and the manner in which payments were calculated. Each such report shall include such categories of data and level of detail as mutually agreed upon by the parties. Within fourteen (14) days of the date of any written request by us, you shall verify and certify in a writing signed by one of your senior executives your compliance with your payment obligations under Section 3.c. We may request any such certification no more than once each quarter during the Term.

d. Each month during the Term, you shall have the right, but not the obligation, to display Facebook Ad Units on game-related forums and game related web pages that are owned and operated by Zynga or its Affiliates that are not Zynga Game Pages. Your display of Facebook Ad Units on any other web pages that are not Zynga Game Pages shall be subject to our prior written approval on a case by case basis (which we may withhold at our sole discretion). For the sake of clarity, in the event that Facebook Ad Units are displayed on any such web pages, the provisions of Sections 2, 3.a and 3.b shall apply.

e. Each payment made by us pursuant to Section 3.b will be accompanied by a detailed report verifying amounts paid and the manner in which such amounts were calculated. Each such report shall include such categories of data and level of detail as mutually agreed upon by the parties. Within fourteen (14) days of the date of any written request by you, we shall verify and certify in a writing signed by one of our senior executives our compliance with our payment obligations under Section 3.b. You may request any such certification no more than once each quarter during the Term.

4. Implementation of Facebook Credits.

a. Implementation of Facebook Credits in Covered Zynga Services. You shall begin implementing (and you shall cause your Affiliates to begin implementing) Facebook Credits in all Covered Zynga Services commencing on the Implementation Start Date set forth in Exhibit B for each such Covered Zynga Service. You shall complete implementation (and you shall cause your Affiliates to complete implementation) of Facebook Credits in all Covered Zynga Services by no later than the Exclusivity Start Date set forth in Exhibit B for each such Covered Zynga Service. Within thirty (30) days after the Effective Date, the parties will mutually agree on a detailed written implementation plan that is consistent with the dates set forth on Exhibit B ("Implementation Plan"); provided, however, you acknowledge and agree that any failure by the parties to agree on the Implementation Plan will not affect or reduce any of your obligations under this Addendum including, without limitation, your obligations under Section 4.b. The Implementation Plan may only be accelerated upon mutual agreement of the parties. Notwithstanding anything to the contrary in this Addendum, you acknowledge and agree that we reserve the right to slow down the pace at which you implement Facebook Credits in any or all Covered Zynga Services by pushing back the Exclusivity Start Dates or the staging set forth in the Implementation Plan, with the understanding that the Exclusivity Start Date for each such Covered Zynga Service will be extended by the number of days by which we extend the staging of the implementation of Facebook


		4		*Confidential Treatment Requested.

Credits. Except as set forth in the foregoing sentence, any changes to Exhibit B must be mutually agreed upon by the parties in writing. Without limiting Section 4.b. of this Addendum, once you (or your Affiliates) begin implementing Facebook Credits in any Covered Zynga Service, you shall not (and you shall cause your Affiliates not to) remove Facebook Credits from such Covered Zynga Service unless we request otherwise in writing. Notwithstanding anything to the contrary in this Addendum, you acknowledge and agree that, no more frequently than [*] (the "Removal Cap"), we may request you (or any of your Affiliates) to remove Facebook Credits from, and to cease using Facebook Credits in connection with, any Covered Zynga Services at any time at our sole discretion upon written notice to you, and you shall comply with (and you shall cause your Affiliates to comply with) each such request within [*] of any such request. In the event of any request by us to remove Facebook Credits completely from any Covered Zynga Services, Section 4.b shall no longer apply to such Covered Zynga Service, and you shall be entitled to use any alternative Payment Method in place of Facebook Credits, until the date on which we instruct you in writing to once again include Facebook Credits in such Covered Zynga Service(s), which we may do at our sole discretion, at which point Section 4.b will once again apply in full force and effect to said Covered Zynga Service(s) within twenty four (24) hours of such instruction being made. Notwithstanding anything to the contrary herein, you acknowledge and agree that the Removal Cap shall not apply to any requests by us for you to remove Facebook Credits from any Covered Zynga Services for breaches or violations by you (or any of your Affiliates) of this Addendum or the SRR.

b. Facebook Credits Exclusivity for Covered Zynga Services.

(i) You acknowledge and agree that Facebook Credits will be the sole and exclusive Payment Method that is used, accepted or otherwise made available on or in connection with all Covered Zynga Services during the Term. Subject to Section 4.a, this exclusivity obligation will commence with respect to each of the Covered Zynga Services set forth in Exhibit B on the Exclusivity Start Date set forth therein and will continue for the remainder of the Term for so long as such Covered Zynga Service remains a Covered Zynga Service. For each Covered Zynga Service that is created after the Effective Date or offered or otherwise made available to any third party for the first time after the Effective Date, the exclusivity obligations set forth in this Section 4.b. will commence for such Covered Zynga Service on the date such Covered Zynga Service is first offered or otherwise made available (or some other date as mutually agreed by you and us by way of a written amendment to this Addendum) and will continue for the remainder of the Term, provided that in the event that you acquire a Covered Zynga Service from a third party (whether by merger, stock purchase, asset acquisition or otherwise), you will provide us written notice thereof, and the exclusivity obligations set forth in this Section 4.b will commence for such Covered Zynga Service on that date that is [*] after the closing date of the applicable transaction. Within fourteen (14) days of the date of any written request by us, you shall verify and certify in a writing signed by one of your senior executives your (and your Affiliates') compliance with the terms of this Section 4.b. We may request such certification no more than once per each quarter of the Term.

(ii) Notwithstanding anything to the contrary in Section 4.b(i), the parties acknowledge and agree that Section 4.b(i) shall be subject only to the following limited exceptions set forth in this Section 4.b(ii):

(1)

If, for any individual Covered Zynga Service, Facebook Credits cannot be used by users of such Covered Zynga Service (an "Impacted Covered Zynga Service") for a period of [*] due to a technical error and such inability to use Facebook Credits is not caused by any acts or omissions of you or any of your Affiliates or the systems or technology of you or any of your Affiliates (such [*] outage a "Facebook Credits Outage"), as your sole and exclusive remedy, you shall notify us of the Facebook Credits Outage by sending a screenshot of the outage via email to an email address designated by us to enable us to verify the Facebook Credits Outage, and, beginning on [*] and continuing only for so long as Facebook Credits cannot be used by users of an Impacted Covered Zynga Service due to such Facebook Credits Outage, you may use any alternative Payment Method in place of Facebook Credits (a "Substitute Payment Method") to complete purchases made by users within all Impacted Covered Zynga Services. You shall replace the Substitute Payment Method with Facebook Credits within [*] following your receipt of notice (email acceptable) from us that Facebook Credits is capable of being used (such notice, the "Replacement Notice"); provided, however, if you are unable to do so within such time period,


		5		*Confidential Treatment Requested.

you will notify us (email acceptable) and you shall complete such replacement within [*] of your receipt of the Replacement Notice during normal business hours, and within [*] of your receipt of the Replacement Notice outside of normal business hours. You shall comply with the requirements set forth herein for each Facebook Credits Outage that occurs. The messaging you display or send to users related to Facebook Credits Outages shall be subject to our prior review and written approval, not to be unreasonably withheld or delayed, provided that you may display or send to users any messaging that is substantially similar to messaging already approved by us in accordance with this Section 4.b.(ii)(1) without seeking our prior review and approval. Such messaging may only be displayed to users of the Impacted Covered Zynga Service who have attempted or are attempting to make a purchase while a Facebook Credits Outage is occurring and who experience the Facebook Credits Outage.

(2)

You may use a Payment Method that is not Facebook Credits to complete purchases made within Covered Zynga Services by users of such Covered Zynga Services that reside in any country in which we prohibit, pursuant to the SRR, residents of such country to purchase Facebook Credits from us (a "Restricted Country"). In the event we remove any such prohibition, without limiting Section 4.b(i), you will use Facebook Credits as the sole and exclusive Payment Method for purchases made by users of Covered Zynga Services that that reside in any Restricted Country in accordance with Section 4.b(i) above within thirty (30) days of receipt of written notice from us.

(3)	Notwithstanding anything to the contrary in Section 4.b(i):

(a)

Your Gift Cards. Subject to the terms herein, we acknowledge that your distribution of Gift Cards [*] is not a violation of Section 4.b(i), provided that all Gift Cards that are redeemable on Covered Zynga Services may be redeemed only for Facebook Credits.

As used herein, "Gift Card(s)" mean a stored value gift card that is redeemable on Covered Zynga Services and/or Other Zynga Services.

Subject to Section 4.b(ii)(3)(d) below, to enable you to use Gift Cards as a Payment Method for Facebook Credits in Covered Zynga Services in accordance with this Section 4.b(ii)(3)(a), we will sell you Facebook Credits [*]. You shall then resell to users [*] in transactions using such Gift Cards on Covered Zynga Services. You assume all risk of loss for and shall be solely responsible for, all fraud, returns, refunds, reversals, fines, chargebacks and other such fees arising from or relating to the resale by you of Facebook Credits pursuant to this Section 4.b(ii)(3)(a) or Section 4.b(ii)(3)(b).

For the avoidance of doubt, this Section 4.b(ii)(3)(a) is not intended to and shall not preclude you from offering and redeeming Gift Cards that are redeemable only on Other Zynga Services [*].

(b)

Permitted Third Party Payment Options. In the event we do not offer, and only until such time as we begin to offer, Wire Transfers or any of the payment options set forth on Exhibit D hereto ("Permitted Third Party Payment Options") as a Payment Method for Facebook Credits, we will allow you to offer within Covered Zynga Services such Permitted Third Party Payment Option to end users directly for the sole and exclusive purpose of enabling such end users to purchase Facebook Credits from you using such Permitted Third Party Payment Option; provided, however, you acknowledge and agree that Wire Transfers may be used solely to complete individual purchases from you of Facebook Credits that are in excess of [*].

Subject to Section 4.b(ii)(3)(d) below, if applicable, to enable you to use Permitted Third Party Payment Options as a Payment Method for Facebook Credits in Covered Zynga Services in accordance with this Section 4.b(ii)(3(a), we will sell you Facebook Credits [*] which you shall then resell to users [*] using Permitted Third Party Payment Option. We agree that we will, within a commercially practicable time period, implement and maintain

a high volume mechanized process in order to implement the applicable provisions of this Section 4.b(ii)(3)(b). We acknowledge that use of Permitted Third Party Payment Options in accordance with this Section 4.b(ii)(3)(b) is not a violation of Section 4.b(i). As used herein, "Wire Transfer" means a same day irrevocable electronic transfer of funds between banks by electronic means.

Notwithstanding anything to the contrary herein, you acknowledge and agree that we may restrict or limit your ability to offer or use Permitted Third Party Options to the extent we reasonably believe necessary to prevent or respond to fraudulent activity or money laundering, or as required by law.

(c)

[*].

(d)

Zynga In-Game Currency. We acknowledge and agree that (i) you are entitled to use Zynga In-Game Currency in accordance with this Addendum and all applicable laws, provided that to the extent Zynga In-Game Currency is sold or purchased in or in connection with Covered Zynga Services, such Zynga In-Game Currency must be sold and purchased via Facebook Credits and will be subject to Section 4.b(i); (ii) your continued use of Zynga In-Game Currency in Covered Zynga Services in accordance with this Addendum during the Term is not a violation of Section 4.b(i); and (iii) we will not require you to denominate items sold in Covered Zynga Services in Facebook Credits (for purposes of clarity, and subject to Section 4.b(ii), Zynga In-Game Currency used in Covered Zynga Services must be purchasable using Facebook Credits only). "Zynga In-Game Currency" means any currency that is developed and maintained solely by or on behalf of you and offered solely by you or any of your Affiliates. For purposes of clarity, no third party currencies will be Zynga In-Game Currencies. You acknowledge and agree that each Zynga In-Game Currency that is used in a Covered Zynga Service: (a) may not be used in any other Covered Zynga Service, with the exception of experience points that are earned only through game play and are not purchased with any Payment Method; (b) may not be converted into or redeemed for any other Zynga In-Game Currency or any other currency including, without limitation, cash, any cash equivalents, or the experience points described in (a) of this subsection; (c) may not be given by a user to another user within any Covered Zynga Services, provided that the limitation in this subsection (c) shall not apply to the winning and losing of poker chips in a poker game play or to any gift that is not deducted from the gifting user's balance; (d) may not be used or accepted by any third party.

(e)

6. Operating Guidelines. Without limiting any of our rights under the SRR, in an effort to minimize the strain you place on our systems, from time to time we may, at our sole discretion, establish restrictions or operating guidelines and procedures governing your use of Facebook provided such guidelines and procedures are generally applicable to other developers (collectively, "Operating Guidelines").

b. Either party may terminate (without penalty to the terminating party arising from such termination) this Addendum or the SRR upon written notice to the other party if the other party materially breaches any term of this Addendum or materially breaches or materially violates any term or provision of the SRR and such party fails to cure any such breach or violation within 30 days of receipt of written notice of such breach from the non-breaching party (such thirty (30) day period, the "Breach Cure Period"). You acknowledge that if any such breach or violation by you is a breach or violation of any term or provision of the SRR or Addendum relating to the storing, caching, deletion, transferring, acquiring, disclosing, selling or displaying of user data or is a violation of any term or provision of the SRR that requires you to comply with applicable laws, then we may, in addition to our termination remedy, at our sole discretion, cease providing you with access to Facebook (including, without limitation, our APIs) during the Breach Cure Period, provided that [*] in a good faith attempt to resolve the issue that gave rise to such breach, provided, further if [*], we may so notify your General Counsel via email and thereafter and immediately cease providing you with access to Facebook (including, without limitation, our APIs).

If the parties are unable to resolve such issue via the Level 2 Escalation, then the CEOs of the parties will meet in person to attempt in good faith to resolve the issue that gave rise to the breach ("Level 3 Escalation"). A party may only terminate this Addendum if the parties have been unable to resolve the issue via the Level 3 Escalation within thirty (30) days of written notice of the breach. Any deletion by you (or your Affiliates) of your account (or the accounts of your Affiliates) or any disabling by you (or any of your Affiliates) of any Covered Zynga Services will not limit or affect your obligations under this Addendum.
