Subject to Publisher’s compliance with all of the terms and conditions of this Agreement, Publisher will be entitled to receive a payment based upon GumGum’s measurements of the revenue that GumGum receives from Served Ads.


Publisher acknowledges and agrees that the number of impressions and clicks relating to Served Ads, used in calculating amounts payable to Publisher, shall be tracked and based solely on GumGum’s data and measurements. GumGum shall provide Publisher with automated and online access to statistics, metrics and data required to calculate the impressions, clicks and any other date necessary to determine the payments due to Publisher, and Publisher reserves the right to dispute determinations made by GumGum in connection with the amounts due to Publisher, including in connection with calculations of impressions or clicks; provided, however, if the difference between GumGum’s and Publisher’s measurements differ by more than ten percent (10%), the parties shall amicably resolve such discrepancy in good faith.


GumGum will send payments to Publisher within sixty (60) days after the last day of each month that Served Ads are placed on Publisher Websites if Publisher’s earned balance is $50 or more.


Notwithstanding the foregoing, GumGum shall have no payment obligation to Publisher with respect to any Served Ads that GumGum does not receive any revenue.


Without limiting the generality of the foregoing, GumGum shall not be liable for any payment based on: (a) any amounts which result from invalid impressions of Served Ads generated by any person, bot, automated program or similar device, as reasonably determined by GumGum including, without limitation, through any impressions (i) originating from Publisher’s IP addresses or computers under Publisher’s control; or (ii) solicited by payment of money, false representation, or any illegal or otherwise invalid request for end users to view Served Ads; (b) Served Ads delivered to end users whose browsers have JavaScript disabled; or (c) impressions resulting from any breach of this Agreement by Publisher for any applicable pay period.

To ensure proper payment, Publisher is solely responsible for providing and maintaining an accurate address and contact information, as well as payment information associated with Publisher’s account.

If Publisher disputes the amount of any payment made under this Agreement, Publisher must notify GumGum in writing of such payment dispute within ninety (90) days following the date such payment was received; failure to timely notify GumGum of a payment dispute shall result in Publisher’s waiver of any claim relating to payable amounts corresponding to the Served Ads for which the disputed payment was made. Amounts payable by GumGum hereunder shall be calculated solely based on data and records maintained by GumGum. No other data, measurements or statistics of any kind shall be accepted by GumGum or have any effect under this Agreement. Publisher’s right to receive payments made under this Agreement may not be transferred or in any manner passed on to any third party unless expressly permitted in this Agreement or authorized in writing by GumGum in advance (such authorization may be given by email).

Upon any termination of this Agreement, Publisher shall promptly remove the GumGum Technology from all Publisher Websites and GumGum shall have no further obligation to provide GumGum Ad Services. Furthermore, GumGum will perform a final accounting of amounts payable to Publisher hereunder and, subject to GumGum’s right to offset the earned balance of amounts due to Publisher against paid amounts determined by GumGum to be in error or the result of fraud or any act by, or at the direction of Publisher, in violation of this Agreement, GumGum will pay the earned balance of amounts due to Publisher hereunder within approximately ninety (90) days following the last day of the month in which this Agreement is terminated.

Termination of this Agreement shall not prejudice GumGum’s rights, defenses and limitations of liability provided under this Agreement, which rights, defenses and limitations of liability shall survive termination of this Agreement.

The following Sections of this Agreement shall survive termination of this Agreement: Sections 1, 5 and 8-17.

In such jurisdictions, the liability of GumGum or any of its affiliates, directors, officers, shareholders, employees, agents, licensors, licensees or advertisers shall be limited to the maximum extent permitted by law.

Any election to arbitrate by one party shall be final and binding on the other. The arbitration will be conducted under the Streamlined Arbitration Rules and Procedures of JAMS that are in effect at the time the arbitration is initiated (the “JAMS Rules”) and under the terms set forth in this Agreement. In the event of a conflict between the terms set forth in this Section 12 and the JAMS Rules, the terms in this Section 16 will control and prevail.


Except as otherwise set forth in Section 16.4, You may seek any remedies available to You under federal, state or local laws in an arbitration action.


As part of the arbitration, both You and GumGum will have the opportunity for discovery of non-privileged information that is relevant to the Claim.


The arbitrator will provide a written statement of the arbitrator’s decision regarding the Claim, the award given and the arbitrator’s findings and conclusions on which the arbitrator’s decision is based.


The determination of whether a Claim is subject to arbitration shall be governed by the Federal Arbitration Act and determined by a court rather than an arbitrator.


Except as otherwise provided in this Agreement, (a) You and GumGum may litigate in court to compel arbitration, stay proceedings pending arbitration, or confirm, modify, vacate or enter judgment on the award entered by the arbitrator; and (b) the arbitrator’s decision shall be final, binding on all parties and enforceable in any court that has jurisdiction, provided that any award may be challenged if the arbitrator fails to follow applicable law.

You and GumGum agree that the following Claims are not subject to the above provisions concerning negotiations and binding arbitration: (a) any Claim seeking to enforce or protect, or concerning the validity of, any of Your or GumGum’s intellectual property rights; and (b) any claim for equitable relief.
