hereto shall use the same degree of care, but no less than reasonable care, to protect the other Party's Confidential Information as it uses to protect its own Confidential Information of like nature. Unless otherwise authorized in any other agreement between the Parties, any Party receiving any Confidential Information of the other Party (the "Receiving Party") may use Confidential Information only for the purposes of fulfilling its obligations under this Agreement (the "Permitted Purpose"). Any Receiving Party may disclose such Confidential Information only to its representatives who have a need to know such information for the Permitted Purpose and who have been advised of the terms of this Section 4.1 and the Receiving Party shall be liable for any breach of these confidentiality provisions by such Persons; provided, however, that any Receiving Party may disclose such Confidential Information to the extent such Confidential Information is required to be disclosed by law, in which case the Receiving Party shall promptly notify, to the extent possible, the disclosing party (the "Disclosing Party"), and take reasonable steps to assist in contesting such disclosure requirement or in protecting the Disclosing Party's rights prior to disclosure, and in which case the Receiving Party shall only disclose such Confidential Information that it is advised by its counsel in writing that it is legally bound to disclose. Notwithstanding the foregoing, "Confidential Information" shall not include any information that the Receiving Party can demonstrate: (a) was publicly known at the time of disclosure to it, or has become publicly known through no act of the Receiving Party or its representatives in breach of this Section 4.1, (b) was rightfully received from a third party without a duty of confidentiality, or (c) was developed by it independently without any reliance on the Confidential Information. 4.2 Return of Confidential Information. Upon demand by the Disclosing Party at any time, or upon expiration or termination of this Agreement with respect to any Service, the Receiving Party agrees promptly to return or destroy, at the Disclosing Party's option, all Confidential Information received in connection with this Agreement. If such Confidential Information is destroyed, an authorized officer of the Receiving Party shall certify to such destruction in writing. 5. Indemnification. 5.1 Indemnification. Provider shall indemnify, defend, and hold harmless Recipient and its officers, directors, employees, agents, affiliates, successors, and permitted assigns (collectively, "Indemnified Party") against any and all losses, damages, liabilities, deficiencies, claims, actions, judgments, settlements, interest, awards, penalties, fines, costs, or expenses of whatever kind, including attorneys' fees, fees and the costs of enforcing any right to indemnification under this Agreement, and the cost of pursuing any insurance providers, incurred by Indemnified Party or awarded against Indemnified Party (collectively, "Losses"), relating to/arising out of or resulting from any claim of a third party or Recipient arising out of or occurring in connection with Provider's negligence, willful misconduct, or breach of this Agreement. Provider shall not enter into any settlement without Recipient's or Indemnified Party's prior written consent. 6. Miscellaneous. 6.1 Entire Agreement. This Agreement, the Purchase Agreement and the documents referred to herein and therein constitute the entire agreement among the Parties and supersedes any prior understandings, agreements, or representations by or among the Parties, written or oral, to the extent they relate in any way to the subject matter hereof. 6 6.2 Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns. Provider may not assign, delegate or otherwise transfer either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of Recipient. 6.3 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which together will constitute one and the same instrument. Counterparts may be delivered via facsimile and electronic mail (including portable document format (PDF) or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com). 6.4 Titles and Headings. Titles and section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement. 7. Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the
