Confidentiality: Each party shall hold the Confidential Information (as hereinafter defined) of the other party in strict confidence and shall not use, or disclose such information to any person, except as explicitly permitted by this Shared Space Arrangement. In protecting the Confidential Information, each party shall use the same degree of care as each party uses to protect its own confidential information of a similar nature (but in no event less than a reasonable degree of care) and shall notify the other party of any potential or actual unauthorized disclosure or use of its Confidential Information.

(i)

Each party may disclose the other party’s Confidential Information to:

(1) its agents and employees only to the extent reasonably necessary to accomplish the purposes of this Shared Space Arrangement and only with the express agreement by such employees and agents that the Confidential Information is to be maintained under confidentiality and nonuse obligations that are no less protective than those in this Shared Space Arrangement; and

(2) to the extent required by applicable law, court order, or in any litigation in connection with this Shared Space Arrangement.

(ii) If either party is required to disclose any of the other party’s Confidential Information pursuant to Section 7(i) above, such party will, if permitted, provide the party whose Confidential Information is being disclosed with reasonable, prior notice of the requirement and assistance (at such party’s expense) so that the party that is the owner of the Confidential Information may seek to oppose the requirement to disclose or obtain a protective order preserving the confidentiality of any of its Confidential Information so disclosed.

(iii) “Confidential Information” shall mean: (a) all business information heard, seen or in any manner learned by either party or its respective agents, employees or Visitors (defined below) due to the parties’ shared use of the Premises; (b) all information that has been or may be disclosed to either party, its employees, or agents orally or in writing, by the other party, its respective employees or agents in connection with, or incidental to, this Shared Space Arrangement or any other business dealing between Licensor and Licensee; and (c) the terms of this Shared Space Arrangement.

The Confidential Information shall not include information that (i) is or becomes available to the public through no fault of a party or its respective agents, employees or Visitors, or (ii) the receiving party can show by written records was acquired in good faith on a non-confidential basis from a third party. “Visitors” shall mean: all persons permitted to access the Premises by or because of either party.

Each party shall be directly liable to the other party for breaches of the confidentiality obligations set forth herein by the receiving party and its respective employees, agents and Visitors. Upon a disclosing party’s request, the receiving party shall destroy, ▇▇▇▇▇, or return to the disclosing party, in a manner reasonably acceptable to the disclosing party, all Confidential Information in its possession or control.

Each party hereby acknowledges and agrees that money damages alone would be an inadequate remedy for the injuries and damage that would be suffered and incurred by either disclosing party as a result of a breach of any of the confidentiality provisions of this Shared Space Arrangement. Accordingly, a disclosing party shall be entitled to equitable relief, including injunctive relief and specific performance, to prevent or end a breach of the confidentiality provisions of this Shared Space Arrangement without the need to show

irreparable harm or to submit proof of the economic value of any Confidential Information. Such equitable relief shall not be deemed to be the exclusive remedy for any breach of this Shared Space Arrangement, but shall be in addition to all other remedies at law or in equity.

Each party’s obligations of confidentiality and nonuse of the Confidential Information under this Shared Space Arrangement shall survive the termination of this Shared Space Arrangement.

Insurance: Licensee shall carry and maintain the same insurance policies and in such amounts that are applicable to Licensor under the Prime Lease, and Licensee shall have Licensor and Prime Landlord named as additional insureds under such policies.

Notice: If a demand, request, appeal, consent or notice (collectively referred to as a “notice”) shall or may be given in accordance with this Shared Space Arrangement, the notice shall be given in writing by physical mail, or by e-mail, to one or more responsible parties, provided that there is a reasonable record kept thereof as relating to both the date of the communication and as to the content thereof. Such a reasonable record can include printed or electronic copies of said communications. Any notice that is sent by mail shall be deemed received, if properly addressed, three (3) business days after any such notice is deposited in the United States mail certified, postage-prepaid, return-receipt requested. If Licensee’s address as set forth below is given as blank or as being within the Premises, then notice shall be deemed received if delivered by hand to the company’s mailbox within the Premises. Any notice under this Shared Space Arrangement that is sent by e-mail shall be deemed received, if delivered to the e-mail address set forth below or, if to Licensee, another e-mail address reasonably believed by Licensor as being that of a responsible party of Licensee, three (3) business days after any such notice is sent, provided that no automatic response has been received from the recipient’s e-mail system indicating non-receipt of the e-mail message or unavailability of the recipient. No oral communication shall be deemed a notice under this Shared Space Arrangement.
