Except as hereinafter expressly permitted, none of the following (each, a “Transfer”), either voluntarily or by operation of Applicable Laws, shall be directly or indirectly performed without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed: # Tenant selling, hypothecating, assigning, pledging, encumbering or otherwise transferring this Lease or subletting the Premises or # a controlling interest in Tenant being sold, assigned or otherwise transferred (other than as a result of shares in Tenant being sold on a public stock exchange). For purposes of the preceding sentence, “control” means # owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person or # possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person. Tenant shall have the right, without Landlord’s prior written consent, to # Transfer Tenant’s interest in this Lease or the Premises or any part thereof to any person that # acquires all or substantially all of the assets of Tenant (either indirectly through a sale of all or substantially all of Tenant’s stock or equity interests or directly), # is a successor to Tenant by merger, consolidation or reorganization or as a result of an initial public offering of Tenant’s stock on a nationally recognized stock exchange, or # as of the date of determination and at all times thereafter directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with Tenant (the transferee or resulting Tenant described in (i), (ii) or (iii), a “Tenant’s Affiliate”) and # provided that, at all times prior to and after such transfer, Tenant remains the tenant under this Lease and Tenant retains the power to direct or cause the direction of the management and policies of Tenant and Tenant retains fifty-one percent (51%) or more of the voting power of all the stock or other equity interests in Tenant, transfer (directly or indirectly) more than fifty percent (50%) of the stock or equity interests of Tenant as part of a bona fide private equity placement financing (an “Equity Financing Transfer”); provided that, in each case, Tenant shall notify Landlord in writing at least thirty (30) days prior to the effectiveness of such Transfer (any such Transfer described in (y) or (z) in this Section above, an “Exempt Transfer”) and otherwise comply with the requirements of this Lease regarding such Transfer; and provided, further, that the person that will be the tenant under this Lease after the Exempt Transfer has a net worth (as of both the day immediately prior to and the day immediately after the Exempt Transfer) that is equal to or greater than the net worth (as of the date of the Exempt Transfer) of the transferring Tenant. For purposes of the immediately preceding sentence, “control” requires both # owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person and # possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person. In no event shall Tenant perform a Transfer to or with an entity that is a tenant at the Project or that is in discussions or negotiations with Landlord or an affiliate of Landlord to lease premises at the Project; provided that, Landlord or such affiliate has sufficient space for such entity at the Project. Upon Tenant’s written request, Landlord shall execute and deliver a commercially reasonable form of confidentiality agreement with respect to any information disclosed to Landlord in connection with a proposed Transfer or Exempt Transfer. Notwithstanding the foregoing, if Tenant is precluded by Applicable Law or by contract from giving Landlord prior written notice of an Exempt Transfer, then Tenant will provide Landlord with written notice of the Exempt Transfer as soon as Tenant may do so without violating Applicable Law or the terms of the applicable contract, and if Tenant does not know all of the material terms of the Exempt Transfer at least thirty (30) days prior to its effectiveness, then Tenant will provide Landlord with written notice of the Exempt Transfer no later than five (5) days after Tenant knows all of the material terms of the Exempt Transfer.

Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as "Transfers" and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a "Transferee"). If Tenant desires Landlord's consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the "Transfer Notice") shall include # the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, # a description of the portion of the Premises to be transferred (the "Subject Space"), # all of the terms of the proposed Transfer and the consideration therefor, including calculation of the "Transfer Premium", as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and # current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee's business and proposed use of the Subject Space. Any Transfer made without Landlord's prior written consent shall, at Landlord's option, be null, void and of no effect, and shall, at Landlord's option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord's reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys', accountants', architects', engineers' and consultants' fees) incurred by Landlord (not to exceed $3,500 in the aggregate for any particular Transfer), within thirty (30) days after written request by Landlord.
