Rent Abatement. In the event of a Casualty affecting the Premises, there shall be an equitable adjustment of Base Rent, Operating Costs and Taxes based upon the degree to which Tenant’s ability to conduct its business in the Premises is impaired by reason of such Casualty from and after the date of a Casualty, and continuing until the following portions of the repair and restoration work to be performed by Landlord, as set forth above, are substantially completed: # any repair and restoration work to be performed by Landlord within the Premises, and # repair and restoration work with respect to the Common Areas to the extent that damage to the Common Areas caused by such Casualty materially adversely affects Tenant’s use of, or access to, the Premises.

RENT ABATEMENT. Base Rent for months 2-5 shall be abated by 50% per Paragraph 52 above. CAMs are due in full during Rent Abatement period.

Rent Abatement. As long as Tenant is not in default under the terms of the Lease, rent for the Expansion Premises shall be abated for the first seven (7) months following the Expansion Commencement Date.

Abatement of Rent. In the event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, for ​ (the "Eligibility Period") as a result of any repair, maintenance or alteration performed by Landlord to the Premises after the Commencement Date, which substantially interferes with Tenant's use of the Premises, or any failure to provide services or access to the Premises due to Landlord's default, then Tenant's rent shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises. However, in the event that Tenant is prevented from conducting, and does not conduct, its business in any portion of the Premises for a period of time in excess of the Eligibility Period, and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the rent for the entire Premises shall be abated; provided, however, if Tenant reoccupies and conducts its business from any portion of the Premises during such period, the rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date such business operations commence. To the extent Tenant shall be entitled to abatement of rent because of damage or destruction pursuant to Section 14 or a taking pursuant to Section 15, then the terms of this Section 8.9 shall not be applicable.

Rent Abatement. In the event of a Casualty affecting the Premises, there shall be an equitable adjustment of Base Rent, Operating Costs and Taxes based upon the degree to which Tenant’s ability to conduct its business in the Premises is impaired by reason of such Casualty from and after the date of a Casualty, and continuing until the following portions of the repair and restoration work to be performed by Landlord, as set forth above, are substantially completed: # any repair and restoration work to be performed by Landlord within the Premises, and # repair and restoration work with respect to the Common Areas to the extent that damage to the Common Areas caused by such Casualty materially adversely affects Tenant’s use of, or access to, the Premises.

Abatement of Rent. In the event that: # there shall be an interruption, curtailment or suspension of any service or failure to perform any obligation required to be provided or performed by Landlord pursuant to Sections 9 and/or 10 (and no reasonably equivalent alternative service or supply is provided by Landlord) that shall materially interfere with Tenant’s use and enjoyment of the Premises, or any portion thereof (any such event, a “Service Interruption”), and # such Service Interruption shall continue for three (3) consecutive business days following receipt by Landlord of written notice (the “Service Interruption Notice”) from Tenant describing such Service Interruption (“Abatement Service Interruption Cure Period”), and # such Service Interruption shall not have been caused by an act or omission of Tenant or Tenant’s agents, employees, or contractors (an event that satisfies the foregoing conditions (i)-(iii) being referred to hereinafter as a “Material Service Interruption”) then, Tenant, subject to the next following sentence, shall be entitled to an equitable abatement of Rent based on the nature and duration of the Material Service Interruption and the area of the Premises affected, for any and all days following the Material Service Interruption Cure Period that the Material Service Interruption is continuing and # Tenant does not use such affected areas of the Premises for a bona fide business purpose. Any efforts by Tenant to respond or react to any Material Service Interruption, including, without limitation, any activities by Tenant to remove its personal property from the affected areas of the Premises, shall not constitute a use that precludes abatement pursuant to this Section 10.7(a). The Abatement Service Interruption Cure Period shall be extended by reason of any delays in Landlord’s ability to cure the Service Interruption in question caused by Force Majeure, provided however, that in no event shall the Abatement Service Interruption Cure Period with respect to any Service Interruption be longer than fifteen (15) consecutive business days after Landlord receives the applicable Service Interruption Notice.

Except for the negligence or willful act of Tenant or its agents, employees, contractors or invitees, if all or any part of the Premises are rendered untenantable by fire or other casualty and this Lease is not terminated, Monthly Base Rent and Rent Adjustments shall abate for that part of the Premises which is untenantable on a per diem basis from the date of the casualty until Landlord has Substantially Completed the repair and restoration work in the Premises which it is required to perform, provided, that as a result of such casualty, Tenant does not occupy the portion of the Premises which is untenantable during such period.

Abatement of Rent. If the Premises are damaged by Casualty, Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the completion of Landlord's repairs (or until the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be), unless the gross negligence or willful misconduct of a Tenant Party caused such damage, in which case, Tenant shall continue to pay Rent without abatement.

Rent Abatement. If Landlord fails to perform the obligations required of Landlord under the terms of this Lease and such failure causes all or a portion of the Premises to be unusable by, or inaccessible to, Tenant and such failure relates to # the nonfunctioning of the Building HVAC system in the Premises, the interruption of electricity to the Premises, the nonfunctioning of the elevator service to the Premises, or # a failure to provide access to all or a portion of the Premises (including as a result of any work performed by Landlord in or about the Premises or the Building unless in response to Tenant's request or as a result of Tenant's breach of this Lease), Tenant shall give Landlord notice to the Building management office and the other Landlord notice addresses set forth in Section 11 of the Summary (the "Initial Failure Notice"), specifying such failure to perform by Landlord (the "Abatement Event"). The address for the Building management office is currently 360 Third Street, Suite 105, San Francisco, California 94107, provided that Landlord may change such address and its other notice addresses from time to time by notice to Tenant. If Landlord has not cured such Abatement Event within three (3) business days after the receipt of the Initial Failure Notice (the "Eligibility Period"), Tenant may deliver an additional notice to Landlord (the "Additional Failure Notice"), specifying such Abatement Event and Tenant's intention to abate the payment of Rent under this Lease. If Landlord does not cure such Abatement Event within three (3) business days of receipt of the Additional Failure Notice, Tenant may, upon written notice to Landlord, immediately abate Rent payable under this Lease for that portion of the Premises rendered unusable or inaccessible and not used by Tenant, for the period beginning on the expiration of the Eligibility Period to the earlier of the date Landlord cures such Abatement Event or the date Tenant recommences the use of such portion of the Premises. Such right to abate Rent shall be Tenant's sole and exclusive remedy at law or in equity for an Abatement Event. Except as provided in this [Section 6.4], nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.
