INSURANCE

14.1. Tenant’s Insurance.

(A) Tenant, at Tenant’s expense, shall obtain and keep in full force and effect (i) an insurance policy for Tenant’s Property and the Specialty Alterations, in either case to the extent insurable under the available standard forms of “all-risk” insurance policies, in an amount equal to one hundred percent (100%) of the replacement value thereof (subject, however, at Tenant’s option, to a reasonable deductible) (the insurance policy described in this clause (i) being referred to herein as “Tenant’s Property Policy”), (ii) a policy of worker’s compensation insurance, to the extent required by law (such policy being referred to herein as “Tenant’s Worker’s Compensation Policy”), and (iii) a policy of commercial general liability and property damage insurance on an occurrence basis, with a broad form contractual liability endorsement

(the insurance policy described in this clause (iii) being collectively referred to herein as “Tenant’s Liability Policy”). Tenant’s Property Policy and Tenant’s Liability Policy shall name Tenant as the insured. Tenant’s Property Policy shall also include business interruption insurance that is sufficient in amount to pay the Fixed Rent and the Tax Payment due hereunder for a period of at least one (1) year. Tenant’s Liability Policy shall name the Landlord Indemnitees as additional insureds thereunder.

(B) Tenant’s Liability Policy shall contain a provision that (a) no act or omission of Tenant shall affect or limit the obligation of the insurer to pay the amount of any loss sustained, and (b) the policy is non-cancelable with respect to the Landlord Indemnitees unless at least thirty (30) days of advance written notice is given to Landlord, except that Tenant’s Liability Policy may be cancelable on no less than ten (10) days of advance written notice to Landlord for non-payment of premium. If Tenant receives any notice of cancellation or any other notice from the insurance carrier which may adversely affect the coverage of the insureds under Tenant’s Property Policy or Tenant’s Liability Policy, then Tenant shall immediately deliver to Landlord a copy of such notice. The minimum amounts of liability under Tenant’s Liability Policy shall be a combined single limit with respect to each occurrence in the amount of Five Million Dollars ($5,000,000) for injury (or death) to persons and damage to property, which minimum amount Landlord may increase from time to time to the amount of insurance that in Landlord’s reasonable judgment is then being customarily required by prudent landlords of first- class buildings in the vicinity of the Building from tenants leasing space similar in size, nature and location to the Premises.

(C) Tenant shall cause Tenant’s Liability Policy, Tenant’s Worker’s Compensation Policy and Tenant’s Property Policy to be issued by reputable and independent insurers that are (x) permitted to do business in the State of New York, and (y) rated in Best’s Insurance Guide, or any successor thereto, as having a general policyholder rating of A and a financial rating of at least XII (it being understood that if such ratings are no longer issued, then such insurer’s financial integrity shall conform to the standards that constitute such ratings from Best’s Insurance Guide as of the date hereof).

(D) Tenant has the right to satisfy Tenant’s obligation to carry Tenant’s Liability Policy with an umbrella insurance policy if such umbrella insurance policy contains an aggregate per location endorsement that provides the required level of protection for the Premises. Tenant has the right to satisfy Tenant’s obligation to carry Tenant’s Property Policy with a blanket insurance policy if such blanket insurance policy provides, on a per occurrence basis, that a loss that relates to any other location does not impair or reduce the level of protection available for the Premises below the amount required by this Lease.

14.2. Landlord’s Insurance.

(A) Subject to the terms of this Section 14.2, Landlord shall obtain and keep in full force and effect insurance against loss or damage by fire and other casualty to the Building, to the extent insurable on commercially reasonable terms under then available standard forms of “all-risk” insurance policies, in an amount equal to one hundred percent (100%) of the replacement value thereof or, at Landlord’s option, in such lesser amount as will avoid co-

45

insurance (such insurance being referred to herein as “Landlord’s Property Policy”). Tenant acknowledges that (i) Landlord’s Property Policy may encompass rent insurance, (ii) the risks that Landlord’s Property Policy covers may include, without limitation, fire, war, terrorism, environmental matters, and flood, and (iii) Landlord may also obtain a commercial general liability insurance policy.

(B) Landlord shall not be liable to Tenant for any failure to insure any Alterations unless Tenant notifies Landlord of the completion of such Alterations and the cost thereof, and maintains adequate records with respect to such Alterations to facilitate the adjustment of any insurance claims with respect thereto. Landlord shall have the right to provide that the coverage of Landlord’s Property Policy is subject to a reasonable deductible. Tenant shall cooperate with Landlord and Landlord’s insurance companies in the adjustment of any claims for any damage to the Building or the Alterations. Landlord shall not be required to carry insurance on Tenant’s Property or the Specialty Alterations. Landlord shall not be required to carry insurance against any loss suffered by Tenant due to the interruption of Tenant’s business.

14.3. Mutual Waiver of Subrogation.

(A) Subject to the provisions of this Section 14.3, Landlord and Tenant shall each obtain an appropriate clause in, or endorsement on, Landlord’s Property Policy or Tenant’s Property Policy (as the case may be) pursuant to which the insurance companies waive subrogation or consent to a waiver of right of recovery. Landlord and Tenant also agree that, having obtained such clauses or endorsements of waiver of subrogation or consent to a waiver of right of recovery, they shall not make any claim against or seek to recover from the Landlord Indemnitees or the Tenant Indemnitees (as the case may be) for any loss or damage to its property or the property of others resulting from fire or other hazards covered by Landlord’s Property Policy or Tenant’s Property Policy (as the case may be); provided, however, that the release, discharge, exoneration and covenant not to sue herein contained shall be limited by and be coextensive with the terms and provisions of the waiver of subrogation clause or endorsements or clauses or endorsements consenting to a waiver of right of recovery.

(B) If the payment of an additional premium is required for the inclusion of a waiver of subrogation provision as described in Section 14.3(A) hereof, then each party shall advise the other party of the amount of any such additional premiums and the other party at its own election may, but shall not be obligated to, pay such additional premium. If (x) Tenant is the party that elects to pay such additional premium to include such a waiver in Landlord’s Property Policy, and (y) other tenants in the Building make concurrently a similar election, then the aforesaid amount that Tenant is obligated to pay to Landlord on account of such additional premium shall be only the portion thereof that Landlord allocates equitably to Tenant. If such other party does not elect to pay such additional premium, then the party whose insurer is charging the additional premium shall not be required to obtain such waiver of subrogation provision.

(C) If either party is unable to obtain the inclusion of such waiver of subrogation provision even with the payment of an additional premium, then such party shall attempt to name the other party as an additional insured (but not a loss payee) under the

46

applicable insurance policy. If the payment of an additional premium is required for naming the other party as an additional insured (but not a loss payee), then such party shall advise the other of the amount of any such additional premium and the other party at its own election may, but shall not be obligated to, pay such additional premium. If (x) Tenant is the party that elects to pay such additional premium to name Tenant as an additional insured (but not as loss payee), and (y) other tenants in the Building make concurrently a similar election, then the aforesaid amount that Tenant is obligated to pay to Landlord on account of such additional premium shall be only the portion thereof that Landlord allocates equitably to Tenant. If such other party does not elect to pay such additional premium or if it is not possible to have the other party named as an additional insured (but not loss payee), even with the payment of an additional premium, then (in either event) the party whose insurer refuses to include such waiver of subrogation provision shall so notify the other party and such party shall not have the obligation to name the other party as an additional insured.

14.4. Evidence of Insurance.

On or prior to the Commencement Date, each party shall deliver to the other party appropriate certificates of insurance required to be carried by the parties pursuant to this Article 14, including evidence of waivers of subrogation and naming of additional insureds in either case as required by Section 14.3 hereof. Each party shall deliver to the other party evidence of each renewal or replacement of a policy at least twenty (20) days prior to the expiration of such policy.

14.5. No Concurrent Insurance.

Tenant shall not obtain any property insurance (under Tenant’s Property Policy or otherwise) that covers the property that is covered by Landlord’s Property Policy.

14.6. Tenant’s Obligation to Comply with Landlord’s Fire and Casualty Insurance.

If (i) Tenant (or any other Person claiming by, through or under Tenant) uses the Premises for any purpose other than general office use , and (ii) the use of the Premises by Tenant (or such other Person) causes the premium for Landlord’s Property Policy to exceed the premium that would have otherwise applied therefor if Tenant (or such Person) used the Premises for general office use, then Tenant shall pay to Landlord, as additional rent, an amount equal to such excess, on or prior to the thirtieth (30th) day after the date that Landlord gives to Tenant an invoice therefor, together with reasonable supporting documentation for the charges set forth therein. Nothing contained in this Section 14.6 expands Tenant’s rights under Article 3 hereof.
