Anything in this License to the contrary notwithstanding, Licensor and Licensee hereby waive and release each other of and from any and all Claims of each party for any loss or damage that may occur to the Premises, Building and/or the personal property of each party within the Building, but only to the extent the releasing party’s loss or damage is covered under casualty insurance policies in effect at the time of such loss or damage or would have been covered by the casualty insurance required to be carried under this Section 5 had the releasing party complied with its applicable insurance obligations under this Section 5. Each party agrees to promptly give to its respective insurance company which has issued policies of insurance covering any risk of direct physical loss, written notice of the terms of the mutual waivers contained in this Section 5, and to have such insurance policies properly endorsed, if necessary, to prevent the invalidation of said insurance coverage by reason of said waivers.

SECTION 6

NONWAIVER

No provision of this License shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Fees hereunder by Licensor shall not be deemed to be a waiver of any preceding breach by Licensee of any term, covenant or condition of this License, other than the failure of Licensee to pay the particular Fees so accepted, regardless of Licensor’s knowledge of such preceding breach at the time of acceptance of such Fees.

SECTION 7

10.2. Subordination. Without the necessity of any additional document being executed by Licensee for the purpose of effecting a subordination, this License shall be subject and subordinate at all times to ground or underlying licenses and to the lien of any mortgage or deeds of trust now or hereafter placed on, against or affecting the Building, Licensor’s interest or estate in the Building, or any ground or underlying license; provided, however, that if the lessor, mortgagee, trustee, or holder of any such mortgage or deed of trust elects to have Licensee’s interest in this License be superior to any such instrument, then, by notice to Licensee, this License shall be deemed superior, whether this License was executed before or after said instrument, provided further that notwithstanding any such subordination, Licensee shall be entitled to peaceful possession of the Premises and to all of its rights under this License at all times during the License Term hereof so long as Licensee is not in default hereof as provided in Section 11 hereof. Notwithstanding the foregoing, Licensee covenants and agrees to execute and deliver upon demand such further instruments evidencing such subordination or superiority of this License as may be required or requested by Licensor.

SECTION 11

DEFAULTS: REMEDIES

11.1 Events of Default. The occurrence of any of the following shall constitute a default of this License by Licensee:

11.1.1 Any failure by Licensee to pay any Fee or any other undisputed charge required to be paid under this License, or any part thereof, when due unless such failure is cured within [**] business days after written notice to Licensee; or

11.1.2 Except where a specific time period is otherwise set forth for Licensee’s performance in this License, in which event the failure to perform by Licensee within such time period shall be a default by Licensee under this Section 11, any failure by Licensee to observe or perform any other provision, covenant or condition of this License to be observed or performed by Licensee where

such failure continues for [**] days after written notice thereof from Licensor to Licensee; provided that if the nature of such default is such that the same cannot reasonably be cured within a [**] day period, Licensee shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default. The notice periods provided above in this Section 11 are in lieu of, and not in addition to, any notice periods provided by any applicable Laws.

11.2. Remedies Upon Default.

11.2.1 Terminate this License, in which event Licensee shall immediately surrender the Premises to Licensor, and if Licensee fails to do so, Licensor may, without prejudice to any other remedy which it may have for possession or arrearages in fees, enter upon and take possession of the Premises and expel or remove Licensee and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefore.

11.2.2 Licensor shall at all times have the rights and remedies, without prior demand or notice except as required by applicable Laws, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this License, or restrain or enjoin a violation or breach of any provision hereof.

11.3. Efforts to Re-License. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, relicensing, appointment of a receiver to protect Licensor’s interests hereunder, or any other action or omission by Licensor shall be construed as an election by Licensor to terminate this License or Licensee’s right to possession, or to accept a surrender of the Premises.

SECTION 12

LATE CHARGES

12.1. Late Charges. If any installment of Fees or any other sum due from Licensee shall not be received by Licensor or Licensor’s designee within [**] days after said amount is due, then Licensee shall pay to Licensor a late charge equal to [**] percent ([**]%) of the overdue amount plus any reasonable attorneys’ fees incurred by Licensor by reason of Licensee’s failure to pay Fees and/or other charges when due hereunder. The late charge shall be in addition to all of Licensor’s other rights and remedies hereunder and shall not be construed as liquidated damages or as limiting Licensor’s remedies.

12.2. Interest.

13.2. Transfer of Licensor’s Interest. Licensee acknowledges that Licensor has the right to transfer all or any portion of its interest in the Building and in this License, and Licensee agrees that in the event of any such transfer, Licensor shall automatically be released from all liability under this License arising from and after the effective date of the transfer and Licensee agrees to look solely to such transferee for the performance of Licensor’s obligations hereunder arising from and after the date of the transfer and such transferee shall be deemed to have fully assumed and be liable for all such future obligations of Licensor under this License, including the return of any Security Deposit, and Licensee shall attorn to such transferee. Licensee further acknowledges that Licensor may assign its interest in this License to a mortgage lender as additional security and agrees that such an assignment shall not release Licensor from its obligations hereunder and that Licensee shall continue to look to Licensor for the performance of its obligations hereunder.

13.3. Partial Invalidity. If any term, provision or condition contained in this License shall, to any extent, be invalid or unenforceable, the remainder of this License, or the application of such term, provision or condition shall not be affected thereby, and each and every other term, provision and condition of this License shall be valid and enforceable to the fullest extent possible.

INTERCONNECTION FACILITY SERVICE LEVELS

The Interconnection Facility is located on the Fourth (4th) Floor within the One Summer Street Telecom Facility in Boston, Massachusetts. The Interconnection Facility is comprised of two sections, the Equipment Area (comprised of two or more rooms) and the Cross Connect Area.

Upon installation of conduit into the Equipment Area of the Interconnection Facility, Licensees will terminate all fiber into the Licensee’s assigned area. All terminations will be scheduled in writing and the management will coordinate the installations. Terminations will be made during normal business hours. Should Licensee require after hours installation, additional fees laid out in this document will apply.

Cross Connect Area.

All cross connects will be terminated to Bell Core Standards. The connections will be tested by the requesting company. Once connection has been accepted, it will be documented by the Licensor’s OSS System.
