Agreement the transferor shall cease to be liable for, and shall be released
from all liability for the performance and observance of, any and all agreements

--------------------------------------------------------------------------------

 

  h)   Services: All services, goods and other offerings of any kind to be
provided by Sentinel to Customer pursuant to this Agreement as set forth in an
Order.

2)   License Terms and Responsibilities of the Parties.

  a)   Sentinel owns a so-called data center (the “Sentinel Bedford Data
Center”) located at 55 Middlesex Turnpike, Bedford, Massachusetts (the
“Property”), at which Sentinel provides space and provides certain related data
center facility services to businesses. Upon payment of the applicable fees and
subject to the terms and conditions herein, Sentinel (i) grants Customer a
license (sometimes herein the “License”) for the License Term to use the
distinct areas (hereinafter, the “Space”) of the Sentinel Bedford Data Center
described in Attachment 1 attached hereto and identified in any Sales Order
separately signed by Sentinel and Customer, including any Sales Order hereafter
signed, the License to be solely for the purpose of installing, operating,
maintaining, altering and repairing in the Space equipment which will at all
times belong to Customer or its third party supplier and will not belong to
Sentinel (“Equipment’’), and (ii) shall provide certain services that are set
forth in an Order (each such service, a “Service”). If Sentinel and Customer
subsequently sign any new Sales Orders, the Space identified in that Sales Order
shall ipso facto become part of the “Space” for all purposes under this
Agreement. For purposes of this Agreement, the License is acknowledged to be a
Service.     b)   At all times during the Term, Sentinel and Customer agree to
comply with the rules, regulations and procedures set forth in the Occupant
Handbook, which rules, regulations and procedures are at all times incorporated
by reference into this Agreement. Customer acknowledges that it has received a
copy of the current Occupant Handbook prior to execution of this Agreement.    
c)   Customer acknowledges that the License is only to use the Space for the
Permitted Use, and that Customer has not been granted any rights of real
property or other interests in the Space or the Property.     d)   Sentinel
acknowledges that Customer’s assets are subject to a lien in favor of Silicon
Valley Bank (together with any other institutional Sender to Customer from time
to time a “Bank”), Sentinel agrees that it will execute and deliver to the Bank
such documents, instruments and agreements requested by Bank from time to time,
acknowledging Bank’s security interests in Customer’s assets, granting Bank
access, as limited in such document, instrument or agreement to such assets, and
addressing such other matters required by Bank. Provided that all damage caused
by such removal shall be promptly repaired, Customer may remove any or all of
its assets from the Space and the Property at any time, in its sole discretion,
and Sentinel agrees to provide Customer with access to remove such assets, upon
Customer’s request from time to time.

3)   No Use of Space by Others.

Customer may not sublicense the Space or any portion thereof or permit any
occupancy or use thereof or access thereto by anybody other than Customer or its
Affiliates and their agents, employees and contractors, nor may Customer assign
or otherwise transfer its

2

--------------------------------------------------------------------------------

 

interest in this Agreement, except that Customer may assign this Agreement
without consent (but with notice to Sentinel promptly after or contemporaneous
with such assignment) (i) to an Affiliate (or may so sublicense to an Affiliate)
or (ii) in connection with a merger, consolidation, reorganization or sale of
all or substantially all of its assets, provided in each instance that the
transferee or sublicense, immediately after such transaction (and taking into
account assets and liabilities acquired through such transaction), shall have
financial resources, in terms of net worth and working capital, at least equal
to that of Customer as of the date of such transfer or sublicense or as of the
MSA Effective Date, whatever shall be greater. Any act in connection of the
foregoing shall be deemed ipso facto null and void.

4)   Insurance; Waiver of Subrogation; SAS 70 Report; Indemnity.

  a)   Customer shall throughout the term hereof maintain commercial general
liability insurance with respect to the Space and its occupancy and use of the
Property, issued by well-rated insurance companies authorized to do business in
the Commonwealth of Massachusetts, in amounts not less than Ten Million Dollars
($10,000,000.00) with, respect to bodily injuries suffered in any one occurrence
and not less than Five Million Dollars ($5,000,000.00) with respect to property
damage.     b)   The insurance required to be carried by Customer pursuant to
this License may be carried under a blanket policy, and Customer shall provide
to Sentinel, upon the execution of this Agreement and thereafter prior to the
expiration of each such policy, evidence of the maintenance of the insurance
required pursuant to this Article 4.     c)   Sentinel shall throughout the term
hereof maintain commercial general liability insurance with respect to the
Property, issued by well-rated insurance companies authorized to do business in
the Commonwealth of Massachusetts, in amounts not less than Ten Million Dollars
($10,000,000.00) with respect to bodily injuries suffered in any one accident
and not less than Five Million Dollars ($5,000,000.00) with respect to property
damage. Such insurance required to be carried by Sentinel pursuant to this
Agreement may be carried under a blanket policy, and Sentinel shall provide to
Customer, upon Customer’s written request, evidence of the maintenance of the
insurance required pursuant to this Article 4.     d)   Neither Sentinel nor
Customer shall have any obligation to insure any property belonging to or in the
possession of the other. As to any property insurance carried by Sentinel on the
Property where the Space is located, Sentinel shall obtain a waiver of
subrogation in favor of Customer. As to any property insurance carried by
Customer on its Equipment, Customer shall obtain a waiver of subrogation in
favor of Sentinel. Except as set forth in subsection (d) immediately below,
neither party shall have any responsibility for any loss or damage to property
belonging to or in the possession of the other.     e)   Sentinel shall, as soon
as reasonably practicable and in no event later than the first anniversary of
the MSA Effective Date, provide to Customer a Type II SAS 70 audit report (the
“SAS 70 Report”) with respect to the data center operations and services
provided at the Sentinel Bedford Data Center and the Property. The SAS 70 Report

3

--------------------------------------------------------------------------------

 

      shall be issued by an accounting firm with a nationally recognized
reputation and reasonably satisfactory to Customer (provided that Customer
agrees that Wolf & Co. shall be deemed so satisfactory). Following the delivery
of the first SAS 70 Report to Customer, Sentinel shall thereafter furnish an SAS
70 Report to Customer on an annual basis. In the event Sentinel fails to deliver
to Customer a SAS 70 Report, as required under this subparagraph (e), within
twenty (20) days after receipt of notice from Customer of Sentinel’s failure to
do so as above provided, then Customer shall have the right to terminate this
Agreement upon thirty (30) days prior written notice to Sentinel provided
Sentinel shall have failed to deliver such SAS 70 Report within such thirty
(30) days.     f)   Subject to the limitations on the liability of each party
elsewhere contained in this Agreement, each party (the “Indemnifying Party”)
shall defend, indemnify and hold harmless the other party (the “Indemnified
Party”) from and against (i) any and all third party claims for loss, cost
damage, liability or expense (including, without limitation, attorneys’ fees and
expenses) in any way arising out of or related to any breach or alleged breach
by the Indemnifying Party under this Agreement; or (ii) any negligent act or
omission or misconduct of the Indemnifying Party, its employees, or agents. The
Indemnifying Party’s obligations hereunder are contingent on the following
conditions: (i) the Indemnified Party must notify the Indemnifying Party in
writing promptly after the Indemnified Party becomes aware of a claim or the
possibility thereof; (ii) the Indemnified Party must grant the Indemnifying
Party the sole control (but subject to consultation from time to time with the
Indemnifying Party) of the settlement compromise, negotiation and defense of any
such claim; and (iii) the Indemnified Party must cooperate with the Indemnifying
Party and provide the Indemnifying Party with all information related to the
claim that is reasonably requested by the Indemnifying Party.

5)   Interruptions in Service, and Intrusive Testing.

Sentinel shall use all reasonable commercial efforts to minimize errors and
interruptions in the Services and to provide advance notice of any
unavailability of Services, even if caused by force majeure. In all events
Sentinel’s liability for any failure of Services shall be limited as elsewhere
provided in this Agreement. Services may be temporarily unavailable by reason of
force majeure or as set forth in Section 13d hereof. Notwithstanding anything in
this Agreement to the contrary, if Customer shall give Sentinel notice (an
“Abatement Notice”) of an Abatement Event (as that term is defined below), and
if such Abatement Event continues thereafter beyond the Eligibility Period (as
that term is defined below), then the Recurring Charges to Customer shall be
abated entirely or proportionately reduced, as the case may be, after expiration
of the Eligibility Period for such time that Customer continues to be so
prevented from using, and does not use, the Space, or a portion thereof, for the
conduct of any of Customer’s business. The term “Eligibility Period” shall mean
a period of seven (7) consecutive days after Sentinel’s receipt of any Abatement
Notice(s). An “Abatement Event” shall be defined as an event or circumstance
that prevents Customer from using the Space, or a material portion thereof, as a
result of any failure by Sentinel to provide the Services set forth in
Attachment 2, or to have access to the Space needed by Customer to utilize the
Services, even if caused by force majeure. In addition, if an Abatement Event
prevents Customer from using all or substantially all of

4

--------------------------------------------------------------------------------

 

the Space in a manner consistent with the parameters set forth in this Agreement
and the attachments hereto, and such Abatement Event continues for more than six
(6) months after an Abatement Notice with respect thereto, Customer may
terminate this Agreement by thirty days’ written notice to Sentinel, unless such
Abatement Event is cured during such thirty day period. In addition, at any time
during an Abatement Event Customer may request that Sentinel provide written
notice of whether Sentinel has the intention and expectation that such Abatement
Event will be corrected within six (6) months after the original Abatement
Notice with respect thereto. Sentinel shall provide a written response to such
request (an “Assurance Response”) within ten (10) days of such request. If
Sentinel does not deliver to Customer an Assurance Response in such timeframe
that indicates that Sentinel expects that the Abatement Event will be corrected
prior to six (6) months after the original Abatement Notice with respect
thereto, then Customer may terminate this Agreement by thirty days’ written
notice to Sentinel, unless such Abatement Event is cured during such thirty day
period.

6)   Term of Agreement, Termination, and Default.

  a)   This Agreement shall commence on the MSA Effective Date. Unless earlier
terminated in accordance with its terms, this Agreement will terminate on the
date the last Sales Order then in effect expires or is terminated pursuant to
the terms and conditions set forth in this Agreement (which will be the date on
which the last “License Term” as specified and defined on such last Sales Order
expires or is terminated pursuant to the terms and conditions of this
Agreement).     b)   If either party shall be in material breach of this
Agreement (nonpayment of any money due under an invoice or otherwise hereunder
being agreed to be deemed ipso facto a material breach of this Agreement), or if
Customer shall be in material breach of any of the rules regulations and
procedures set forth in the Occupant Handbook, or if Sentinel shall modify
materially the Occupant Handbook in a manner unacceptable to Customer in its
reasonable discretion, the other party may terminate (at its discretion) this
Agreement as to any or all Space (including all Services associated with that
Space) then covered hereunder, upon thirty (30) days’ prior written notice to
the breaching party unless the breaching party shall cure such breach prior to
the expiration of such thirty (30) day period or, if cure cannot be reasonably
achieved within such thirty (30) day period, the breaching party commences cure
and diligently prosecutes such cure to completion at all times thereafter
(provided, however, that such time period shall be ten (10) days with respect to
any failure on the part of Customer to pay any charges hereunder). Termination
shall not, however, except to the extent otherwise provided herein, be the sole
remedy under this Agreement, and, whether or not termination is effected, except
as expressly limited in this Agreement (including the limitations on the
liability of Sentinel contained elsewhere in this Agreement), all other remedies
will remain available. If the Property becomes the subject of an eminent domain
or condemnation action by any authority or person that has such power and if
continued operation of the Property for the Permitted Use would thereafter be
impractical or impossible, or if Sentinel’s or Customer’s possession or right of
access is otherwise terminated or substantially abated, either party shall have
the right to terminate this Agreement. Either party may also terminate this
Agreement by giving written notice of termination to the other party if (i) the
other party becomes the subject of a voluntary petition in

5

--------------------------------------------------------------------------------

 

      bankruptcy or any voluntary proceeding relating to insolvency,
receivership, liquidation, or composition for the benefit of creditors; or
(ii) the other party becomes the subject of an involuntary petition in
bankruptcy or any involuntary proceeding relating to insolvency, receivership,
liquidation or composition for the benefit of creditors and if such involuntary
petition or proceeding is not dismissed within sixty (60) days after filing,
provided in each case that Customer shall have such right to terminate this
Agreement only if as a result of such petition or proceeding the Sentinel
Bedford Data Center is no longer able to operate in a manner sufficient to allow
Customer to receive the Services or to use the Space for the Permitted Use.    
c)   Upon termination of this Agreement with respect to any particular Space,
the License and all other rights of Customer with respect to such Space, and the
right to receive Services associated with such Space, shall terminate, and
Customer agrees to remove the Equipment and any other property belonging to
Customer prior to the effective time of such termination. If Customer fails to
so remove the Equipment and all such other property Sentinel shall be entitled
to pursue all available legal remedies against Customer, including, without
limitation, immediately removing the Equipment and all such other property from
the Space and storing it at Customer’s expense at an off- site location. At
Sentinel’s option, Sentinel may sell the Equipment and other property to cover
storage and other expenses if Customer fails to retrieve the Equipment and other
property and pay all accrued storage and other expenses within thirty (30) days
after receiving written notice from Sentinel of the intention of Sentinel to
effect such sale.     d)   Should the Space or the Sentinel Bedford Data Center
be substantially damaged by fire or other casualty, then Customer or Sentinel
may elect to terminate this Agreement, provided that Customer shall not have
such right to terminate if Sentinel gives notice of its intention to restore
within forty-five (45) days following such fire or casualty and substantially
restores the Space to a condition suitable for the Permitted Use within six
(6) months after the date of such notice of intent to restore. Customer shall
have no obligation to pay any Recurring Charges on a proportionate basis, for
any period during which the Space or any portions thereof is not usable by
Customer on account of such fire or other casualty.

7)   Price and Payment Terms.

  a)   Customer shall pay Sentinel recurring monthly charges (hereinafter
“Recurring Charges”), and other charges and deposits set forth in each Order, in
accordance with Section (b) immediately below. Customer’s obligation to pay
Recurring Charges shall commence for any Sales Order as set forth therein.
Customer shall also pay Sentinel’s then current charges for any site preparation
or other work undertaken by Sentinel pursuant to an Order or otherwise at
Customer’s request (“Installation Charges”).     b)   Customer shall pay to
Sentinel all Recurring Charges without notice or demand, in lawful money of the
United States, in monthly installments in advance on the first (1st) day of each
calendar month during the applicable term. With respect to all other charges,
Customer invoices will be sent by Sentinel monthly and payment shall be due
within twenty (20) days of Customer’s receipt of each invoice. Without

6

--------------------------------------------------------------------------------

 

      intending to derogate from any other remedies available to Sentinel,
undisputed amounts past due will incur a finance charge at the rate of 1% per
month, or the maximum monthly interest rate permitted by law, whichever is
lower, applied to the amount past due. All payments will be made in U.S.
dollars.     c)   Customer shall pay directly all taxes, governmental fees, and
third-party charges related to the ownership and operation of the Equipment and
the activities of Customer at the Sentinel Bedford Data Center, and shall be
responsible for the payment, through Sentinel if such be the applicable party,
of all taxes and other such charges upon the Recurring Charges and any other
charge hereunder. Notwithstanding anything to the contrary in the foregoing,
however. Sentinel agrees that Sentinel shall be responsible for all property and
use taxes applicable to the Space and all income taxes relating to amounts paid
to Sentinel hereunder.

8)   Time and Materials Services.

     Should Customer choose to use the time and materials services (described in
Attachment 1 hereto or in any Sales Order) offered by Sentinel. Customer shall
pay the charges from time to time in effect for such services, in each case
within twenty-seven (27) days of receipt of Sentinel’s invoice. Sentinel
reserves the right to require that Customer sign an additional agreement
relating to such services. The only obligation of Sentinel with respect to such
services shall be to carry out the express instructions of Customer, to the
extent agreed to by Sentinel. In the event that Sentinel fails to correctly
carry out any such instructions of Customer, Customer’s sole remedy shall be to
require Sentinel to not charge Customer for the portion of the service not
correctly performed or to correct such work. It is the parties’ intention that
this Agreement shall be a so-called “gross” license except for Recurring Charges
and Installation Charges and Sentinel’s services payable pursuant to Attachments
1 and 2, and this Article 8 and Article 7 immediately above, and that Customer
shall have no obligation to otherwise pay any additional proration costs or
charges for operating expenses, real estate taxes, insurance or other such
items.

9)   Representations, Warranties and Limitation of Liability.

  a)   Except as expressly otherwise provided in this Agreement or in an Order,
Sentinel provides the Space, the Sentinel Bedford Data Center, and the Services
strictly on an “as is, as available” basis, and Customer’s use of Data Center
Services is at Customer’s own risk. Except as expressly provided herein,
Sentinel does not make, and hereby expressly disclaims, any and all warranties,
expressed or implied, including but not limited to any warranty of
merchantability or fitness for a particular purpose.     b)   Notwithstanding
anything to the contrary contained in this Agreement, neither party shall be
responsible or liable under or with respect to this Agreement, under any
contract, tort, strict liability or other theory, from any cause, (a) for error
or interruption of use or for loss or inaccuracy or corruption of data or cost
of procurement of services or technology or for relocation expenses or loss of
business: (b) for any indirect, exemplary, incidental, special, consequential or
other such damages, including, but not limited to, loss of profits: or (c) for
any force majeure event, as provided in Section 13d hereof. In all events
Sentinel’s total liability for damages to customer for any cause whatsoever,
regardless of the form of action, and

7

--------------------------------------------------------------------------------

 

      whether in contract, tort, strict liability or other theory, from any
cause, for any period in which the space is unavailable or cannot be used or any
period during which services have not been furnished shall be limited to the
Recurring Charges attributable to such monthly period. The provisions of this
section 9(b) shall not be deemed to limit either party’s liability for breach of
Section 10 or 11 of this Agreement.     c)   Each party represents and warrants
to the other that (a) it has obtained all necessary consents, licenses, leases,
permits, and other approvals, both governmental and private, as may be necessary
to permit it to perform its obligations under this Agreement; and (b) it has the
full right and authority to enter into, execute, deliver and perform its
obligations under this Agreement.     d)   Each representative and each other
person visiting the Sentinel Bedford Data Center does so at his/her own risk,
and Sentinel assumes no liability whatsoever for any harm to such persons
resulting from any cause resulting in personal injury to such persons or damage
to any property of such persons during such a visit, except to the extent
arising out of the gross negligence or willful misconduct of Sentinel or its
agents, employees or contractors.     e)   Notwithstanding anything to the
contrary in this Agreement, each party’s maximum aggregate liability to the
other party for monetary damages related to or in connection with this Agreement
shall be limited to the amount of the Recurring Charges paid or payable by
Customer to Sentinel hereunder for the then-prior six (6) months, provided that
during the first eighteen (18) months of the term of this Agreement such limit
shall be the greater of such prior six months’ Recurring Charges or Four Hundred
Thousand Dollars ($400,000.00), and provided that in all events such limitation
shall not apply to Customer’s obligations to pay Sentinel Recurring Charges and
all other charges under this Agreement. Each party’s only other remedies shall
be as specifically provided in this Agreement, except that for damages arising
from the gross negligence or willful misconduct of a party, such party’s maximum
aggregate liability to the other party for monetary damages arising from such
gross negligence or willful misconduct shall be the amounts of insurance payable
by the insurance carrier(s) on behalf of such party for such damages, provided
that such party shall have been carrying at least the insurance required to be
maintained pursuant to Section 4(a) or 4(b) above, as applicable.

10)   Confidential Information.

  a)   Definition. As used in this Agreement, the term “Confidential
Information” with respect to Customer shall mean any and all non-public
information in any form that is proprietary or confidential to Customer or
Customer’s clients, and for which such non-public and proprietary or
confidential status has been communicated to Sentinel in writing or which, under
the circumstances taken as a whole, would reasonably be deemed to be
confidential, including without limitation all information regarding the
Equipment and all information stored in or transmitted through the Equipment. As
used in this Agreement, the term “Confidential Information” with respect to
Sentinel shall mean, collectively any non-public: (a) business or technical
information, including but not limited to information relating to product plans,
designs, costs.

      product prices and names, finances, marketing plans, business
opportunities, personnel, research, development and know-how; (b) any
information designated and marked in writing by Sentinel as “confidential” or
“proprietary” or which, under the circumstances taken as a whole, would
reasonably be deemed to be confidential; and (c) the terms and conditions of
this Agreement.     b)   General. Each party shall treat as confidential all
Confidential Information of the other party, and shall not use such Confidential
Information except as expressly authorized herein or otherwise authorized in
writing by the other party. Each party shall implement reasonable procedures to
prohibit the disclosure, unauthorized duplication, misuse or removal of the
other party’s Confidential Information, and shall not disclose such Confidential
Information to any third party except as may be necessary or required in
connection with the rights or obligations of such party under this Agreement,
and subject to confidentiality obligations at least as protective as those set
forth herein. Without limiting the foregoing, each of the parties shall use at
least the same procedures and degree of care which it uses to prevent the
disclosure of its own confidential information of like importance to prevent the
disclosure of Confidential Information disclosed to it by the other party under
this Agreement, but in no event less than reasonable care.     c)   Exceptions.
Notwithstanding the above, “Confidential Information” shall not include
information which: (i) was generally known and available in the public domain at

rights; or (vi) as to the existence and terms of this Agreement, is disclosed to
a party proposing to carry out a significant corporate transaction with the
disclosing party (such as a merger, acquisition or major financing) if disclosed
under an agreement requiring generally that the party receiving such information
maintain its confidentiality. Notwithstanding the foregoing, the receiving party
may disclose Confidential Information, to the minimum extent necessary, if such
disclosure is: (i) required to be made pursuant to law or regulation, government
authority, duly authorized subpoena or court order, whereupon the receiving
party shall provide prompt notice to the disclosing party and give such party an
opportunity to respond prior to such disclosure and seek a protective order or
other appropriate remedy, or (ii) is approved by the express prior written
consent of the disclosing party.     d)   Remedies. If either party breaches any
of its obligations with respect to confidentiality and/or unauthorized use of
Confidential Information hereunder, the other party shall be entitled to seek
equitable relief to protect its interest therein, including but not limited to
injunctive relief.

Sentinel shall not access, gather, store, or use any Customer Information in any
manner, and shall not disclose, distribute, sell, share, rent or otherwise

Attachment 2
Service Level Agreement
This Service Level Agreement (sometimes hereinafter “SLA”) is attached to and
forms part of that certain Master Services Agreement (sometimes hereinafter the
“License”) dated as of July 19, 2007, by and between Constant Contact, Inc.
(“Customer”) and Sentinel Properties — Bedford, LLC (“Sentinel”). Unless defined
herein, all capitalized terms in this SLA are defined in the License or exhibits
thereto. Pursuant to the License. Sentinel is licensing to Customer the Space at
the Sentinel Bedford Data Center, and in connection therewith will be providing
services to Customer in order to support Customer’s use of the Space. This SLA
establishes standards for the provision of certain services by Sentinel, and
also provides for Customer to receive a credit against certain fees payable by
Customer under the License in certain situations.
1. Power
If a cabinet containing functioning computer or networking equipment (a “Loaded
Cabinet”) in the Space is powered by two (2) different power distribution units
and both units experience a simultaneous interruption in electrical power, such
that such Loaded Cabinet experiences an interruption in power (a “Power Outage”)
which lasts longer than five (5) consecutive seconds but shorter than one
(1) continuous hour, Sentinel shall credit to Customer’s account the Cabinet
Charges (hereinafter defined) attributable to such Loaded Cabinet, and all other
Loaded Cabinets which are not fully functional as a result of the unavailability
of the Loaded Cabinet that suffered such Power Outage, for the day during which
such interruption occurs. “Cabinet Charges” shall be defined as the Recurring
Charges payable for a given month divided by the number of Loaded Cabinets in
the Space at the time of the outage. If a Loaded Cabinet in the Space is powered
by two different power distribution units and both units experience a
simultaneous interruption in electrical power such that such Loaded Cabinet
experiences a Power Outage which lasts for one (1) continuous hour or longer,
Sentinel shall credit Customer’s account the Cabinet Charges attributable to
that Loaded Cabinet and all other Loaded Cabinets which are not fully functional
as a result of the unavailability of the Loaded Cabinet that suffered such Power
Outage, for the calendar week during which such interruption occurs.
2. Cooling and Humidity
The Space is designed to provide a target operating temperature of an average of
72 degrees Fahrenheit (at the intake side of properly positioned computing
equipment) and relative humidity ranging from 35 to 65 percent (near the intakes
of on-floor air handlers), provided Customer has properly spaced and configured
computing hardware and loaded and balanced power distribution equipment. Under
normal operating conditions, when there is no indication of individual server or
rack temperature conditions, temperature and humidity will be monitored by
Sentinel in more than one location in the Space to ensure compliance with the
targeted operating ranges.
SLA Measurement and Credit:
Upon recognition of a heat condition affecting devices in a specific area,
Customer may request specific measurement of temperature and/or humidity in that
area. Sentinel shall then place probes in the affected area. For purposes of
this SLA, the temperature will be measured between four (4) and five (5) feet
from the floor and twelve (12) inches to fourteen (14) inches from the cool air
intake side of a cabinet. For this purpose, the temperature reading shall be an
average of the temperature across five contiguous cabinets.

23

--------------------------------------------------------------------------------

 

Humidity will be measured near the air return intake of the air handler units
closest to the measured cabinets.
(i) Temperature
If the temperature as measured above exceeds 80 degrees Fahrenheit for more than
fifteen (15) consecutive minutes and causes (i) a material degradation in the
operation of Customer’s equipment, (ii) Customer’s equipment to fail, or
(iii) Customer to shut down the equipment (a “Temperature Irregularity”) any
time during a calendar month, Sentinel shall credit Customer’s account the
Recurring Charges attributable to the calendar week during which the last
Temperature Irregularity shall have occurred.
(ii) Humidity
If the humidity inside the Space drops below 35 percent or exceeds 65 percent of
the targeted operating range for more than fifteen (15) consecutive minutes (a
“Humidity Irregularity”) two (2) times during a calendar month, Sentinel shall
credit to Customer’s account the Recurring Charges attributable to the calendar
week during which the last Humidity Irregularity shall have occurred.
3. Credits
Notwithstanding anything to the contrary contained in this SLA, the maximum
aggregate credit to which Customer shall be entitled pursuant to this SLA in a
calendar year shall not exceed three months’ Recurring Charges.
With respect to the standards and penalties set forth herein relating to
electrical power and temperature and humidity, penalties shall not be incurred
during any periods in which Sentinel is performing normal and customary
maintenance on equipment serving Customer’s Space, all of which shall be
conducted between the hours of 2:00 AM and 5:00 AM EST, or otherwise during
so-called “off hours.”
Exceptions and Conditions
Sentinel shall exercise reasonable efforts to ensure service level commitments
are met; however, nothing contained in this SLA or in the License shall be
construed to constitute a service level guarantee with respect to acts outside
of Sentinel’s reasonable control.
In addition, Sentinel’s service level commitments stated herein shall not apply
if Sentinel’s failure to meet the standards set forth in this SLA (a) results
from any actions or inactions of Customer or its employees, agents,
representatives or guests; or (b) results from Customer’s Property or improper
or imprudent placement of Customer’s Property.
Customer acknowledges and agrees that except for the termination rights granted
to Customer in the MSA or this SLA, the service level credits under this SLA are
Customer’s sole and exclusive remedy in the event of Sentinel failure to meet
the service level commitments set forth in this SLA or elsewhere in the MSA.
4. Notification
Credit will be given as provided above only if Customer notifies Sentinel in
writing not later than one (1) week after the occurrence of the event entitling
Customer to a credit. Unless otherwise designated by Sentinel, Sentinel can be
reached as indicated in Section 1 of the Occupant Handbook.

24

--------------------------------------------------------------------------------

 

5. Major Outages
If three (3) or more Major Outages (as defined below) shall occur in any three
(3) month period, then Customer may terminate this Agreement by written notice
to Sentinel at any time within ninety (90) days after the third such Major
Outage, which termination shall be effective thirty (30) days after receipt of
notice thereof by Sentinel. A “Major Outage” shall mean any Power Outage that
lasts for at least ten (10) consecutive minutes and/or any Temperature
Irregularity, in each case causing inoperability of Customer’s Equipment.
If any single Major Outage shall continue for three days (a “Prolonged Major
Outage”), such Prolonged Major Outage shall be deemed for purposes of this
Section 5 to be one additional Major Outage, and each subsequent three day’s
duration of a Prolonged Major Outage shall be deemed an additional Major Outage.
Notwithstanding the foregoing, no single Major Outage, regardless of its
duration, shall be deemed a Prolonged Major Outage if Sentinel is using its
commercially reasonable efforts to remedy such outage and in so doing is acting
in a manner consistent with that of an operator of mission critical data
centers. In addition, Sentinel agrees to provide twice daily progress reports on
the restoration of service efforts during any Major Outage until such service is
restored.

25
