 -27- 








 
Revolving Credit Loans or the Maximum Drawing Amount, all outstanding Reimbursement Obligations, plus all outstanding Swingline Loans, plus all
outstanding Bid Rate Loans, shall not at any time exceed the Total Commitment and provided, further, that at the time the Borrower requests a Revolving Credit Loan and after giving effect to the making thereof: (i) in the case of
any borrowing, all of the conditions in §13 (and in the case of any initial borrowing or other extension of credit on the Closing Date, also the conditions in §12) have been met at the time of such request, and (ii) there has not
occurred and is not continuing (or will not occur by reason thereof) any Default or Event of Default; it being acknowledged and agreed that the Borrower shall be permitted to request and borrow Loans if a Non-Material Breach (rather than a Default
or Event of Default) exists. 
 The Revolving Credit Loans shall be made pro rata in accordance with each Bank’s
Commitment Percentage. Each request for a Revolving Credit Loan made pursuant to §2.4 shall constitute a representation and warranty by the Borrower that the conditions set forth in §12 have been satisfied (except to the extent any such
condition has been waived and/or deferred in writing by the Agent and the required number of Banks) as of the Closing Date and that the conditions set forth in §13 have been satisfied (except to the extent any such condition has been waived
and/or deferred in writing by the Agent and the required number of Banks) on the date of such request and will be satisfied (except to the extent any such condition has been waived and/or deferred in writing by the Agent and the required number of
Banks) on the proposed Drawdown Date of the requested Loan or issuance of Letter of Credit, as the case may be, provided that the making of such representation and warranty by the Borrower shall not limit the right of any Bank not to lend if
such conditions have not been met. No Revolving Credit Loan or other extension of credit shall be required to be made by any Bank unless (in connection with the initial Revolving Credit Loan or Letter of Credit or other extension of credit) all of
the conditions contained in §12 have been satisfied (except to the extent any such condition has been waived and/or deferred in writing by the Agent and the required number of Banks) as of the Closing Date and unless all of the conditions set

 §2.2. The Revolving Credit Notes. The Revolving Credit Loans shall be evidenced by the Revolving Credit Notes. A Revolving
Credit Note shall be payable to the order of each Bank in an aggregate principal amount equal to such Bank’s Commitment. The Borrower irrevocably authorizes each Bank to make or cause to be made, at or about the time of the Drawdown Date of any
Revolving Credit Loan or at the time of receipt of any payment of principal on such Bank’s Revolving Credit Notes, an appropriate notation on such Bank’s applicable Note Record reflecting the making of such Revolving Credit Loan or (as the
case may be) the receipt of such payment. The outstanding amount of the Revolving Credit Loans set forth on such applicable Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such Bank, but
the failure to record, or any error in so recording, any such amount on such Note Record shall not limit or otherwise affect the rights and obligations of the 

  

 -28- 








 
Borrower hereunder or under any Revolving Credit Note to make payments of principal of or interest on any Revolving Credit Note when due. 
 §2.3. Interest on Revolving Credit Loans; Facility Fee.

the Interest Period with respect thereto (unless earlier paid in accordance with §4.2) at a rate equal to the Eurodollar Rate determined for such Interest Period plus the Applicable Eurodollar Margin. 
 (c) The Borrower unconditionally promises to pay interest on each Revolving Credit Loan in arrears on each Interest Payment Date with
respect thereto. 
 (d) The Borrower agrees to pay to the Agent, for the accounts of the Banks in accordance with their

time of reference, the Debt Rating from the other Rating Agency for purposes of establishing the Facility Fee (bps) shall be the rating level utilized by such other Rating Agency which corresponds to the comparable rating levels set forth in the
table above. In the event the Debt Ratings from the Rating Agencies are not equivalent, the Facility Fee (bps) will be determined (i) based on the higher of the two Debt Ratings if the lower Debt Rating is no more than one level lower than the
higher Debt Rating, and (ii) based on the level that is one rating level higher than the lower Debt Rating if the lower Debt Rating is more than one level lower than the higher Debt Rating. Adjustments in the Facility Fee (bps) based upon a
change in a Debt Rating level shall be effective on the first day following the change in such Debt Rating. 
  

 -29- 








 The Borrower shall notify the Agent in writing of any change in the Debt Rating as and
when such change occurs. 
 The Facility Fee is payable in addition to all other fees due from Borrower in connection with this Agreement and shall be
payable quarterly in arrears on the first Business Day of each calendar quarter for the immediately preceding calendar quarter commencing on the first such date following the Closing Date through the Maturity Date, with a final payment on the
Maturity Date. 
 §2.4. Requests for Revolving Credit Loans. 
 The following provisions shall apply to each request by the Borrower for a Revolving Credit Loan: 
 (i) The Borrower shall submit a Completed Loan Request to the Agent and, following its receipt thereof, Agent shall promptly notify each
Bank of its Commitment Percentage of the requested Revolving Credit Loan as set forth in §2.4(v). Except as otherwise provided herein, each Completed Loan Request shall be in a minimum amount of $2,000,000 or an integral multiple of $100,000 in
excess thereof. Each Completed Loan Request shall be irrevocable and binding on the Borrower and shall obligate the Borrower to accept the Revolving Credit Loans requested from the Banks on the proposed Drawdown Date, unless such Completed Loan
Request is withdrawn (x) in the case of a request for a Eurodollar Rate Loan, at least three (3) Business Days prior to the proposed Drawdown Date for such Loan, and (y) in the case of a request for a Prime Rate Loan, at least one
(1) Business Day prior to the proposed Drawdown Date for such Loan. 
 (ii) Each Completed Loan Request shall be
delivered by the Borrower to the Agent by 11:00 a.m. on any Business Day, and at least one (1) Business Day prior to the proposed Drawdown Date of any Prime Rate Loan, and at least three (3) Business Days prior to the proposed Drawdown
Date of any Eurodollar Rate Loan. 
 (iii) Each Completed Loan Request shall include a completed writing in the form of
Exhibit B hereto specifying: (1) the principal amount of the Revolving Credit Loan requested, (2) the proposed Drawdown Date of such Revolving Credit Loan, (3) the Interest Period applicable to such Revolving Credit Loan, and
(4) the Type of such Revolving Credit Loan being requested. Further, each Completed Loan Request shall contain a certification by Borrower in the form set forth in Exhibit B which certifies (among other things) that, both before and after
giving effect to such requested Revolving Credit Loan or Letter of Credit, no Default or Event of Default exists or will exist and that after taking into 

  

 -30- 








 
account such requested Revolving Credit Loan or Letter of Credit, no Default or Event of Default will exist as of the Drawdown Date. 
 (iv) No Bank shall be obligated to fund any Revolving Credit Loan or issue any Letter of Credit unless: 
 (a) a Completed Loan Request has been timely received by the Agent as provided in subsections (i)-(iii) above; and 
 (b) both before and after giving effect to the Revolving Credit Loan to be made or Letter of Credit to be issued pursuant to the Completed
Loan Request, all of the conditions contained in §12 shall have been satisfied (to the extent such conditions have not been waived and/or deferred in writing by the Agent and the required number of Banks prior to the initial advance) as of the
Closing Date, with respect to the initial advance only, and all of the conditions set forth in §13 shall have been met, including, without limitation, the condition under §13.1 that there be no Default or Event of Default. 
 (v) The Agent will use its best efforts to notify each Bank of Agent’s receipt of a Completed Loan Request on the same day it is
received by the Agent and will, absent circumstances outside of its control, so notify each Bank on the Business Day following the day a Completed Loan Request is received by Agent. 
 (vi) In the event that, on any Drawdown Date, after giving effect to the requested Loan or Letter of Credit, Consolidated Total
Indebtedness will exceed 60% (without exceeding 65%) of Consolidated Total Adjusted Asset Value or Unsecured Consolidated Total Indebtedness will exceed 60% (without exceeding 65%) of Consolidated Unencumbered Asset Value, then Borrower shall also
attach to the Completed Loan Request (or the request for a Swingline Loan or Bid Rate Advance Borrowing Notice, as applicable), the certificate attached hereto as Exhibit G, in accordance with §§10.1 and 10.4. 
 §2.5. Conversion Options. 
 (a) The Borrower may elect from time to time to convert any outstanding Revolving Credit Loan to a Revolving Credit Loan of another Type, provided that (i) with respect to any such conversion of a
Eurodollar Rate Loan to a Prime Rate Loan, the Borrower shall give the Agent at least three (3) Eurodollar Business Days’ prior written notice of such election, which notice must be received by the Agent by 11:00 a.m. on any Business Day;
(ii) subject to the proviso at the end of this §2.5(a) and subject to §2.5(b) and §2.5(d), with respect to any conversion of a Prime Rate Loan 

  

 -31- 








 
to a Eurodollar Rate Loan, the Borrower shall give the Agent at least three (3) Eurodollar Business Days’ prior written notice of such election,
which notice must be received by the Agent by 11:00 a.m. on any Business Day; and (iii) no Loan may be converted into a Eurodollar Rate Loan when any Default or Event of Default has occurred and is continuing. Following receipt of such notice
from the Borrower, Agent shall promptly notify each Bank of such request by Borrower. All or any part of outstanding Revolving Credit Loans of any Type may be converted as provided herein, provided that each Conversion Request relating to the
conversion of a Prime Rate Loan to a Eurodollar Rate Loan shall be for an amount equal to $2,000,000 or an integral multiple of $100,000 in excess thereof and shall be irrevocable by the Borrower. 
 (b) Any Revolving Credit Loan of any Type may be continued as such upon the expiration of the Interest Period with respect thereto
(i) in the case of Prime Rate Loans, by compliance by the Borrower with the notice provisions contained in §2.5(a)(ii) and (ii) in the case of Eurodollar Rate Loans, subject to the proviso at the end of this §2.5(b) and
§2.5(d), automatically as set forth in §2.5(c), or by compliance by the Borrower with the notice provisions contained in §2.5(a)(ii); provided that no Eurodollar Rate Loan may be continued as such when any Default or Event of
Default has occurred and is continuing but shall be automatically converted to a Prime Rate Loan on the last day of the first Interest Period relating thereto ending during the continuance of any Default or Event of Default. The Borrower shall
notify the Agent promptly when any such automatic conversion contemplated by this §2.5(b) is scheduled to occur. 
 (c)
Subject to the provisions of §2.5(a), §2.5(b) and §2.5(d), in the event that the Borrower does not notify the Agent of its election hereunder with respect to any Revolving Credit Loan, such Loan shall be automatically converted to (or
continued as) a Eurodollar Rate Loan having a 1-month Interest Period, at the end of the applicable Interest Period; provided, if such Revolving Credit Loan is a Prime Rate Loan made at a point when the time between the end of the initial Interest
Period for such Prime Rate Loan and the making of such Prime Rate Loan is less than three (3) Eurodollar Business Days, such Prime Rate Loan shall continue as a Prime Rate Loan and not be so converted to a Eurodollar Rate Loan until the end of
the Interest Period for such Prime Rate Loan which next follows such Prime Rate Loan’s initial Interest Period; and provided further, however, that nothing contained in the foregoing proviso shall limit or restrict Borrower’s right to
convert such Prime Rate Loan to a Eurodollar Rate Loan prior to the end of such second Interest Period in accordance with §2.5(a)(ii). 
 (d) The Borrower may not request or elect a Eurodollar Rate Loan pursuant to §2.4, elect to convert a Prime Rate Loan to a Eurodollar Loan pursuant to §2.5(a) or elect to continue a Eurodollar Rate Loan
pursuant to §2.5(b) and a Revolving Credit Loan shall not be automatically converted to or continued as a Eurodollar Rate Loan, if, after giving effect thereto, there would be greater than six (6) Eurodollar Rate Loans then outstanding.
Any Loan Request or Conversion Request for a Eurodollar Rate Loan that would create greater than six (6) Eurodollar Rate Loans outstanding shall be deemed to be a Loan Request or Conversion Request for a Prime Rate Loan. By way of explanation
of the foregoing, in the event that the Borrower wishes to convert or continue 

  

 -32- 








 
two or more Loans into one Eurodollar Rate Loan on the same day and for identical Interest Periods (or borrow an additional Revolving Credit Loan
simultaneously with converting or continuing a Revolving Credit Loan for identical Interest Periods), such Eurodollar Rate Loan shall constitute one single Eurodollar Rate Loan for purposes of this clause (d). 
 §2.6. Funds for Revolving Credit Loans. 
 (a) Subject to the other provisions of this §2, not later than 11:00 a.m. (Boston time) on the proposed Drawdown Date of any Revolving Credit Loan, each of the Banks will make available to the Agent, at
Agent’s Funding Office, in immediately available funds, the amount of such Bank’s Commitment Percentage of the amount of the requested Revolving Credit Loan. Upon receipt from each Bank of such amount, the Agent will make available to the
Borrower the aggregate amount of such Revolving Credit Loan made available to the Agent by the Banks. All such funds received by the Agent by 11:00 a.m. (Boston Time) on any Business Day will be made available to the Borrower not later than 2:00
p.m. on the same Business Day; funds received after such time will be made available by not later than 11:00 a.m. on the next Business Day (provided that as to any Bank which is required to fund Revolving Credit Loans from its head office located in
the Pacific Time Zone (U.S.), the preceding reference to ‘11:00 a.m.’ shall be deemed to be a reference to ‘1:00 p.m.’). The failure or refusal of any Bank to make available to the Agent at the aforesaid time and place on any
Drawdown Date the amount of its Commitment Percentage of the requested Revolving Credit Loan shall not relieve any other Bank from its several obligation hereunder to make available to the Agent the amount of its Commitment Percentage of any
requested Revolving Credit Loan but in no event shall the Agent (in its capacity as Agent) have any obligation to make any funding or shall any Bank be obligated to fund more than its Commitment Percentage of the requested Revolving Credit Loan or
to increase its Commitment Percentage on account of such failure or otherwise. 
 (b) The Agent may, unless notified to the
contrary by any Bank prior to a Drawdown Date, assume that such Bank has made available to the Agent on such Drawdown Date the amount of such Bank’s Commitment Percentage of the Revolving Credit Loan to be made on such Drawdown Date, and the
Agent may (but it shall not be required to), in reliance upon such assumption, make available to the Borrower a corresponding amount. If any Bank makes available to the Agent such amount on a date after such Drawdown Date, such Bank shall pay to the
Agent on demand an amount equal to the product of (i) the average, computed for the period referred to in clause (iii) below, of the weighted average interest rate paid by the Agent for federal funds acquired by the Agent during each day
included in such period, multiplied by (ii) the amount of such Bank’s Commitment Percentage of such Revolving Credit Loan, multiplied by (iii) a fraction, the numerator of which is the number of days that elapsed from
and including such Drawdown Date to the date on which the amount of such Bank’s Commitment Percentage of such Revolving Credit Loan shall become immediately available to the Agent, and the denominator of which is 365. A statement of the Agent
submitted to such 

  

 -33- 








 
Bank with respect to any amounts owing under this paragraph shall be prima facie evidence of the amount due and owing to the Agent by such
Bank. 
 §2.7. Reduction of Commitment. The Borrower shall have the right at any time and from time to time upon five
(5) Business Days’ prior written notice to the Agent to reduce by $500,000 or an integral multiple thereof or terminate entirely the unborrowed portion of the then Total Commitment, whereupon the Commitments of the Banks shall be reduced
pro rata in accordance with their respective Commitment Percentages by the amount specified in such notice or, as the case may be, terminated. Upon the effective date of any such reduction or termination, the Borrower shall pay to the
Agent for the respective accounts of the Banks the full amount of the Facility Fee then accrued and unpaid on the amount of the reduction. No reduction or termination of the Commitments may be reinstated. In the event the aggregate Commitments of
the Banks have been reduced to zero ($0), no Letters of Credit are then issued and outstanding hereunder, and the Loans and all other Obligations outstanding or due hereunder have been paid or repaid in full in cash, this Agreement and the revolving
credit facility shall automatically terminate (except as to those provisions hereof which expressly survive such termination), unless otherwise agreed to in writing by the Agent and the Borrower. Agent shall promptly provide each Bank with copies of
any notices received by Agent from Borrower under this §2.7. 
 §2.8. Swingline Loans. 
 (a) Availability. Subject to the terms and conditions of this Agreement and so long as the Swingline Lender does not have knowledge
that any Default or Event of Default exists or will exist after giving effect to the applicable Swingline Loan, and the Borrower has delivered to the Agent a loan request in the form of Exhibit B hereto, the Swingline Lender agrees to make
Swingline Loans to the Borrower from time to time from the Closing Date to, but not including, the Swingline Termination Date; provided, that the aggregate principal amount of all outstanding Swingline Loans (after giving effect to any amount
requested) at any time, shall not exceed the lesser of (i) the Total Commitment in effect at such time less the sum of (A) all outstanding Revolving Credit Loans at such time (after giving effect to all amounts requested),
(B) the Maximum Drawing Amount and, without double-counting the portion, if any, of any Letter of Credit which is drawn and included in the Revolving Credit Loans or the Maximum Drawing Amount, all outstanding Reimbursement Obligations at such
time, and (C) all outstanding Bid Rate Loans at such time, and (ii) the Swingline Commitment at such time. Swingline Loans hereunder may be used in anticipation of borrowing Revolving Credit Loans, Bid Rate Loans and for other short-term
requirements and shall be repaid in accordance with the terms hereof. Each Swingline Loan must be for an amount equal to at least $1,000,000 and in an integral multiple of $100,000 and shall be evidenced by the Swingline Note. The Swingline Lender
shall initiate the transfer of funds representing the Swingline Loan to the Borrower by 4:00 p.m. (Boston time) on the Business Day of the requested borrowing, so long as the Swingline Loan has been requested by the Borrower no later than 1:00 p.m.
(Boston time) on such Business Day. In no event shall the number of Swingline Loans 

  

 -34- 








 
outstanding at any time exceed three (3). All Swingline Loans shall bear interest at the Prime Rate plus the Applicable Prime Rate Margin. The Borrower
unconditionally promises to pay interest on each Swingline Loan in arrears on each Interest Payment Date with respect thereto. 
 (b) Repayment. The Borrower hereby absolutely and unconditionally promises to repay the outstanding principal amount of each Swingline Loan and all accrued interest and charges thereon (the “Swingline Loan Amount”) on the
earliest to occur of: (i) the fifth (5th) Business Day after the date on which the Swingline Loan is
advanced or (ii) the Swingline Termination Date; provided, the Borrower shall have the right to prepay Swingline Loans without penalty or any prepayment charge. 
 (c) Refunding and Conversion of Swingline Loans to Revolving Credit Loans. 
 (i) On the maturity of each Swingline Loan (which shall be no longer than the period for repayment set forth above in §2.8(b)), the
Borrower shall be deemed to have requested on such date a Revolving Credit Loan comprised solely of a Prime Rate Loan in a principal amount equal to the Swingline Loan Amount in order to repay such Swingline Loan. Such refundings of the Swingline
Loan through the funding of such Revolving Credit Loans shall be made by the Banks in accordance with their respective Commitment Percentages and shall thereafter be reflected as Revolving Credit Loans of the Banks on the books and records of the
Agent. 
 (ii) If a Default or an Event of Default has occurred and is continuing, all Swingline Loans shall be refunded by
the Banks on demand by the Swingline Lender, in which case the Borrower shall be deemed to have requested on such date of demand a Revolving Credit Loan comprised solely of a Prime Rate Loan in a principal amount equal to the Swingline Loan Amount
for such Swingline Loans. Such refundings of the Swingline Loans through the funding of such Revolving Credit Loans shall be made by the Banks in accordance with their respective Commitment Percentages and shall thereafter be reflected as Revolving
Credit Loans of the Banks on the books and records of the Agent. 
 (iii) Each Bank shall fund its respective Commitment
Percentage of Revolving Credit Loans as required to so repay Swingline Loans outstanding to the Swingline Lender upon such deemed request or demand by the Swingline Lender but in no event later than 2:00 p.m. (Boston time) on the next succeeding
Business Day after such deemed request or demand is made. No Bank’s obligation to fund its respective Commitment Percentage of the repayment of a Swingline Loan shall be affected by any other Bank’s failure to fund its Commitment
Percentage of such repayment, nor shall any Bank’s Commitment Percentage be increased as a result of any such failure of any other Bank to fund its Commitment Percentage. To the extent any Bank does not fund its respective Commitment Percentage
of any Revolving Credit Loan to the Borrower pursuant to this §2.8(c)(iii), such Bank shall be deemed a Delinquent Bank and the Borrower shall repay such amounts to the Swingline Lender in accordance 

  

 -35- 








 
with the provisions of §4.3 as if such Loan were a Revolving Credit Loan for which a Bank did not remit its share to the Agent. If any portion of any
such amount paid to the Swingline Lender shall be recovered by or on behalf of the Borrower from the Swingline Lender in bankruptcy or otherwise, the loss of the amount so recovered shall be ratably shared among all the Banks. 
 (iv) If at any time the Borrower receives notice from the Swingline Lender that the aggregate principal amount of all Revolving Credit
Loans outstanding, plus the aggregate principal amount of all Swingline Loans outstanding (including the Swingline Loan for which demand for payment is then made by the Swingline Lender pursuant to this subsection), plus the Maximum
Drawing Amount and, plus, without double-counting the portion, if any, of any Letter of Credit which is drawn and included in the Revolving Credit Loans or the Maximum Drawing Amount, all outstanding Reimbursement Obligations at such time,
plus all outstanding Bid Rate Loans at such time, equals or exceeds the Total Commitment at such time the Borrower shall repay the amount of such excess upon demand by the Swingline Lender, which payment shall be applied first to the
Swingline Loans, second to the Revolving Credit Loans and thereafter to the Bid Rate Loans. 
 (v) Each Bank acknowledges and
agrees that its obligation to refund Swingline Loans with Revolving Credit Loans in accordance with the terms of this §2.8 is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, in any event,
non-satisfaction of any conditions set forth in this Agreement pertaining to advances of Revolving Credit Loans hereunder, except to the limited extent expressly referred to in the first sentence of §2.8(a). Further, each Bank agrees and
acknowledges that if, prior to the refunding of any outstanding Swingline Loans pursuant to this §2.8, one of the events described in §§14.1(g) or (h) shall have occurred, each Bank will, on the date the applicable Revolving
Credit Loan would have been made pursuant to §2.8(c)(i) or (ii), purchase an undivided participating interest in the Swingline Loan to be refunded in an amount equal to its Commitment Percentage of such Swingline Loan Amount. Each Bank will
immediately transfer to the Swingline Lender, in immediately available funds, the amount of its participation. Whenever, at any time after the Swingline Lender has received from any Bank such Bank’s participating interest in a Swingline Loan,
the Swingline Lender receives any payment on account thereof, the Swingline Lender will distribute to such Bank its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during
which such Bank’s participating interest was outstanding and funded). 
 (vi) Each Bank’s Commitment Percentage
applicable to any Swingline Loan shall be identical to its Commitment Percentage applicable to Revolving Credit Loans. 
  

 -36- 








 §2.9. Bid Rate Advances. 
 (a) Each Bank severally agrees that, on the terms and conditions set forth in this Agreement, the Borrower may request and receive Bid
Rate Advances under this §2.9 from time to time on any Business Day during the period from the date hereof until the date occurring 30 days prior to the Maturity Date in the manner set forth below; provided, however, that:

 (i) following the making of each Bid Rate Advance, the aggregate principal amount of all Revolving Credit Loans then
outstanding, plus the aggregate amount of all Swingline Loans then outstanding, plus the aggregate amount of all Bid Rate Advances then outstanding (including the requested Bid Rate Advance), plus the Maximum Drawing Amount and,
without double-counting the portion, if any, of any Letter of Credit which is drawn and included in the Revolving Credit Loans or the Maximum Drawing Amount, plus all outstanding Reimbursement Obligations at such time, shall not exceed the
Total Commitment in effect at such time; 
 (ii) at no time shall the aggregate amount of all Bid Rate Advances then
outstanding (including the requested Bid Rate Advance) exceed the Bid Rate Maximum Amount; and 
 (iii) at the time the
Borrower requests a Bid Rate Advance and after giving effect to the making thereof, no Default or Event of Default has occurred and is continuing. 
 (b) The procedures for the solicitation and acceptance of Bid Rate Loans are set forth below (with the references to time of day meaning Boston, Massachusetts time): 
 (i) The Borrower may request a Bid Rate Advance under this §2.9(b) by giving the Agent irrevocable notice, in the form attached
hereto as Exhibit D-2 (a “Bid Rate Advance Borrowing Notice”), specifying the date and aggregate amount of the proposed Bid Rate Advance, the maturity date for repayment of each Bid Rate Loan to be made as part of such Bid Rate Advance
(which maturity date may not be earlier than, in the case of an Absolute Rate Auction, the date occurring one day, and in the case of an Indexed Rate Auction, the date occurring seven days, after the date of the related Bid Rate Advance or later
than, in either case, the earlier of the day occurring 180 days after the date of such Bid Rate Advance and the Maturity Date), and any other terms to be applicable to such Bid Rate Advance, not later than 11:00 a.m. (A) in the case of an
Absolute Rate Auction, one (1) Business Day prior to the date of the proposed Bid Rate Advance, and (B) in the case of an Indexed Rate Auction, four (4) Business Days prior to the date of the proposed Bid Rate Advance. Each Bid Rate
Advance Borrowing Notice shall also include a certification by Borrower in the form set forth in Exhibit D-2 which 

  

 -37- 








 
certifies (among other things) that, both before and after giving effect to such requested Bid Rate Advance, each of the conditions to borrowing set forth in
§13 have been satisfied, including, without limitation, in §13.1. The Agent shall, promptly following its receipt of a Bid Rate Advance Borrowing Notice under this §2.9(b), notify each Bank of such request by sending such Bank a copy
of such Bid Rate Advance Borrowing Notice. 
 (ii) Each Bank may, if, in its sole discretion, it elects to do so, irrevocably
offer to make one or more Bid Rate Loans to the Borrower as part of such proposed Bid Rate Advance at a rate or rates of interest specified by such Bank in its sole discretion, by providing written notice to the Agent (which shall give prompt notice
thereof to the Borrower), before 10:30 a.m. (or if such Bank is serving as the Agent, before 10:00 a.m.) on (A) the date of such proposed Bid Rate Advance, in the case of an Absolute Rate Auction, and (B) the date that is three Business
Days before the date of such proposed Bid Rate Advance, in the case of an Indexed Rate Auction, in the form of Exhibit D-3 attached hereto (the “Competitive Bid Notice”) of the minimum amount and maximum amount of each Bid Rate Loan which
such Bank would be willing to make as part of such proposed Bid Rate Advance (which amounts may, subject to the proviso to the first sentence of §2.9(a), exceed such Bank’s Commitment) and the rate or rates of interest therefor.

 Any Competitive Bid Notice shall be disregarded and given no effect if it contains qualifying or conditional language,
proposes terms and conditions other than or in addition to those set forth in the applicable Bid Rate Advance Borrowing Notice or arrives after the time set forth above for its receipt by the Agent. 
 (iii) The Borrower shall, in turn, before (A) 1:00 p.m. on the date of such proposed Bid Rate Advance, in the case of an Absolute
Rate Auction, and (B) 1:00 p.m. three Business Days before the date of such proposed Bid Rate Advance, in the case of an Indexed Rate Auction, either: 
 (x) cancel such Bid Rate Advance by giving the Agent notice to that effect, or 
 (y) accept one or more of the offers made by any Bank or Banks pursuant to §2.9(b), in its sole discretion and subject to
§2.9(d), by giving notice, in the form of Exhibit D-4 attached hereto, to the Agent of the amount of each Bid Rate Loan to be made by each Bank as part of such Bid Rate Advance, and reject any remaining offers made by Banks pursuant to
§2.9(b)(ii) by giving the Agent notice to that effect. 
  

 -38- 








 (iv) If the Borrower notifies the Agent that such Bid Rate Advance is canceled pursuant
to §2.9(b)(iii)(x), the Agent shall give prompt notice thereof to the Banks and such Bid Rate Advance shall not be made. 
 (v) If the Borrower accepts one or more of the offers made by any Bank or Banks pursuant to §2.9(b)(iii)(y), the Agent shall in turn promptly notify (A) each Bank that has made an offer as described in §2.9(b)(ii) of the
date, and aggregate amount of such Bid Rate Advance and whether or not any offer or offers made by such Bank pursuant to §2.9(b)(ii) have been accepted by the Borrower and (B) each Bank that is to make a Bid Rate Loan as part of such Bid
Rate Advance, of the amount of each Bid Rate Loan to be made by such Bank as part of such Bid Rate Advance. Each Bank that is to make a Bid Rate Loan as part of such Bid Rate Advance shall, not later than the specified remittance time (as set forth
in the notice received from the Agent pursuant to clause (B) of the preceding sentence) on the date of such Bid Rate Advance specified in the notice received from the Agent pursuant to clause (B) of the preceding sentence, make available
to the Agent such Bank’s portion of such Bid Rate Advance, in same day funds. After receipt by the Agent of such funds and provided that the conditions in §13 are satisfied and the Borrower has delivered to the Agent the certificate
referred to in §2.4(iv)(c) as if all references in §2.4(iv)(c) to Revolving Credit Loans were to Bid Rate Loans, the Agent will make such funds available to the Borrower upon execution and delivery to the applicable Bank (with a copy to
the Agent) by the Borrower of a Bid Rate Note evidencing such Bid Rate Loan (and the provisions set forth in the last two sentences of §2.2 relating to Revolving Credit Notes shall apply equally to the Bid Rate Notes). Promptly after each Bid
Rate Advance the Agent will notify each Bank of such Bid Rate Advance. 
 (vi) If the Borrower accepts one or more of the
offers made by any Bank or Banks pursuant to §2.9(b)(iii)(y) and fails to borrow any Bid Rate Loan so accepted, the Borrower shall indemnify the Bank funding such Loan against any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Bank to fund or maintain such unborrowed Bid Rate Loans, including, without limitation, Eurodollar Breakage Costs and other compensation, if any, as provided in §5.8. 
 (vii) A Bid Rate Advance fee of $750.00 shall be payable by the Borrower to the Agent, for the account of the Agent, with respect to and
concurrently with the delivery of each Bid Rate Advance Borrowing Notice. 
  

 -39- 








 (c) Each Bid Rate Advance shall be in an aggregate amount not less than $5,000,000 or an
integral multiple of $1,000,000 in excess thereof, and, following the making of each Bid Rate Advance, the Borrower shall be in compliance with the limitation set forth in the proviso to §2.9(a). 
 (d) Each acceptance by the Borrower pursuant to §2.9(b)(iii)(y) of the offers made in response to a Bid Rate Advance Borrowing Notice
shall be treated as an acceptance of such offers in ascending order of the rates or margins, as applicable, at which the same were made but if, as a result thereof, two or more offers at the same such rate or margin would be partially accepted, then
the amounts of the Bid Rate Loans in respect of which such offers are accepted shall be treated as being the amounts which bear the same proportion to one another as the respective amounts of the Bid Rate Loans so offered bear to one another but, in
each case, rounded as the Agent may consider necessary to ensure that the amount of each such Bid Rate Loan is $5,000,000 or an integral multiple of $1,000,000 in excess thereof. 
 (e) Within the limits and on the conditions set forth in this §2.9, the Borrower may from time to time borrow under this §2.9,
repay pursuant to §2.9(f), and reborrow under this §2.9. 
 (f) The Borrower hereby absolutely and unconditionally
promises to pay to the Agent for the account of each Bank which has made a Bid Rate Loan to it, on the maturity date of such Bid Rate Loan (such maturity date being that specified by the Borrower for repayment of such Bid Rate Loan in the related
Bid Rate Advance Borrowing Notice) or such earlier date to which the maturity of such Bid Rate Loan has been accelerated hereunder, the then unpaid principal amount of such Bid Rate Loan and all accrued but unpaid interest thereon. The Borrower
shall have no right to prepay any principal amount of any Bid Rate Loan unless, and then only on the terms, specified by the Borrower for such Bid Rate Loan in the related Bid Rate Advance Borrowing Notice and subject to payment of Eurodollar
Breakage Costs and other compensation, if any, as provided in §5.8. 
 (g) The Borrower shall, and hereby absolutely and
unconditionally promises to, pay interest on the unpaid principal amount of each Bid Rate Loan made to it, from the date of such Bid Rate Loan to the date the principal amount of such Bid Rate Loan is repaid in full, at the rate of interest for such
Bid Rate Loan specified by the Bank making such Bid Rate Loan in the related notice submitted by such Bank pursuant to §2.9(b)(ii), payable on the interest payment date or dates specified by the Borrower for such Bid Rate Loan in the related
Bid Rate Advance Borrowing Notice and on any date on which such Bid Rate Loan is prepaid, whether by acceleration or otherwise, and at maturity. In the event the term of any Bid Rate Loan shall be longer than three months, interest thereon shall be
payable not less frequently than once each three-month period during such term. Interest on Bid Rate Loans shall be calculated for actual days elapsed on the basis of a 360-day year. 
  

 -40- 








 (h) Each Existing Bid Rate Advance, upon the effectiveness of this Agreement, shall
automatically be deemed to be a Bid Rate Advance made under and pursuant to this Agreement for all purposes. 
 §2.10. Increases in
Total Commitment. The Borrower shall have the right to cause the Total Commitment to increase in minimum increments of $50,000,000 up to an aggregate increase amount not at any time exceeding $395,000,000 (the “Increase”), in which
event the Agent will amend Schedule 2 to reflect the increased Commitment of each Bank, if any, that has agreed in writing to an increase and to add any third party financial institution that may have become a party to, and a “Bank”
under, this Agreement in connection with the Increase; provided, however, that it shall be a condition precedent to the effectiveness of the Increase that the Increase Conditions shall have been satisfied and provided further the last
minimum increment to bring the aggregate Increase up to $395,000,000 shall be $45,000,000 rather than $50,000,000. In the event that the Increase results in any change to the Commitment Percentage of any Bank, then on the effective date of such
Increase in the Total Commitment (i) any new Bank, and any existing Bank whose Commitment has increased, shall pay to the Agent such amounts as are necessary to fund its new or increased Commitment Percentage of all existing Revolving Credit
Loans, (ii) the Agent will use the proceeds thereof to pay to all Banks whose Commitment Percentage is decreasing such amounts as are necessary so that each such Bank’s participation in existing Revolving Credit Loans will be equal to its
adjusted Commitment Percentage, and (iii) if the effective date of such Increase in the Total Commitment occurs on a date other than the last day of an Interest Period applicable to any outstanding Eurodollar Rate Loan, the Borrower will be
responsible for Eurodollar Breakage Costs and any other amounts payable pursuant to §5.8 on account of the payments made pursuant to clause (ii) above. In no event shall any Bank be required to participate in an Increase. 
 §2.11. Extension of Revolving Credit Maturity Date. At least 30 days but in no event more than 90 days prior to August 3, 2010, the
Borrower, by written notice to the Agent (with copies for each Bank), may request an extension of the Maturity Date by a period of one year from the Maturity Date then in effect (the “Extension”). The Extension shall become effective on
August 3, 2010 so long as (i) the Borrower has paid to the Agent on such date, for the ratable accounts of the Banks, an extension fee in an amount equal to 15 basis points on the Total Commitment in effect on such date (“Extension
Fee”), and (ii) no Default or Event of Default has occurred and is continuing on such date and all representations and warranties contained in the Loan Documents shall be true and correct as of such date (except (i) to the extent of
changes resulting from transactions contemplated or not prohibited by this Agreement or the other Loan Documents and changes occurring in the ordinary course of business, (ii) to the extent that such representations and warranties relate
expressly to an earlier date and (iii) to the extent otherwise represented by the Borrower with respect to the representation set forth in §7.10). The notice referred to in the first sentence of this §2.11 shall constitute and shall
be deemed to be a certification by the Borrower as to the truth and accuracy of the statements contained in clause (ii) of the preceding sentence.

 §3. LETTERS OF CREDIT. 
 §3.1. Letter of Credit Commitments. 
 §3.1.1. Commitment to Issue Letters of Credit. Subject to the terms and conditions hereof and the execution and delivery by the Borrower of a letter of credit application on the Fronting Bank’s
customary form as part of a Completed Loan Request (a “Letter of Credit Application”), the Fronting Bank on behalf of the Banks and in reliance upon the agreement of the Banks set forth in §3.1.4 and upon the representations and
warranties of the Borrower contained herein, agrees, in its individual capacity, to issue, extend and renew for the account of the Borrower (or, so long as Borrower remains fully liable on the applicable Letter of Credit Application, for the account
of a Wholly-Owned Subsidiary of Borrower or a Partially-Owned Entity) one or more letters of credit (individually, a “Letter of Credit”), in such form as may be requested from time to time by the Borrower and reasonably agreed to by the
Fronting Bank; provided, however, that, after giving effect to such Completed Loan Request, (a) the Maximum Drawing Amount plus all Reimbursement Obligations (to the extent, if any, not yet deemed a Revolving Credit Loan pursuant
to §3.3), shall not exceed $200,000,000 at any one time and (b) the sum of (i) the Maximum Drawing Amount and, without double counting, all Reimbursement Obligations (to the extent, if any, not yet deemed a Revolving Credit Loan
pursuant to §3.3) and (ii) the amount of all Loans (including Swingline Loans and Bid Rate Loans) outstanding shall not exceed the Total Commitment in effect at such time. It is acknowledged that the Existing Letters of Credit are to be
treated as Letters of Credit hereunder for all purposes, including, without limitation, with respect to the Reimbursement Obligations of the Borrower under §3.2 and the funding obligations of the Banks under §3.3. As this Agreement
constitutes an entire amendment and restatement of the Existing Credit Agreement, it is acknowledged and agreed that BOA shall not, and shall not have any obligation to, issue any further Letters of Credit under the Existing Credit Agreement.

 §3.1.2. Letter of Credit Applications. Each Letter of Credit Application shall be completed to the reasonable
satisfaction of the Agent and the Fronting Bank. In the event that any provision of any Letter of Credit Application shall be inconsistent with any provision of this Agreement (including provisions applicable to a Completed Loan Request) or shall
impose additional financial or other material obligations (other than technical, administrative and ministerial obligations, whether relating to the mechanics of a draw under a Letter of Credit or otherwise), then the provisions of this Agreement
shall, to the extent of any such inconsistency or additional material obligation, govern. 
 §3.1.3. Terms of Letters
of Credit. Each Letter of Credit issued, extended or renewed hereunder shall, among other things, (i) provide for the payment of sight drafts for honor thereunder when presented in accordance with the terms thereof and when accompanied by
the documents described therein, and (ii) have an expiry date no later than the date which is fourteen (14) days prior to the Maturity Date. Each Letter of Credit so issued, extended or renewed shall be subject to the Uniform Customs.

  

 -42- 








 §3.1.4. Obligations of Banks with respect to Letters of Credit. Each Bank
severally agrees that it shall be absolutely liable, without regard to the occurrence of any Default or Event of Default or any other condition precedent whatsoever, to the extent of such Bank’s Commitment Percentage, to reimburse the Fronting
Bank on demand pursuant to §3.3 for the amount of each draft paid by the Fronting Bank under each Letter of Credit to the extent that such amount is not reimbursed by the Borrower pursuant to §3.2 (such agreement for a Bank being called
herein the “Letter of Credit Participation” of such Bank). Each such payment made by a Bank shall be treated as a purchase by such Bank of a participation in the Fronting Bank’s interest in such Letter of Credit and each Bank shall
share, in accordance with its respective Commitment Percentage, in any interest which accrues and is payable by the Borrower pursuant to §3.2 or otherwise in connection with such Letter of Credit. 
 §3.1.5. Fronting Bank. Notwithstanding the definition of Fronting Bank, in the event that the Borrower reasonably determines
that it would be beneficial to have a Letter of Credit issued by a Bank with a higher rating than BOA has at any applicable time of reference (as determined by Moody’s or S&P), or for any other reason acceptable to the Agent, the Borrower
shall have the right to elect any Bank having a higher rating than BOA (or such other applicable Bank) as the Fronting Bank for that particular Letter of Credit, provided that no Bank other than BOA shall be required to be a Fronting Bank.

 §3.2. Reimbursement Obligation of the Borrower. In order to induce the Fronting Bank to issue, extend and renew each Letter of
Credit and the Banks to participate therein, the Borrower hereby agrees, except as contemplated in §3.3, to reimburse or pay to the Fronting Bank, for the account of the Fronting Bank or (as the case may be) the Banks, with respect to each
Letter of Credit issued, extended or renewed by the Fronting Bank hereunder, 
 (a) except as otherwise expressly provided in
§3.2(b) and (c) or §3.3, promptly upon notification by the Fronting Bank or the Agent that any draft presented under such Letter of Credit is honored by the Fronting Bank, or the Fronting Bank otherwise makes a payment with respect
thereto, (i) the amount paid by the Fronting Bank under or with respect to such Letter of Credit, and (ii) any amounts payable pursuant to §5.5 under, or with respect to, such Letter of Credit, 
 (b) upon the reduction (but not termination) of the Total Commitment to an amount less than the then Maximum Drawing Amount (after taking
into account all outstanding Loans and Reimbursement Obligations, if any (without double counting)), an amount equal to such difference, which amount shall be held by the Agent in an interest-bearing account (with interest to be added to such
account) as cash collateral for the benefit of the Banks and the Agent for all Reimbursement Obligations, and 
 (c) upon the
termination of the Total Commitment, or the acceleration of the Reimbursement Obligations with respect to all Letters of Credit in accordance with §14, an amount equal to the then Maximum Drawing Amount on all Letters of Credit, which amount
shall be held by the Agent in an interest-bearing account (with interest to 

  

 -43- 








 
be added to such account) as cash collateral for the benefit of the Banks and the Agent for all Reimbursement Obligations. 
 Each such payment shall be made to the Agent for the benefit of the Banks at the Agent’s Funding Office in immediately available funds. Interest on
any and all amounts not converted to a Revolving Credit Loan pursuant to §3.3 and remaining unpaid by the Borrower under this §3.2 at any time from the date such amounts become due and payable (whether as stated in this §3.2, by
acceleration or otherwise) until payment in full (whether before or after judgment) shall be payable to the Agent for the benefit of the Banks on demand at the rate specified in §5.9 for overdue principal on the Loans. 
 §3.3. Letter of Credit Payments; Funding of a Loan. If any draft shall be presented or other demand for payment shall be made under any
Letter of Credit, the Fronting Bank will use its best efforts to notify the Borrower and the Agent (who will use its best efforts to promptly notify each of the Banks), on or before the date the Fronting Bank intends to honor such drawing, of the
date and amount of the draft presented or demand for payment and of the date and time when it expects to pay such draft or honor such demand for payment and, except to the extent the amount of such draft becomes a Revolving Credit Loan as set forth
in this §3.3, Borrower shall reimburse Agent, as set forth in §3.2. Notwithstanding anything contained in §3.2 or this §3.3 to the contrary, however, unless Borrower shall have notified the Agent and Fronting Bank prior to 11:00
a.m. (New York time) on the Business Day immediately prior to the date of such drawing that Borrower intends to reimburse Fronting Bank for the amount of such drawing with funds other than the proceeds of Revolving Credit Loans, Borrower shall be
deemed to have timely given a Completed Loan Request pursuant to §2.4 to Agent, requesting a Prime Rate Loan on the date on which such drawing is honored and in an amount equal to the amount of such drawing. The Borrower may thereafter convert
any such Prime Rate Loan to a Revolving Credit Loan of another Type in accordance with §2.5. Each Bank shall, in accordance with §2.6, make available such Bank’s Commitment Percentage of such Revolving Credit Loan to Agent, the
proceeds of which shall be applied directly by Agent to reimburse Fronting Bank for the amount of such draw. In the event that any Bank fails to make available to Agent the amount of such Bank’s Commitment Percentage of such Revolving Credit
Loan on the date of any drawing, Agent shall be entitled to recover such amount on demand from such Bank plus any additional amounts payable under §2.6(b) in the event of a late funding by a Bank. The Fronting Bank is irrevocably authorized by
the Borrower and each of the Banks to honor draws on each Letter of Credit by the beneficiary thereof in accordance with the terms of such Letter of Credit. The responsibility of the Agent to the Borrower and the Banks shall be only to determine
that the documents (including each draft) delivered under each Letter of Credit in connection with such presentment shall be in conformity in all material respects with such Letter of Credit. 
 §3.4. Obligations Absolute. The Borrower’s obligations under this §3 shall be absolute and unconditional under any and all
circumstances and irrespective of the account party in whose name a Letter of Credit is issued pursuant to a Letter of Credit Application executed by Borrower or the occurrence of any Default or Event of Default 

  

 -44- 








 
or any condition precedent whatsoever or any setoff, counterclaim or defense to payment which the Borrower may have or have had against the Agent, any Bank
or any beneficiary of a Letter of Credit. The Borrower further agrees with the Agent and the Banks that the Agent and the Banks shall not be responsible for, and the Borrower’s Reimbursement Obligations under §3.2 shall not be affected by,
among other things, the validity or genuineness of documents or of any endorsements thereon (so long as the documents delivered under each Letter of Credit in connection with such presentment shall be in the form required by, and in conformity in
all material respects with, such Letter of Credit), even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, the beneficiary of any Letter of Credit or any
financing institution or other party to whom any Letter of Credit may be transferred, or any claims or defenses whatsoever of the Borrower against the beneficiary of any Letter of Credit or any such transferee. The Agent and the Banks shall not be
liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit. The Borrower agrees that any action taken or omitted by the Agent or
any Bank under or in connection with each Letter of Credit and the related drafts and documents, if done in good faith and absent gross negligence, shall be binding upon the Borrower and shall not result in any liability on the part of the Agent or
any Bank to the Borrower. 
 §3.5. Reliance by Issuer. To the extent not inconsistent with §3.4, the Agent and any Fronting
Bank shall be entitled to rely, and shall be fully protected in relying upon, any Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement,
order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel, independent accountants and other experts selected by the Agent.
The Agent and any Fronting Bank shall be fully justified in failing or refusing to take any action under this §3 (other than the issuance of a Letter of Credit pursuant to a Letter of Credit Application and otherwise in accordance with the
terms of this Agreement) unless it shall first have received such advice or concurrence of the Required Banks (or such other number or percentage of the Banks as may be required by this Agreement) as it reasonably deems appropriate or it shall first
be indemnified to its reasonable satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Agent and any Fronting Bank shall in all cases be fully
protected by the Banks in acting, or in refraining from acting, under this §3 in accordance with a request of the Required Banks (or such other number or percentage of the Banks as may be required by this Agreement), and such request and any
action taken or failure to act pursuant thereto shall be binding upon the Banks and all future holders of the Notes or of a Letter of Credit Participation. 
 §3.6. Letter of Credit Fee. The Borrower shall pay to the Agent a fee (in each case, a “Letter of Credit Fee”) in an amount equal to the Applicable L/C Percentage of the undrawn amount of each
outstanding Letter of Credit (as calculated with respect to each Letter of Credit’s Maximum Drawing Amount), which fee (a) shall be payable 

  

 -45- 








 
quarterly in arrears on the first day of each calendar quarter for the immediately preceding calendar quarter, with a final payment on the Maturity Date or
any earlier date on which the Commitments shall terminate (which Letter of Credit Fee shall be pro-rated for any calendar quarter in which such Letter of Credit is issued, drawn upon or otherwise reduced or terminated) and (b) shall be for the
accounts of the Banks as follows: (i) an amount equal to 0.125% per annum of the Letter of Credit Fee shall be for the account of the Fronting Bank and (ii) the remainder of the Letter of Credit Fee shall be for the accounts of the
Banks (including the Fronting Bank as a Bank) pro rata in accordance with their respective Commitment Percentages. In addition, Borrower shall pay to the Fronting Bank, for its own account, an amount equal to the Fronting Bank’s
reasonable and customary costs and expenses incurred in connection with the issuance and/or administration of the Letters of Credit. 
 §4. REPAYMENT OF THE LOANS. 
 §4.1. Maturity. In addition to, and without limiting, the provisions of
§2.8(b) and §2.9(f), the Borrower promises to pay on the Maturity Date, and there shall become absolutely due and payable on the Maturity Date, all unpaid principal of the Revolving Credit Loans and each other Loan, if any, outstanding on
such date, together with any and all accrued and unpaid interest thereon, the unpaid balance of the Facility Fee accrued through such date, and any and all other unpaid amounts due under this Agreement, the Notes or any other of the Loan Documents.

 §4.2. Optional Repayments of Revolving Credit Loans. The Borrower shall have the right, at its election, to prepay the
outstanding amount of the Revolving Credit Loans, in whole or in part, at any time without penalty or premium; provided that the outstanding amount of any Eurodollar Rate Loans may not be prepaid unless the Borrower pays the Eurodollar
Breakage Costs for each Eurodollar Rate Loan so prepaid at the time of such prepayment. The Borrower shall give the Agent no later than 10:00 a.m., Boston, Massachusetts time, at least one (1) Business Day’s prior written notice of any
prepayment pursuant to this §4.2 of any Prime Rate Loans, and at least three (3) Eurodollar Business Days’ notice of any proposed prepayment pursuant to this §4.2 of Eurodollar Rate Loans, specifying the proposed date of
prepayment of Revolving Credit Loans and the principal amount to be prepaid. Each such partial prepayment of the Loans shall be in an amount equal to $500,000 or an integral multiple of $100,000 in excess thereof or, if less, the outstanding balance
of the Revolving Credit Loans then being repaid, shall be accompanied by the payment of all charges, if any, outstanding on all Revolving Credit Loans so prepaid and of all accrued interest on the principal prepaid to the date of payment, and shall
be applied, in the absence of instruction by the Borrower, first to the principal of Prime Rate Loans and then to the principal of Eurodollar Rate Loans. 
 §4.3 Mandatory Repayment of Loans. If at any time the sum of the outstanding amount of the Loans, plus the Maximum Drawing Amount, plus without double-counting any Revolving Credit Loans, the
outstanding Reimbursement Obligations, if any, exceeds the Total Commitment at such time, the Borrower shall, within fifteen (15) days after 

  

 -46- 








 
receiving notice of such excess from the Agent pay to the Agent an amount in cash necessary to eliminate such excess, such amount to be applied, in the
absence of instruction by the Borrower, (x) first to the repayment of Swingline Loans, second to the repayment of Revolving Credit Loans and third to the repayment of Bid Rate Loans and (y) with respect to any such payments of Revolving
Credit Loans, first to the principal of Prime Rate Loans and then to the principal of Eurodollar Rate Loans. 
 §5. CERTAIN GENERAL
PROVISIONS. 
 §5.1. Funds for Payments. 
 (a) All payments of principal, interest, fees, and any other amounts due hereunder or under any of the other Loan Documents shall be made
to the Agent, for the respective accounts of the Banks or (as the case may be) the Agent, at the Agent’s Funding Office, in each case in Dollars and in immediately available funds. The Borrower shall make each payment of principal of and
interest on the Loans and of fees hereunder and Reimbursement Obligations which are not converted to a Loan hereunder not later than 1:00 p.m. (Boston, Massachusetts time) on the due date thereof. 
 (b) All payments by the Borrower hereunder and under any of the other Loan Documents shall be made without setoff or counterclaim and free
and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory liens, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political
subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If the Borrower is compelled by law to make any such deduction or withholding with respect to any amount payable
by it hereunder or under any of the other Loan Documents (except with respect to taxes on the income or profits of the Agent or any Bank), the Borrower shall pay to the Agent, for the account of the Banks or (as the case may be) the Agent, on the
date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Banks to receive the same net amount which the Banks would have received on such due date
had no such obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder
or under such other Loan Document. 
 §5.2. Computations. All computations of interest on the Loans and of other fees to the
extent applicable shall be based on a 360-day year (365/366-day year for Prime Rate Loans) and paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term “Interest Period” with respect to
Eurodollar Rate Loans, whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall
accrue during such extension. The outstanding amount of the Loans as reflected on the Note Records or 

  

 -47- 








 
record attached to any other Note from time to time shall constitute prima facie evidence of the principal amount thereof. 
 §5.3. Inability to Determine Eurodollar Rate. In the event, prior to the commencement of any Interest Period relating to any Eurodollar Rate
Loan, the Agent shall reasonably and in good faith determine that adequate and reasonable methods do not exist for ascertaining the Eurodollar Rate that would otherwise determine the rate of interest to be applicable to any Eurodollar Rate Loan
during any Interest Period, the Agent shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower and the Banks. In such event (a) any Loan Request with respect to Eurodollar Rate
Loans shall be automatically withdrawn and shall be deemed a request for Prime Rate Loans, (b) each Eurodollar Rate Loan will automatically, on the last day of the then current Interest Period applicable thereto, become a Prime Rate Loan, and
(c) the obligations of the Banks to make Eurodollar Rate Loans shall be suspended, in each case unless and until the Agent reasonably and in good faith determines that the circumstances giving rise to such suspension no longer exist, whereupon
the Agent shall so notify the Borrower and the Banks. 
 §5.4. Illegality. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation or application thereof shall make it unlawful for any Bank to make or maintain Eurodollar Rate Loans, such Bank shall forthwith give notice of such circumstances to the
Borrower and thereupon (a) the Commitment of such Bank to make Eurodollar Rate Loans or convert Prime Rate Loans to Eurodollar Rate Loans shall forthwith be suspended and (b) such Bank’s Commitment Percentage of Eurodollar Rate Loans
then outstanding shall be converted automatically to Prime Rate Loans on the last day of each Interest Period applicable to such Eurodollar Rate Loans or within such earlier period as may be required by law, all until such time as it is no longer
unlawful for such Bank to make or maintain Eurodollar Rate Loans. Subject to the limitations set forth in §5.7, the Borrower hereby agrees promptly to pay the Agent for the account of such Bank, upon demand, any additional amounts necessary to
compensate such Bank for any costs incurred by such Bank in making any conversion required by this §5.4 prior to the last day of an Interest Period with respect to a Eurodollar Rate Loan, including any interest or fees payable by such Bank to
lenders of funds obtained by it in order to make or maintain its Eurodollar Rate Loans hereunder. 
 §5.5. Additional Costs, Etc.
If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged
with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Bank or the Agent by any central bank or other fiscal, monetary
or other authority (whether or not having the force of law, but if not having the force of law, then generally applied by the Banks or the Agent with respect to similar loans), shall: 
 (a) subject any Bank or the Agent to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this
Agreement, the other Loan Documents, any Letters of Credit, such Bank’s Commitment or the Loans (other than taxes based upon or measured by the income or profits of such Bank or the Agent), or 
  

 -48- 








 (b) materially change the basis of taxation (except for changes in taxes on income or
profits) of payments to any Bank of the principal of or the interest on any Loans or any other amounts payable to the Agent or any Bank under this Agreement or the other Loan Documents, or 
 (c) impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or letters of credit issued by, or
commitments of an office of any Bank, or 
 (d) impose on any Bank or the Agent any other conditions or requirements with
respect to this Agreement, the other Loan Documents, any Letters of Credit, the Loans, such Bank’s Commitment, or any class of loans, letters of credit or commitments of which any of the Loans or such Bank’s Commitment forms a part;

 and the result of any of the foregoing is 
 (i) to increase the cost to any Bank of making, funding, issuing, renewing, extending or maintaining any of the Loans or such Bank’s Commitment or any Letter of Credit, or 
 (ii) to reduce the amount of principal, interest, Reimbursement Obligation or other amount payable to such Bank or the Agent hereunder on
account of such Bank’s Commitment, any Letter of Credit or any of the Loans, or 
 (iii) to require such Bank or the
Agent to make any payment or to forego any interest or Reimbursement Obligation or other sum payable hereunder, the amount of which payment or foregone interest or Reimbursement Obligation or other sum is calculated by reference to the gross amount
of any sum receivable or deemed received by such Bank or the Agent from the Borrower hereunder, 
 then, and in each such case, the Borrower will, within
thirty (30) days after notice by the Agent or such Bank (such notice to be given promptly by the Agent or such Bank upon the making of any such determination), at any time and from time to time and as often as the occasion therefor may arise,
but subject to the limitations set forth in §5.7, pay to such Bank or the Agent such additional amounts as such Bank or the Agent shall determine in good faith to be sufficient to compensate such Bank or the Agent for such 

  

 -49- 








 
additional cost, reduction, payment or foregone interest or other sum, provided that such Bank or the Agent is generally imposing similar charges on
its other similarly situated borrowers. 
 §5.6. Capital Adequacy. If any future law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law, but if not having the force of law, then generally applied by the Banks with respect to similar loans) or the interpretation thereof by a court or governmental authority with
appropriate jurisdiction affects the amount of capital required or expected to be maintained by banks or bank holding companies and any Bank or the Agent determines that the amount of capital required to be maintained by it is increased by or based
upon the existence of Loans made or deemed to be made pursuant hereto, then such Bank or the Agent may notify the Borrower of such fact, and the Borrower shall pay to such Bank or the Agent from time to time, within thirty (30) days after
notice by the Agent or such Bank (such notice to be given promptly by the Agent or such Bank upon the making of any such determination), as an additional fee payable hereunder, but subject to the limitations set forth in §5.7, such amount as
such Bank or the Agent shall determine reasonably and in good faith and certify in a notice to the Borrower to be an amount that will adequately compensate such Bank in light of these circumstances for its increased costs of maintaining such
capital. Each Bank and the Agent shall allocate such cost increases among its customers in good faith and on an equitable basis, and will not charge the Borrower unless it is generally imposing a similar charge on its other similarly situated
borrowers. 
 §5.7. Certificate; Limitations. A certificate setting forth any additional amounts payable pursuant to
§§5.5 or 5.6 and a brief explanation of such amounts which are due, including reasonably detailed information regarding the method and calculation of such amount, submitted by any Bank or the Agent to the Borrower, shall be prima
facie evidence that such amounts are due and owing. Notwithstanding anything to the contrary contained in this Article 5, (i) to the extent reasonably possible, each Bank shall designate an alternate lending office in the continental
United States to make the Loans in order to reduce any liability of Borrower to such Bank under §§5.4, 5.5 or 5.6 or to avoid the unavailability of a Eurodollar Rate Loan, so long as such designation is not disadvantageous to such Bank,
and (ii) the Borrower shall not be obligated to compensate any Bank pursuant to §§5.4, 5.5 or 5.6 for any amounts attributable to any period which is more than one (1) year prior to the date of delivery of the certificate set
forth in the first sentence of this §5.7. If (a) a Bank requests compensation pursuant to §§5.5 or 5.6 and the Required Banks are not also doing the same, or (b) the obligation of any Bank to make, convert and/or continue
Eurodollar Rate Loans shall be suspended pursuant to §5.4 but the obligation of the Required Banks shall not have been suspended under such Section, then, so long as there does not then exist any Default or Event of Default, the Borrower,
within thirty (30) days of such request for compensation or suspension, as applicable, may either (x) demand that such Bank (the “Affected Bank”) assign its Commitment to an Eligible Assignee designated by Borrower (or designated
by Agent and approved by Borrower), and upon such demand the Affected Bank shall promptly assign its Commitment to such Eligible Assignee, subject to and in accordance with the provisions of §20.1 for a purchase price equal to the aggregate
principal balance of the 

  

 -50- 








 
Loans then owing to the Affected Bank plus any accrued but unpaid interest thereon and accrued but unpaid fees owing to the Affected Bank, (y) pay to
the Affected Bank the amounts required under §§5.4, 5.5 or 5.6, as applicable or (z) pay to the Affected Bank the aggregate principal balance of the Loans then owing to the Affected Bank plus any accrued but unpaid interest thereon
and accrued but unpaid fees owing to the Affected Bank (but without duplication of the amounts payable pursuant to §§5.4, 5.5 or 5.6, as applicable). If Borrower elects either option (x) or (z) above, it shall, in all events, pay
to the Affected Bank the amounts required under §§5.4, 5.5 or 5.6, as applicable, for the period prior to such replacement or termination of the Affected Bank, and upon any such election the Affected Bank shall no longer be a party hereto
or have any rights or obligations hereunder (other than with respect to §§5.5, 5.6, 17 and 18 for the period prior to the replacement or termination of the Affected Bank) or under any of the other Loan Documents. Each of the Agent and the
Affected Bank shall reasonably cooperate in effectuating the replacement of the Affected Bank under this Section, but at no time shall the Agent, the Affected Bank or any other Bank be obligated in any way whatsoever to initiate any such replacement
or to assist in finding an Eligible Assignee. The exercise by the Borrower of its rights under this Section shall be at the Borrower’s sole cost and expense and at no cost or expense to the Agent, the Affected Bank or any of the other Banks.

 §5.8. Indemnity. In addition to the other provisions of this Agreement regarding such matters, the Borrower agrees to
indemnify the Agent and each Bank and to hold the Agent and each Bank harmless from and against any loss, cost or expense (including loss of the spread to which such Bank would have been entitled through the end of the applicable Interest Period in
excess of the applicable interest rate(s) then in effect) that the Agent or such Bank may sustain or incur as a consequence of (a) a default by the Borrower in the payment of any principal amount of or any interest on any Eurodollar Rate Loans
as and when due and payable, including any such loss or expense arising from interest or fees payable by the Agent or such Bank to lenders of funds obtained by it in order to maintain its Eurodollar Rate Loans, (b) the failure by the Borrower

(x) conduct all or substantially all of its business operations through the Borrower or through subsidiary partnerships or other entities in which the Borrower owns at least 99% of the economic interests and (y) own no real property or
material personal property other than (1) through its ownership interests in the Borrower and its Subsidiaries, including Boston Properties LLC, in compliance with the terms hereof, and (2) contracts and agreements of the nature described

repair and working order, and supplied with all necessary equipment, (b) to cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of BPI may be necessary so that the
business carried on in connection therewith may be properly and advantageously conducted at all times and (c) to cause each of its Subsidiaries to continue to engage primarily in the businesses now conducted by it and in related businesses, in
each case under clauses (a), (b) and (c) above to the extent, in the sole judgment of BPI (exercised in good faith), necessary to properly and advantageously conduct the businesses being conducted by it, except to the extent that the
failure to comply with the provisions thereof constitutes a Non-Material Breach. 
 §8.8. Insurance. The Borrower will, and will
cause BPI to, maintain with respect to its properties, and will cause each of its Subsidiaries to maintain with financially sound and reputable insurers, insurance with respect to such properties and its business against such casualties and

to, pay or cause to be paid real estate taxes, other taxes, assessments and other governmental charges against the Real Estate Assets before the same become delinquent and will duly pay and discharge, or cause to be paid and discharged, before the
same shall become overdue, all taxes, assessments and other governmental charges imposed upon its sales and activities, or any part thereof, or upon the income or profits therefrom, as well as all claims for labor, materials, or supplies that if
unpaid might by law become a lien or charge upon any of the Real Estate Assets, unless any failure to do so is a Non-Material Breach; provided that any such tax, assessment, charge, levy or claim need not be paid if the validity or amount
thereof shall currently be contested in good faith by appropriate proceedings and if the Borrower or BPI shall have set aside on its books adequate reserves with respect thereto; and provided further that the Borrower or BPI will pay all such
taxes, assessments, charges, levies or claims forthwith prior to the consummation of proceedings to foreclose any lien that may have attached as security therefor. Promptly upon request by the Agent if required for bank regulatory compliance
purposes or similar bank purposes, the Borrower will provide evidence of the payment of real estate taxes, other taxes, assessments and other governmental charges against the Real Estate Assets in the form of receipted tax bills or other form
reasonably acceptable to the Agent, or evidence of the existence of applicable contests as contemplated herein. 
 §8.10. Inspection
of Properties and Books. (a) Subject to the rights of tenants to limit or prohibit such access, as denoted in the applicable leases, the Borrower will, and will cause BPI to, permit the Agent or any of the Banks’ other designated
representatives upon no less than 24 hours notice (which notice may be given orally or in writing), to visit and inspect any of the properties of the Borrower, BPI or any of their respective Subsidiaries to examine the books of account of the
Borrower, BPI and their respective Subsidiaries (and to make copies thereof and extracts therefrom) and to discuss the affairs, finances and accounts of the Borrower, BPI and their respective Subsidiaries with, and to be advised as to the same by,
its officers, all at such reasonable times and intervals as the Agent may reasonably request; provided that, so long as no Event of Default has occurred and is continuing, the Borrower shall only be responsible for the costs and expenses

and all materials of any kind (including opinions or other tax analyses) that are or have been provided to such Bank or the Agent related to such structure and tax aspects. In this regard, each of the Banks and the Agent acknowledges and agrees that
its disclosure of the structure or tax aspects of the Facility is not limited in any way by an express or implied understanding or agreement, oral or written (whether or not such understanding or agreement is legally binding). Furthermore, each of
the Banks and the Agent acknowledges and agrees that it does not know or have reason to know that 

  

 -64- 








 
its use or disclosure of information relating to the structure or tax aspects of the Facility is limited in any other manner (such as where the Facility is
claimed to be proprietary or exclusive) for the benefit of any other Person. Notwithstanding the foregoing (i) the Banks and the Agent shall not disclose any materials or information of any kind or nature whatsoever which are not specifically
permitted to be disclosed in accordance with the terms of this subparagraph (b) and (ii) in the event of any change, amendment, modification or clarification of Code sections 6011 and/or 6111 (or any other applicable section of the Code)
or any Regulations promulgated thereunder, or the issuance by any Person of any guidance on which the Banks, the Agent and the Representatives are entitled to rely or are otherwise bound by (including, by way of example only, private letter
rulings), which in any way limits or restricts what may be disclosed pursuant to the terms of this paragraph, or otherwise establishes that such Code sections do not, or are not intended to, apply to loan facilities such as the Facility (or other
similar transactions), the terms of this subparagraph (b) shall be deemed modified thereby. In this regard, the Banks and the Agent intend that this transaction will not be a “confidential transaction” under Code sections 6011, 6111
or 6112, and the regulations promulgated thereunder. 
 (c) Notwithstanding anything to the contrary herein (including,
without limitation, the provisions of subparagraph (b) above), neither the Agent nor any Bank may disclose to any Person any information that constitutes material non-public information regarding the Borrower or its securities for purposes of
Regulation FD of the Securities and Exchange Commission or any other federal or state securities laws (it being acknowledged and agreed that the provisions of this §8.10 with respect to such information are reasonably necessary to comply with
said Regulation FD and/or such other federal and state securities laws) (such information referred to collectively herein as the “Borrower Information”), except that each of the Agent and each of the Banks may disclose Borrower Information
(i) to any other Bank, (ii) to any other person if reasonably incidental to the administration of the Loans, (iii) upon the order of any court or administrative agency, (iv) upon the request or demand of any regulatory agency or
authority, (v) which has been publicly disclosed other than as a result of a disclosure by the Agent or any Bank which is not permitted by this Agreement, (vi) in connection with any litigation to which the Agent, any Bank, or any other
Representative may be a party, (vii) to the extent reasonably required in connection with the exercise of any remedy hereunder, (viii) to the Agent’s or such Bank’s Affiliates, legal counsel and independent auditors or other
Representatives, and (ix) to any actual or proposed participant or Eligible Assignee of all or part of its rights hereunder. 
 (d) Each of the Banks and the Agent hereby agrees that the Borrower (and its, and its affiliates’, employees, officers, directors, advisors and agents (collectively “Borrower Representatives”) is, and has been from the
commencement of discussions with respect to the Facility, permitted to disclose to any and all Persons, without limitation of any kind, the structure and tax aspects (as such terms are used in Code sections 6011 and 6111) of the Facility, and all
materials of any kind (including opinions or other tax analyses) that are or have been provided to the Borrower related to such structure and tax aspects. In this regard, the Borrower acknowledges and agrees that its disclosure of the structure or
tax aspects of the Facility is not limited in any way by an 

  

 -65- 








 
express or implied understanding or agreement, oral or written (whether or not such understanding or agreement is legally binding). Furthermore, each of the
Borrower, each Bank and the Agent acknowledges and agrees that it does not know or have reason to know that its use or disclosure of information relating to the structure or tax aspects of the Facility is limited in any other manner (such as where
the Facility is claimed to be proprietary or exclusive) for the benefit of any other Person. 
 (e) The Borrower hereby
acknowledges that (a) the Agent and/or the Arrangers will make available to the Banks and the Fronting Bank materials and/or information provided by or on behalf of the Borrower hereunder by posting such materials on IntraLinks or another
similar electronic system (the “Platform”) and (b) certain of the Banks may be “public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Borrower or
its securities) (each, a “Public Lender”). The Borrower hereby agrees that (w) all such materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum,
shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking such materials “PUBLIC,” the Borrower shall be deemed to have authorized the Agent, the Arrangers, the Fronting Bank and
the Banks to treat such materials as not containing any material non-public information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws; (y) all such materials marked
“PUBLIC” are permitted to be made available through a portion of the Platform designated “Public Investor;” and (z) the Agent and the Arrangers shall be entitled to treat any such materials that are not marked
“PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Investor.” Notwithstanding the foregoing, Borrower shall be under no obligation to mark any such materials “PUBLIC.” In
addition, Agent, Arrangers, the Fronting Bank and the Banks all agree to maintain all such materials (other than any such materials as are marked “PUBLIC”) in confidence and further agree that they shall not make any such materials
available to any other Person (including, without limitation, other proposed Banks and/or participants) unless and until such other Person agrees to maintain such materials in confidence; provided, disclosures made pursuant to clauses (iii), (iv),
(v), (vi) and (vii) of §8.10(c), shall not be subject to this last sentence of this §8.10(e). 
 (f) The
provisions of this §8.10 supersede any confidentiality obligations of the Borrower, the Agent or any of the Banks relating to the Facility under any agreements between or among the Borrower and the Agent and/or the Banks, as applicable. The
parties hereto agree that any such confidentiality obligations shall be deemed void ab initio. 
 §8.11. Compliance with Laws,
Contracts, Licenses, and Permits. The Borrower will, and will cause BPI to, comply with, and will cause each of their respective Subsidiaries to comply with (a) all applicable laws and regulations now or hereafter in effect wherever its
business is conducted, including, without limitation, all Environmental Laws and all applicable federal and state securities laws, (b) the provisions of its partnership agreement or corporate charter and other charter documents 

  

 -66- 








 
and by-laws, as applicable, (c) all material agreements and instruments to which it is a party or by which it or any of its properties may be bound
(including the Real Estate Assets and the Leases) and (d) all applicable decrees, orders, and judgments, unless such non-compliance constitutes a Non-Material Breach. If at any time while any Loan or Note or Letter of Credit is outstanding or
the Banks have any obligation to make Loans or issue Letters of Credit hereunder, any Permit shall become necessary or required in order that the Borrower may fulfill any of its obligations hereunder, the Borrower and BPI and their respective
Subsidiaries will immediately take or cause to be taken all reasonable steps within the power of the Borrower or BPI, as applicable, to obtain such Permit and furnish the Agent with evidence thereof. 
 §8.12. Use of Proceeds. Subject at all times to the other provisions of this Agreement, the Borrower will use the proceeds of the Loans
solely for working capital and general corporate purposes. It is agreed by the Banks that, from time to time, the Borrower may request proceeds of the Loans be used to refinance certain secured mortgage Indebtedness of the Borrower and/or its
Subsidiaries, in which event, a portion of the Loans equal to the amount of the advances made hereunder in connection with such refinancing may, at Borrower’s election, be secured by the refinanced mortgage (a “Refinancing Mortgage”).
Any such Refinancing Mortgage would be (i) required to be in form and substance reasonably satisfactory to the Agent, (ii) subject to customary terms and conditions reasonably satisfactory to the Agent, (iii) amended and restated to
provide for economic and other terms which are identical to those of the Loans (e.g., the maturity date shall be amended to be the Maturity Date hereunder and the interest rate and payment terms will be amended to be the same as those hereunder, it
being further acknowledged that such modified interest rate may be based upon either a Revolving Credit Loan or a Bid Rate Loan calculation, as elected by the Borrower pursuant to the terms hereof) and (iv) subject to being released or
transferred by the Agent at the request of the Borrower. In addition, in connection with each Refinancing Mortgage, the Agent would agree to provide, at the request of Borrower, subordination, non-disturbance and attornment agreements in form and
substance reasonably satisfactory to Agent. No Real Estate Asset that is subject to a Refinancing Mortgage will qualify as an Unencumbered Asset hereunder. 
 §8.13. Intentionally Deleted. 
 §8.14. Solvency. Each of Borrower, BPI and their
respective Subsidiaries shall remain solvent at all times, unless such failure to remain solvent does not relate to Borrower or BPI and is a Non-Material Breach. 
 §8.15. Further Assurances. The Borrower will, and will cause BPI to, cooperate with, the Agent and the Banks and execute such further instruments and documents as the Banks or the Agent shall reasonably
request to carry out to their satisfaction the transactions contemplated by this Agreement and the other Loan Documents. 
 §8.16.
Intentionally Deleted.

 §8.17. Environmental Indemnification. The Borrower covenants and agrees that it will
indemnify and hold the Agent and each Bank, and each of their respective Affiliates, harmless from and against any and all claims, expense, damage, loss or liability incurred by the Agent or any Bank (including all reasonable costs of legal
representation incurred by the Agent or any Bank, but excluding, as applicable, for the Agent or a Bank any claim, expense, damage, loss or liability as a result of the gross negligence or willful misconduct of the Agent or such Bank or any of their
respective Affiliates) relating to (a) any Release or threatened Release of Hazardous Substances on any Real Estate Asset; (b) any violation of any Environmental Laws with respect to conditions at any Real Estate Asset or the operations
conducted thereon; (c) the investigation or remediation of off-site locations at which the Borrower, BPI or any of their respective Subsidiaries or their predecessors are alleged to have directly or indirectly disposed of Hazardous Substances;
or (d) any action, suit, proceeding or investigation brought or threatened with respect to any Hazardous Substances relating to Real Estate Assets (including, but not limited to, claims with respect to wrongful death, personal injury or damage
to property). It is expressly acknowledged by the Borrower that, notwithstanding the introductory paragraph of this §8, this covenant of indemnification shall survive the repayment of the amounts owing under the Notes and this Agreement and the
termination of this Agreement and the obligations of the Banks hereunder and shall inure to the benefit of the Agent and the Banks and their respective Affiliates, their respective successors, and their respective assigns under the Loan Documents
permitted under this Agreement. 
 §8.18. Response Actions. The Borrower covenants and agrees that if any Release or disposal of
Hazardous Substances shall occur or shall have occurred on any Real Estate Asset owned directly or indirectly by the Borrower or BPI, in material violation of applicable Environmental Laws, the Borrower will cause the prompt containment and removal
of such Hazardous Substances and remediation of such wholly-owned Real Estate Asset as necessary to comply in all material respects with all Environmental Laws, unless such non-compliance would constitute a Non-Material Breach. 
 §8.19. Intentionally Deleted. 
 §8.20. Employee Benefit Plans. 
 (a) Notice. The Borrower will, and will cause BPI to, notify the
Agent within a reasonable period after the establishment of any Guaranteed Pension Plan by any of them or any of their respective ERISA Affiliates other than those disclosed in the SEC Filings and no Borrower will, or will permit BPI to, establish
any Multiemployer Plan or Guaranteed Pension Plan which could reasonably be expected to have a material adverse effect on BPLP, BPI or, taken as a whole, the BP Group. 
 (b) In General. Each Employee Benefit Plan maintained by the Borrower, BPI or any of their respective ERISA Affiliates will be
operated in compliance in all material respects with the provisions of ERISA and, to the extent applicable, the Code, including but not limited to the provisions thereunder respecting prohibited transactions. 
  

 -68- 








 (c) Unfunded or Underfunded Liabilities. The Borrower will not, and will not
permit BPI to, at any time, have accruing or accrued unfunded or underfunded liabilities with respect to any Employee Benefit Plan, Guaranteed Pension Plan or Multiemployer Plan, or permit any condition to exist under any Multiemployer Plan that
would create a withdrawal liability, which such liability could, individually or in the aggregate, reasonably be expected to have a material adverse effect on BPLP, BPI or, taken as a whole, the BP Group. 
 §8.21. No Amendments to Certain Documents. The Borrower will not, and will not permit BPI to, at any time cause or permit its certificate of
limited partnership, agreement of limited partnership (including without limitation the Agreement of Limited Partnership of the Borrower, articles of incorporation, by-laws, operating agreement or other charter documents, as the case may be), to be
modified, amended or supplemented in any respect whatever, without (in each case) the express prior written consent or approval of the Agent, if such changes would affect BPI’s REIT status or otherwise materially adversely affect the rights of
the Agent and the Banks hereunder or under any other Loan Document. 
 §9. CERTAIN NEGATIVE COVENANTS OF THE BORROWER AND BPI.
The Borrower for itself and on behalf of BPI covenants and agrees that, so long as any Loan, Letter of Credit or Note is outstanding or any Bank has any obligation to make any Loans or any Bank has any obligation to issue, extend or renew any
Letters of Credit:

except as specifically noted in clauses (a) through (e) below, neither the Borrower nor BPI will, or will permit any Subsidiary to, create, incur, assume, guarantee or be or remain liable for, contingently or otherwise, singularly or in
the aggregate for any of such Prohibited Liabilities, as follows:

and which is not being contested diligently and in good faith; 
  

 -69- 








 (d) An aggregate amount in excess of $20,000,000 at any one time in respect of uninsured

thirty (30) days; and 
 (e) With respect to BPI only, any and all Liabilities other than (i) the Liabilities

 Notwithstanding any other provision of this Agreement, in the event that any Subsidiary of BPLP incurs Unsecured Indebtedness, (i) the Real Estate
Assets owned by such Subsidiary shall not be treated as Unencumbered Assets for purposes of this Agreement until such Unsecured Indebtedness has been repaid and the loan documents evidencing such Unsecured Indebtedness have been terminated and
(ii) no Default or Event of Default may result from the incurrence of such Unsecured Indebtedness, and after giving effect to such Unsecured Indebtedness (and to the exclusion of any Unencumbered Assets owned by the applicable Subsidiary), the
Borrower must be in compliance with each of the covenants set forth in §10. 
 Without limiting the foregoing, but subject to the other
provisions of this Agreement (including without limitation §10), Indebtedness Without Recourse to Borrower or any of its assets other than its interests in the Real Estate Assets that are subject to such Indebtedness Without Recourse is not

this Agreement or the other Loan Documents or any instrument pursuant to which the Obligations are evidenced and, to the full extent permitted by applicable law, the obtaining of the ex parte appointment of a receiver), and, if any amount
shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any other legal or equitable right or remedy of the Agent and the Banks under the Loan Documents or applicable law. No remedy herein conferred upon the

Documents. The Agent may utilize the services of such Persons as the Agent in its sole discretion may reasonably determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrower. 
 §16.3. No Liability. Neither the Agent, nor any of its shareholders, directors, officers or employees nor any other Person assisting them in
their duties nor any agent or employee thereof, shall be liable for any waiver, consent or approval given or any action taken, or omitted to be taken, in good faith by it or them hereunder or under any of the other Loan Documents, or in connection

 §16.4. No Representations. The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Notes,
the Letters of Credit, or any of the other Loan Documents or for the validity, enforceability or collectibility of any such amounts owing with respect to the Notes, or for any recitals or statements, warranties or representations made herein or in
any of the other Loan Documents or in any certificate or instrument hereafter furnished to it by or on behalf of BPI or the Borrower or any of their respective Subsidiaries, or be bound to ascertain or inquire as to the performance or observance of
any of the terms, conditions, covenants or agreements in this Agreement or the other Loan Documents. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by the Borrower or BPI or any holder of any
of the Notes shall have been duly authorized or is true, accurate and complete. The Agent has not made nor does it now make any representations or warranties, express or implied, nor does it assume any liability to the Banks, with respect to the
credit worthiness or financial condition of the Borrower or any of its Subsidiaries or BPI or any of the Subsidiaries or any tenant under a Lease or any other entity. Each Bank acknowledges that it has, independently and without reliance upon the
Agent or any other 

  

 -85- 








 
Bank, and based upon such information and documents as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

 §16.5. Payments. 
 (a) A payment by the Borrower to the Agent hereunder or any of the other Loan Documents for the account of any Bank shall constitute a payment to such Bank. The Agent agrees to distribute to each Bank such Bank’s
pro rata share of payments received by the Agent for the account of the Banks, as provided herein or in any of the other Loan Documents. All such payments shall be made on the date received, if before 1:00 p.m., and if after 1:00 p.m.,
on the next Business Day. 
 (b) If in the reasonable opinion of the Agent the distribution of any amount received by it in
such capacity hereunder, under the Notes or under any of the other Loan Documents might involve it in material liability, it may refrain from making the distribution until its right to make the distribution shall have been adjudicated by a court of
competent jurisdiction, provided that the Agent shall invest any such undistributed amounts in overnight obligations on behalf of the Banks and interest thereon shall be paid pro rata to the Banks. If a court of competent
jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid, each Person to whom any such distribution shall have been made shall either repay to the Agent its proportionate share of the amount so adjudged to be
repaid or shall pay over the same in such manner and to such Persons as shall be determined by such court. 
 (c)
Notwithstanding anything to the contrary contained in this Agreement or any of the other Loan Documents, any Bank that fails (i) to make available to the Agent its pro rata share of any Loan or to purchase any Letter of Credit
Participation or (ii) to adjust promptly such Bank’s outstanding principal and its pro rata Commitment Percentage as provided in §2.1, shall be deemed delinquent (a “Delinquent Bank”) and shall be deemed a
Delinquent Bank until such time as such delinquency is satisfied. A Delinquent Bank shall be deemed to have assigned any and all payments due to it from the Borrower, whether on account of outstanding Loans, interest, fees or otherwise, to the
remaining nondelinquent Banks for application to, and reduction of, their respective pro rata shares of all outstanding Loans. The Delinquent Bank hereby authorizes the Agent to distribute such payments to the nondelinquent Banks in
proportion to their respective pro rata shares of all outstanding Loans. If not previously satisfied directly by the Delinquent Bank, a Delinquent Bank shall be deemed to have satisfied in full a delinquency when and if, as a result of
application of the assigned payments to all outstanding Loans of the nondelinquent Banks, the Banks’ respective pro rata shares of all outstanding Loans have returned to those in effect immediately prior to such delinquency and
without giving effect to the nonpayment causing such delinquency. 
 §16.6. Holders of Notes. The Agent may deem and treat the
payee of any Notes or the purchaser of any Letter of Credit Participation as the absolute owner or purchaser thereof for all purposes hereof until it shall have been furnished in writing with a different name by such payee or by a subsequent holder,
assignee or transferee. 
  

 -86- 








 §16.7. Indemnity. The Banks ratably and severally agree hereby to indemnify and hold harmless
the Agent and its Affiliates from and against any and all claims, actions and suits (whether groundless or otherwise), losses, damages, costs, expenses (including any expenses for which the Agent has not been reimbursed by the Borrower as required
by §17), and liabilities of every nature and character arising out of or related to this Agreement, the Notes, or any of the other Loan Documents or the transactions contemplated or evidenced hereby or thereby, or the Agent’s actions taken
hereunder or thereunder, except to the extent that any of the same shall be directly caused by the Agent’s willful misconduct or gross negligence. 
 §16.8. Agent as Bank. In its individual capacity as a Bank, BOA shall have the same obligations and the same rights, powers and privileges in respect to its Commitment and the Loans made by it, and as the
holder of any of the Notes and as the purchaser of any Letter of Credit Participations, as it would have were it not also the Agent. 
 §16.9. Notification of Defaults and Events of Default. Each Bank hereby agrees that, upon learning of the existence of a Default or an Event of Default, it shall (to the extent notice has not previously been provided) promptly
notify the Agent thereof. The Agent hereby agrees that upon receipt of any notice under this §16.9 it shall promptly notify the other Banks of the existence of such Default or Event of Default. 
 §16.10. Duties in the Case of Enforcement. In case one or more Events of Default have occurred and shall be continuing, and whether or not
acceleration of the Obligations shall have occurred, the Agent shall, if (a) so requested by the Required Banks and (b) the Banks have provided to the Agent such additional indemnities and assurances against expenses and liabilities as the
Agent may reasonably request, proceed to enforce the provisions of this Agreement and exercise all or any such other legal and equitable and other rights or remedies as it may have in respect of enforcement of the Banks’ rights against the
Borrower and its Subsidiaries under this Agreement and the other Loan Documents. The Required Banks may direct the Agent in writing as to the method and the extent of any such enforcement, the Banks (including any Bank which is not one of the
Required Banks) hereby agreeing to ratably and severally indemnify and hold the Agent harmless from all liabilities incurred in respect of all actions taken or omitted in accordance with such directions, provided that the Agent need not
comply with any such direction to the extent that the Agent reasonably believes the Agent’s compliance with such direction to be unlawful or commercially unreasonable in any applicable jurisdiction. 
 §16.11. Successor Agent. BOA, or any successor Agent, may resign as Agent at any time by giving at least 30 days prior written notice thereof
to the Banks and to the Borrower. The Required Banks may remove the Agent in the event of the Agent’s willful misconduct or gross negligence or in the event that the Bank serving as Agent ceases to hold a Commitment under this Agreement. In
addition, the Borrower may remove the Agent in the event that the Agent holds (without participation) less than the Minimum Commitment, provided that Borrower shall not have such removal right if an Event of 

  

 -87- 








 
Default exists or if the Agent holds less than the Minimum Commitment at any time as a result of the merger or consolidation of any of the other Banks or as
a result of events other than the sale by the Agent of any portion of its Commitment. Any such resignation or removal shall be effective upon appointment and acceptance of a successor Agent, as hereinafter provided. Upon any such resignation or
removal, the Required Banks shall have the right to appoint a successor Agent, which is a Bank under this Agreement and which holds at least the Minimum Commitment, provided that so long as no Default or Event of Default has occurred and is
continuing the Borrower shall have the right to approve any successor Agent, which approval shall not be unreasonably withheld. If, in the case of a resignation by the Agent, no successor Agent shall have been so appointed by the Required Banks and
approved by the Borrower, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Banks, appoint any one of the other Banks
as a successor Agent. The Borrower acknowledges that any Bank which acquires BOA is acceptable as a successor Agent. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring or removed Agent, and the retiring or removed Agent shall be discharged from all further duties and obligations as Agent under this Agreement. After any Agent’s
resignation or removal hereunder as Agent, the provisions of this §16 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. The Agent agrees that it shall not assign any of its
rights or duties as Agent to any other Person. 
 §16.12. Notices. Any notices or other information required hereunder to be
provided to the Agent shall be forwarded by the Agent to each of the Banks on the same day (if practicable) and, in any case, on the next Business Day following the Agent’s receipt thereof. Notwithstanding the foregoing, it is agreed by the
Banks that the Agent shall have no obligation to send to the Banks the information which is deemed delivered by the Borrower under §8.4 by the Borrower’s filing with the SEC of its Form 10-Q and Form 10-K, all as more particularly
described in the last paragraph of §8.4, and the Agent shall have no liability to any Person for any Bank’s failure to obtain such SEC filings. 
 §17. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of producing and reproducing this Agreement, the other Loan Documents and the other agreements and instruments mentioned herein,
(b) directly to the party owed the same, the reasonable fees, expenses and disbursements of the Agent’s outside counsel or any local counsel to the Agent incurred in connection with the preparation, administration or interpretation of the
Loan Documents and other instruments mentioned herein, each closing hereunder, and amendments, modifications, approvals, consents or waivers hereto or hereunder, (c) the fees, expenses and disbursements of the Agent incurred by the Agent in
connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, and, without double-counting amounts under clause (b) above, the fees and disbursements of the Agent’s counsel
in preparing the documentation, (d) the fees, costs, expenses and disbursements of the Agent and its Affiliates incurred in connection with the initial syndication and/or 

  

 -88- 








 
participations of the Loans (whether occurring before or after the closing hereunder), including, without limitation, reasonable legal fees, travel costs,
costs of preparing syndication materials and photocopying costs, provided that the Borrower shall not incur any costs or fees of any kind in connection with any participation, sale or other syndication of any portion of the Loans which occurs
after the initial syndication other than reasonable legal fees and expenses incurred in connection with any participation, sale or syndication undertaken at the request of the Borrower or (in addition to any other fees or expenses relating thereto)
in connection with an amendment or increase to the amount of the Total Commitment, (e) all reasonable expenses (including reasonable attorneys’ fees and costs, which attorneys may be employees of any Bank or the Agent, and the fees and
costs of engineers, investment bankers, or other experts retained by any Bank or the Agent in connection with any such enforcement proceedings) incurred by any Bank or the Agent in connection with (i) the enforcement of or preservation of
rights under any of the Loan Documents against the Borrower or any of its Subsidiaries or BPI or the administration thereof after the occurrence and during the continuance of a Default or Event of Default (including, without limitation, expenses
incurred in any restructuring and/or “workout” of the Loans), and (ii) any litigation, proceeding or dispute whether arising hereunder or otherwise, in any way related to any Bank’s or the Agent’s relationship with the
Borrower or any of its Subsidiaries or BPI, and (f) all reasonable fees, expenses and disbursements of the Agent incurred in connection with UCC searches, UCC terminations or mortgage discharges. The covenants of this §17 shall survive the
repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Banks hereunder. 
 §18. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the Agent, Arrangers, JPM, JPChase, the Banks and each of their respective Related Parties (each an “Indemnified Party”) from and against any and
all claims, actions and suits, whether groundless or otherwise, and from and against any and all liabilities, losses (including amounts, if any, owing to any Bank pursuant to §§5.4, 5.5, 5.6 and 5.8), settlement payments, obligations,
damages and expenses of every nature and character in connection therewith, arising out of this Agreement or any of the other Loan Documents or the transactions contemplated hereby or thereby or which otherwise arise in connection with this
financing, including, without limitation, (a) any actual or proposed use by the Borrower or any of its Subsidiaries of the proceeds of any of the Loans, (b) the Borrower or any of its Subsidiaries entering into or performing this Agreement
or any of the other Loan Documents, or (c) pursuant to §8.17, in each case including, without limitation, the reasonable fees and disbursements of counsel and allocated costs of internal counsel incurred in connection with any such
investigation, litigation or other proceeding, provided, however, that the Borrower shall not be obligated under this §18 to indemnify any Indemnified Party for liabilities arising from such Indemnified Party’s own gross
negligence, willful misconduct or bad faith breach of this Agreement. In litigation, or the preparation therefor, the Borrower shall be entitled to select counsel reasonably acceptable to the Required Banks, and the Agent (as approved by the
Required Banks) shall be entitled to select their own supervisory counsel, and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses of each such counsel. Prior to any settlement of any 

  

 -89- 








 
such litigation by the Banks, the Banks shall provide the Borrower and BPI with notice and an opportunity to address any of their concerns with the Banks,
and the Banks shall not settle any litigation without first obtaining Borrower’s consent thereto, which consent shall not be unreasonably withheld or delayed. If and to the extent that the obligations of the Borrower under this §18 are
unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment in satisfaction of such obligations which is permissible under applicable law. The provisions of this §18 shall survive the repayment of
the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Banks hereunder and shall continue in full force and effect as long as the possibility of any such claim, action, cause of action
or suit exists. 
 §19. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations and warranties made herein, in the
Notes, in any of the other Loan Documents or in any documents or other papers delivered by or on behalf of the Borrower or any of its Subsidiaries or BPI pursuant hereto shall be deemed to have been relied upon by the Banks and the Agent,
notwithstanding any investigation heretofore or hereafter made by any of them, and shall survive the making by the Banks of any of the Loans and the issuance, extension or renewal of any Letters of Credit, as herein contemplated, and shall continue
in full force and effect so long as any Letter of Credit or any amount due under this Agreement or the Notes or any of the other Loan Documents remains outstanding or any Bank has any obligation to make any Loans or the Agent or any Fronting Bank
has any obligation to issue, extend or renew any Letter of Credit. The indemnification obligations of the Borrower provided herein and in the other Loan Documents shall survive the full repayment of amounts due and the termination of the obligations
of the Banks hereunder and thereunder to the extent provided herein and therein. All statements contained in any certificate or other paper delivered to any Bank or the Agent at any time by or on behalf of the Borrower or any of its Subsidiaries or
BPI pursuant hereto or in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower or such Subsidiary or BPI hereunder. 
 §20. ASSIGNMENT; PARTICIPATIONS; ETC. 
 §20.1. Conditions to Assignment by Banks. Except as provided herein, each Bank may assign to one or more Eligible Assignees all or a portion of its interests, rights and obligations under this Agreement (including all or a
portion of its Commitment Percentage and Commitment and the same portion of the Loans at the time owing to it, the Notes held by it and its participating interest in the risk relating to any Letters of Credit); provided that (a) the
Agent, Swingline Lender and Fronting Bank and, other than during an Event of Default, the Borrower each shall have the right to approve any Eligible Assignee, which approval shall not be unreasonably withheld or delayed, it being agreed that the
Agent, the Borrower, Swingline Lender and Fronting Bank, as applicable, must approve or reject a proposed Eligible Assignee within seven (7) days of receiving a written request from any Bank for such approval (provided that the request
for approval sent to each of Agent, Borrower, Swingline Lender and Fronting Bank, respectively, is 

  

 -90- 








 
conspicuously marked with the following legend: “REQUEST FOR APPROVAL — TIME SENSITIVE — MUST RESPOND WITHIN SEVEN (7) DAYS”) and if
the Agent, the Borrower, Swingline Lender or Fronting Bank, as applicable, fails to respond within such seven (7) day period, such request for approval shall be deemed approved by, respectively, the Agent, the Borrower, Swingline Lender and
Fronting Bank, as the case may be, (b) each such assignment shall be of a constant, and not a varying, percentage of all the assigning Bank’s rights and obligations under this Agreement, (c) subject to the provisions of §2.7,

“Assignment and Assumption”), together with any Notes subject to such assignment. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Assumption, which effective date
shall be at least two (2) Business Days after the execution thereof unless otherwise agreed by the Agent (provided any assignee has assumed the obligation to fund any outstanding Eurodollar Rate Loans), (i) the assignee thereunder
shall be a party hereto and, to the extent provided in such Assignment and Assumption, have the rights and obligations of a Bank hereunder and thereunder, and (ii) the assigning Bank shall, to the extent provided in such assignment and upon
payment to the Agent of the registration fee referred to in §20.3, be released from its obligations under this Agreement. Any such Assignment and Assumption shall run to the benefit of the Borrower and a copy of any such Assignment and
Assumption shall be delivered by the Assignor to the Borrower. 
 Notwithstanding the provisions of subclause (a) of the preceding
paragraph, any Bank may, without the consent of the Borrower, make an assignment otherwise permitted hereunder to (x) another Bank, and (y) an Affiliate of such Bank, provided that such Affiliate is an Eligible Assignee. Without
limiting the provisions of §17, with respect to an assignment by a Bank to its Affiliate or to another Bank which does not require the consent of the Borrower, unless such assignment occurs at the request of the Borrower, the Borrower shall not
be responsible for any costs or expenses attributable to such assignment, all of which shall be payable by the assigning Bank. 
 §20.2.
Certain Representations and Warranties; Limitations; Covenants. By executing and delivering an Assignment and Assumption, the parties to the assignment thereunder confirm to and agree with each other and the other parties hereto as follows:

furnished pursuant hereto or thereto; (c) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in §7.4 and §8.4 and such other documents and

of, and principal amount of the Loans owing to, the Banks from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Agent and the Banks may treat each Person whose name is recorded in
the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and the Banks at any reasonable time and from time to time upon reasonable prior notice. Upon each such recordation,

(b) any such sale or participation shall not affect the rights and duties of the selling Bank hereunder to the Borrower and the Agent and the Bank shall continue to exercise all approvals, disapprovals and other functions of a Bank, and
(c) the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of, or approvals under, the Loan Documents shall be the rights to approve waivers, amendments or

entitled or extend any regularly scheduled payment date for principal or interest. 
 §20.6. Pledge by Lender. Notwithstanding
any other provision of this Agreement, any Bank at no cost to the Borrower may at any time pledge all or any portion of its interest and rights under this Agreement (including all or any portion of its Notes) to any of the twelve Federal Reserve

incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms 

  

 -95- 








 
thereof, as understood by the recipient, varied from any confirmation thereof. The Borrower shall indemnify the Agent, the Arrangers, the Swingline Lender,
the Fronting Bank, each Bank and the Related Parties of each of them from all losses, costs, expenses and liabilities resulting from the good faith reliance by such Person on each notice purportedly given by or on behalf of the Borrower, provided,
however, that the Borrower shall have no liability hereunder for any such indemnified party’s gross negligence or willful misconduct in connection therewith. All telephonic notices to and other telephonic communications with the Agent may be

 §27. WAIVER OF JURY TRIAL AND CERTAIN DAMAGE CLAIMS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE BORROWER AND ITS
SUBSIDIARIES HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR

EACH OF THE BORROWER AND ITS SUBSIDIARIES (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY BANK, THE ARRANGERS, THE SWINGLINE LENDER, THE FRONTING BANK OR THE AGENT HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH BANK,
ARRANGERS, SWINGLINE LENDER, FRONTING BANK OR THE AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT THE AGENT, THE ARRANGERS, THE SWINGLINE LENDER, THE FRONTING BANK AND THE BANKS HAVE

 -97- 








 Notwithstanding the foregoing, Unanimous Bank Approval shall be required for any amendment, modification
or waiver of this Agreement that: 
 (i) reduces or forgives any principal of any unpaid Loan or any interest thereon
(including any interest “breakage” costs) or any fees due any Bank hereunder, or permits any prepayment not otherwise permitted hereunder; or 
 (ii) changes the unpaid principal amount of any Loan, reduces the rate of interest applicable to any Loan, or reduces any fee payable to the Banks hereunder; or 
 (iii) changes the date fixed for any payment of principal of or interest on any Loan (including, without limitation, any extension of the
Maturity Date) or any fees payable hereunder (including, without limitation, the waiver of any monetary Event of Default) or results in the expiration date of any Letter of Credit being after the Maturity Date; or 
 (iv) changes the amount of any Bank’s Commitment (other than pursuant to an assignment permitted under §20.1) or increases the
amount of the Total Commitment except as permitted hereunder; or 
 (v) modifies any provision herein or in any other Loan
Document which by the terms thereof expressly requires Unanimous Bank Approval; or 
 (vi) changes the definitions of Required
Banks or Unanimous Bank Approval. 
 No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent
thereon. No course of dealing or delay or omission on the part of the Agent or the Banks or any Bank in exercising any right shall operate as a waiver thereof or otherwise be prejudicial to such right or any other rights of the Agent or the Banks.
No notice to or demand upon the Borrower shall entitle the Borrower to other or further notice or demand in similar or other circumstances. 
 Notwithstanding the foregoing, no amendment or modification to §16 or to the fee payable to the Agent under this Agreement may be made without the prior written consent of the Agent, and the waiver of any fee payable to the Agent shall
require only the consent of the Agent. In addition, no amendment or modification to or waiver of the provisions of §2.8 may be made without the prior written consent of the Swingline Lender or of the provisions of §§3.1 through 3.6
may be made without the prior written consent of the Fronting Bank and, without limitation of the provisions requiring Unanimous Bank Approval or the consent of the Required Banks, no amendment or modification to or waiver of the provisions of
§2.9 may be made without the prior written consent of those Banks holding more than 50% of the outstanding Bid Rate Advances at the applicable time of reference.

 §29. SEVERABILITY. The provisions of this Agreement are severable, and if any one clause or
provision hereof shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner
affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction. 
 §30. INTEREST RATE LIMITATION. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Bank holding such Loan in accordance with
applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been
payable in respect of such Loan but were not payable as a result of the operation of this §30 shall be cumulated and the interest and Charges payable to such Bank in respect of other Loans or periods shall be increased (but not above the
Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Bank.

 §31. USA PATRIOT ACT, ETC. NOTICE. Each Bank that is subject to any of the Acts (as
hereinafter defined), the Arrangers and the Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001))
and other applicable federal or other laws with respect to the verification of customer identities (collectively, the “Acts”), it is required to obtain, verify and record information that identifies the Borrower, which information
includes the name and address of the Borrower and other information that will allow such Bank, the Arrangers or the Agent, as applicable, to identify the Borrower in accordance with the Acts.
